CTT Delivers Great Content to Chemists The 2011 Coatings Trends & Technologies (CTT) conference, a technical symposium organized by PCI Magazine and the Chicago Society for Coatings Technology, took place September 13-14 at the Doubletree Hotel in Oak Brook, IL. Attendees and exhibitors alike raved about the new, expanded venue for the event, which included two large ballrooms for the double-track sessions, as well as a 7500-squarefoot ballroom for the exhibitors to display their products. The conference had 248 registered attendees and 49 exhibitors, both up from last year. This year’s keynote address was by Dr. Richard Jenkins, Global Group President, Arkema Coating Resins. Jenkins’ presentation was titled Coating Resins and Additives – a New Global Perspective. He discussed how the coatings industry is growing globally, but not uniformly, and that growth drivers vary according to region. The environment and performance are driving the industry in mature markets, while population and construction growth are the driving forces in emerging countries. In addition, coating growth is greater than the GDP, and as economies emerge, the need for coatings and technology is going to increase. Jenkins stated that for suppliers, an effective response to market trends requires balancing global leverage with regional needs. Some issues are discreet by region, such as the substrate to be painted, weather conditions, latitude (UV intensity), market size and growth rates, economics and personal income, target aesthetics, and paint seasonality. Global, or multiregional, factors include technology platforms, paint manufacturers and commodity ingredients. The key, according to Jenkins, is to balance the global with the regional – to bring global technology and marketing leverage to all customers, but focused to their regional needs.

Jenkins also included a variety of interesting statistics about the global coatings market, including the preferred technology mix by region (solventborne, waterborne, powder and UV), the preferred paint sheen by region, as well as information on the volatile hydrocarbon feedstock costs and the resulting influence on resin selection. Over the course of the 1 1/2-day event, 31 technical presentations were delivered. Some of the topics included trend-setting pigment technologies, accelerated weathering, a new freeze/thaw highthroughput test method, silicon carbide “whiskers” for tough polymeric coatings, and nano-additives. Attendees that visited all 49 booths were entered into a raffle for three prizes: Michael Misiaszek, Lab Chemist at TPR2, won a $50 gift card; Keith Quisenberry, Senior Product Development Chemist at Franklin International, won a Wi-Fi Kindle; and Charles Billstrand, Senior R&D Chemist at GTI Chemical Solutions, won a 47” Vizio HDTV. It was great to meet with both coatings suppliers and manufacturers at this event, and to hear about some exciting new technology. Look for articles in upcoming issues based on presentations given at CTT. Mark your calendars now for September 11-12, 2012, at the same excellent venue, so that you can be sure to be a part of this growing annual conference!

Q

I am formulating waterborne alkyd coatings and need defoamer additives to improve my coating manufacturing, application and performance properties. What can you suggest?

Waterborne alkyd coatings are gaining popularity due to their enhanced properties, green chemistry and low VOCs. However, like most resins, waterborne alkyd coatings require specific defoamers to achieve optimal performance. Defoamers reduce or eliminate foam and help avoid production, application and applied coating problems. Our studies demonstrate that Surfy¯nol® DF-58 and DF-66 silicone defoamers (used at 0.05% to 0.5% of total formula) and Surfy¯nol DF-75 organic oil defoamer (used at 0.2% to 1%) provide excellent compatibility and defoaming. These additives enhance gloss of high-gloss coatings and provide excellent substrate coverage, appearance and protection. In wood coatings, such as clear varnishes and stains, they promote complete coverage, smooth finish, and excellent gloss, clarity and distinctness of image. In industrial coatings, such as metal primers, they eliminate defects such as pinholes, craters and other defects that can lead to corrosion, disbondment and other failures.

Updated Study of Pigments Market Now Available KONSTANZ, Germany – Ceresana Research has released a newly updated, in-depth study on the global pigments market, which states that pigment revenues will increase to more than $45 billion by 2018. In 2010, the Asia-Pacific region was responsible for 45 percent of the global demand for pigments. The second-largest market was North America, followed by Western Europe. Ceresana anticipates that the Asia-Pacific region will continue to significantly influence market dynamics in the future. The rapidly developing emerging markets have the greatest growth potential, above all China and India. Moreover, South America and the Middle East register above-average growth rates of 3.6 percent to 4.4 percent. Iron oxides and organic pigments record the highest growth rates in North America and Western Europe. In emerging markets, the demand for carbon black pigments is especially increasing. Ceresana expects that titanium dioxide will have a share of somewhat more than 60 percent of the global pigment market in 2018.

Researchers Unlock Mystery of “Coffee Ring Effect” ARLINGTON, VA – If you’ve ever spilled a drop of coffee on a surface, you might have noticed the curious way the color concentrates at the edges when the coffee dries. This is known as the “coffee ring effect”, and recently, researchers have determined that the shape of the particles in the liquid is an important factor in creating this pattern. The research results could eventually translate into new techniques or formulations for product coatings, or better inks and paints. This work, published in the August 18 issue of the journal Nature, was performed by Arjun Yodh and colleagues at the University of Pennsylvania. “We found that if you change the shape of the particles in the solution, the coffee ring effect goes away, and you end up with a uniform coating,” said Peter Yunker, a graduate student in Yodh’s lab.

Pigments have always been used primarily as colorants. However, secondary properties are gaining importance, for example protection from UV rays or corrosion prevention. Product innovations primarily aim at organic, effect and special pigments. The focus is on higher color intensity, color variety and additional properties, such as self-cleaning and antibacterial characteristics, insulating properties, or the reflection of infrared light. For additional information, visit www. ceresana.com/en/market-studies/additives/pigments-new/.

As the liquid in a droplet evaporates, the edges remain fixed, so as the volume decreases, fluid flows outward from the middle of the droplet to its edges. This flow carries particles to the edges, and round particles at the edge will pack closely. By the time all of the liquid in the droplet evaporates, most of the particles will be at the edge, producing the coffee ring effect. Both the shape that liquid droplets take and the way the shape changes as the droplets evaporate are greatly influenced by surface tension at the air-liquid interface. This tension is a property of the interface based on how the molecules in the liquid interact with one another versus the air. For example, liquids with a high surface tension, like water, may form a raised droplet, because the molecules are very attracted to one another and not so attracted to the air. In contrast, liquids with lower surface tension, like alcohols, are more likely to form flat spots instead of curved droplets.

I N DUSTRY NEWS The Yodh group found that elongated particles in a liquid behave differently than round ones because of the way they are affected by the surface tension of the air-liquid interface. “If you make the particles elongated or ellipsoidal, they deform the air-water interface, which causes the particles to strongly attract one another.” explained Yunker. This clumping changes the way the particles distribute themselves within the droplet. Even if the clumped ellipsoidal particles reach the edge of the droplet, they do not pack as closely as round particles. The loosely packed clumps eventually spread to cover the entire surface, filling it so an even coating of particles is deposited when evaporation is complete. “This work gives us a new idea about how to make a uniform coating, relatively simply. If you change the particle shape, you can change the way a particle is deposited. You can also make mixtures. In some cases, even just a small amount of ellipsoids can change the way the particles deposit when they dry,” said Yodh.

NDSU Bio-Research Promises Game-Changing Technology FARGO, ND – Several agricultural crops could play a significant role in bio-based resins and coatings recently developed by researchers at North Dakota State University (NDSU). Scientists at NDSU have developed bio-based resins that may prove to be a game changer in coatings and resin technology. The NDSU researchers have developed a family of resins from renewable raw materials, creating resins that eliminate hazardous components such as formaldehyde and bisphenol-A. The resins are based on sucrose and vegetable oils and can be varied to perform in many applications and industries, according to Dean Webster, Professor in the NDSU Department of Coatings and Polymeric Materials. The resins developed by the NDSU research group can be made from sugar beets, plus oils from soybeans, flax and sunflowers. When cured, the patent-pending resins show significantly

improved properties over current biobased materials and processes, mechanical properties comparable to petrochemical-based materials, and dramatically increased renewable material content. Webster’s research group found that the epoxidized sucrose ester resins they developed result in materials that are two to four times times as functional as vegetable-oil-based resins.

CSM and BASF Explore Bio-Based Succinic Acid JV DIEMEN, the Netherlands – BASF SE and Purac, a subsidiary of CSM nv, have begun negotiations to form a joint venture for the production of bio-based succinic acid. The companies have been conducting research under a joint development agreement on biobased succinic acid since 2009. The complementary strengths in fermentation and downstream processing led to the development of a sustainable and highly efficient manufacturing process based on a proprietary microorganism. The demand for succinic acid is anticipated to grow strongly in the coming years. The newly developed process combines high efficiency with the use of renewable substrates and the fixation of the greenhouse gas CO2 during production. This results in a positive eco-footprint and makes bio-based succinic acid an economically and ecologically

attractive alternative to petrochemical substitutes. The employed microorganism Basfia succiniciproducens is a natural producer of succinic acid and can process a wide variety of C3, C5 and C6 renewable feedstocks, including biomass sources.

IR-Reflecting

I

t is well known that modern IR-reflecting inorganic complex pigments not only impart super-durable colour shades to a surface, but enable coatings formulators to create products showing less interaction with solar radiation compared to using normal pigments, and therefore showing lower heat build-up. The most well-known application is found in the area of coil coatings for facades and roofs (key word: cool roofs). The aim is to lower heat transfer into buildings, and as a result reduce energy consumption of air conditioners to cool down the interiors. A positive side effect – an enhanced lifetime of the coating due to reduced thermomechanical impact – has been observed. There are several programs available that define criteria and approve products for cool roof applications. Of these, the Energy Star and Cool Roof Rating Council of the United States are the best-known programs. Further programs are Green Globes (Canada and United States), LEED (United States) and

one from the Singapore Environment Council. In Europe a similar program called Cool Roofs Europe has been started, and first products have been approved. While the application of IR-reflecting pigments in coil coatings is accepted and subject to constant improvement, further applications are under development. This article will describe recent findings in car refinish paints and plasters for architectural thermal insulation systems, and present a new dark IR-reflecting pigment combining jetness with high solar reflection.

Influence of Solar Radiation on Pigments Pigments interact with solar terrestrial radiation as described in Figure 1. Possible interactions are absorption (transmission), reflection and scattering. The interaction of colour pigments with the visible part of the electromagnetic spectrum (380 – 780 nm) is obvious in the form of our colour impression. Pigments can additionally interact with UV radiation (250 – 380 nm) and/or near-infrared (NIR 780 – 2500 nm) radiation. While the (detrimental) influence of UV radiation is well known (i.e., pigment fading), the interaction with the NIR radiation is its poor invisible cousin, although the integral energy of the NIR radiation accounts for approximately 50% of the total integral energy of solar radiation.

The amount of total energy absorbed and emitted by a topcoat determines the heat build-up of a coated surface and results in a final surface temperature after reaching an equilibrium state. Coating pigmentation has the main influence on heat build-up performance. To achieve cool surfaces, the pigments need to reflect as much energy as possible. This reflection ability can be expressed as the Total Solar Reflectance value (100% = total reflection; 0 % = total absorption). Therefore, pigments with high TSR values show a high reflection combined with low heat build-up, and vice versa. Pigments with the highest reflection ability are based on TiO2, while pigments with the lowest reflection are based on carbon black. If, from an aesthetic point of view, one prefers a dark colour instead of white, there is a choice of using dark inorganic complex pigments like P.Br. 29 (Chromium Iron Oxide) or P.Bk. 30 (Chrome Iron Nickel Black Spinel) as an IR-reflecting option. These pigments show higher TSR values compared to carbon black and are an excellent choice for grey colour shades; in mono-pigmented systems the TSR value is higher but the jetness is lower compared to carbon black. Figures 2 and 3 illustrate TSR values of different pigmented topcoats with the corresponding heat build-up measurements.

Although the use of black inorganic complex pigments with higher TSR values compared to carbon black is unlikely in full-shade car refinishes or OEM topcoats due to missing jetness, there is still some room for it in the total multi-layer set-up.

Heat Build-Up Effect in a Composite Thermal Insulation System Modern composite thermal insulation systems are used to keep the interior of buildings warm in winter and cold in summer to reduce energy consumption for heating and cooling. The insulation layer (commonly expanded polystyrene, EPS) largely reduces heat transport in any direction. The darkness of the applied plaster on the EPS is limited, as it may suffer from thermal/thermomechanical stress, especially at the interface between the plaster and EPS layer. Therefore, thermal insulation systems are only offered to a certain point of luminosity values, indicating the darkness of the plaster. Using IR-reflecting pigments, the heat build-up on the composite thermal insulation is reduced, with an expected positive impact on prevention of premature failure (Figure 7). As a consequence, using (dark) grey products with lower luminosity values is becoming a reality. In a lab experiment, grey plasters with a 1/3, 1/9 and 1/25 standard depth (STD) were formulated using different

Conventionally, pigmented topcoats (high-performance organic pigments) are transparent or at least partially transparent to NIR radiation. As a consequence, the NIR radiation passes through the topcoat, and the IR reflectance ability of this multi-layer system is then determined by the behaviour of the next layer, in this case the primer. Primers are available in different colours, including light grey and dark grey, to support the colour of the topcoat (in case of scratches). We modified a conventional white primer to a light grey and a dark grey primer, one modification with carbon black, the other with inorganic IR-reflecting black. Both modifications were tinted to the same colouristic values. Due to the better tinting strength of carbon black, a higher amount of inorganic black was necessary to achieve the similar colouristic result (Figure 4). The light grey and the dark grey non-NIR primers showed an approximate 8 °C higher end temperature compared to the white or the NIR primers. Especially remarkable is the very small difference between the white and the two NIR primers, which prove the efficiency of using IR-reflecting inorganic blacks (Figure 5). To check the influence of the primer pigmentation, we applied a blue and a red basecoat, including a clearcoat, onto the different primers to complete the full automotive refinish set-up (Figure 6). In practice, a red basecoat is more likely to be combined with a white or light grey primer, while a blue basecoat is more likely to be combined with a light or dark grey primer, but not a white one. The TSR values including the maximum temperatures of the heat build-up measurements of different multilayer combinations are listed in Table 1. In both cases (red and blue basecoat), the modification of the standard grey primers (containing carbon black) with inorganic IR-reflecting black pigments showed a significant effect for the multi-layer set-up in total performance.

brium temperature compared to the systems using P.Bk. 30 or P.Br. 29 (Figure 8). Following these lab findings, outdoor exposure tests were performed. During an extraordinarily warm summer day (38 °C maximum temperature), samples coloured with PBk30 and PBk7 at 1/3 STD and P.Br. 29 and PBk7 at 1/9 STD were placed in the sun in Langelsheim, Germany (51.9°N, 10.3°E) facing south. While the non-NIR reflecting samples reached surface temperatures of around 100 °C, the NIR-reflecting modified samples stayed approximately 10 °C cooler (see set-up of experiment in Figure 9 and summary of results in Table 2). Considering the thermal form stability of EPS (depending on compressive stress by load) to be 75-85 °C in longterm and 100 °C in short-term, many EPS manufacturers recommend keeping temperatures < 75 °C. The finding of temperatures up to 102 °C prompted the question: can a detrimental ageing effect be observed? This was tested in our lab with non-NIR-reflecting and NIR-reflecting modified samples (Figure 10).

Besides the well-known application of IR-reflecting pigments in coil coatings, possible benefits in two other areas have been found, and a new inorganic black pigment combining jetness and high TSR value was developed. In multilayer systems, it is possible to formulate brilliant surfaces combining the brilliance of an NIR transparent topcoat (organic pigments) with the NIR reflection ability of the below primer layer (NIR-reflecting pigments instead of carbon black) to reduce heat build-up of the whole system. Such multilayer systems can be found in automotive OEM or refinishes, as well as in other industrial coatings applications. Although in the automotive industry research is currently focused on optimizing the window glazing due to its higher influence on heat buildup in the car interior, it can be expected that attention will turn back to the coating once the research for glazing is finished and the contribution of the car body/reflective coating gets higher again in relation. Positive findings for lower heat build-up of thermal insulation systems using IR-reflecting black pigments instead of carbon black or black iron oxide have been reported for lab and outdoor tests. Detrimental effects on the dimensional integrity of the expanded polystyrene insulation layer can be seen under real outdoor conditions, which can be minimized using IR-reflecting pigments. All in all, one can expect lower energy consumption for cooling building interiors as well as an enhanced lifetime of the thermal insulation system, reducing thermomechanical stress at the EPS/plaster interface. A new inorganic black pigment has been developed combining jetness and a neutral colour shade in reductions with an extraordinary IR-reflecting ability bridging the gap between existing products.  Note: Cited TSR values have been determined in a 20% pigmentation in alkyd/ melamine. The powder pigments themselves show even higher TSR values.

ability, it seems to be common rule that pigments with higher jetness show lower TSR values. Therefore, the market demands products with higher jetness without reducing the TSR-value. Heubach GmbH has now added a new product to its product line of IR-reflecting pigments, combining higher jetness and a neutral colour shade in reductions with an extraordinary NIR reflecting ability. Figure 11 compares the reflectance spectra of different inorganic black options. The new product has an extraordinary high TSR value of approximately 17% (see integral spectrum from 250 nm – 2500 nm). The main difference compared to products that typically show such high TSR values can be seen in the visible part of the spectrum, especially between 650 nm – 800 nm (Figure 11). Here the reflection is lower, resulting in a more neutral colour shade (Figure 12) and a higher jetness. While in full shade, the new pigment is more neutral compared to P.Br. 29 (Figure 12). This behaviour can also be found in the 1:1 reduction (Figure 13). To achieve this colour shift to the more neutral side while staying with the higher TSR value, a lower tinting strength needs to be accepted.

New Developments in Pigment Dispersing Agents Improve Performance and Reduce Energy Consumption

T

o achieve the greatest cost-effective product performance in coatings and inks, it is essential to have maximum utilization of the pigments in the system. Typically, efficient and effective preparation and utilization of stable pigment dispersions leads to maximum color development from the dispersed pigment. More intense color development can result in the formulator requiring less pigment to reach the same color. Alternatively, it could reduce the energy needed during the pigment dispersion process due to the fact that less grind time is required to reach the level of color desired. This article presents three separate types of polymeric dispersants

that enable the formulator to create dispersions that utilize the properties of pigments to their upper limit.1

The Dispersion Process The dispersion process is generally considered to consist of three distinct stages that take place either sequentially or simultaneously. These stages are wetting, reduction of agglomerate size or separation, and stabilization. The dispersion system will lose some of its optimum properties should any of these factors be compromised. This decline in properties can manifest itself in such things as a loss of color development or dispersion stability.

Wetting The wetting stage can be described as the process of bringing particle agglomerates into intimate contact with the grinding medium. It involves preferential displacement of gases, liquids and other contaminants from the surface of the pigment with the grinding medium.2 The dispersing agent can assist greatly in this process by acting to form the direct grinding medium/pigment interface needed for creating a stable dispersion. In most cases, a substantial amount of the wetting process can occur without the use of mechanical energy, particularly when a proper, efficient dispersing agent is used.

Particle Size Reduction This stage is also referred to as “dispersion” or deflocculation. It generally includes mechanical action, which leads to agglomeration size reduction. The eventual target is a particle size distribution that exhibits the optimum set of properties for the pigment system.

Stabilization The stabilization process can also be known as controlled flocculation. There will be some minor flocculation in most dispersions as dispersant molecules are in motion. However, the best dispersants will keep the pigment particles separated to prevent interactions that would reverse

Dispersion Mechanisms The literature generally sites two types of stabilizing mechanisms: charge stabilization and steric or entropic stabilization.2 However, the polymeric dispersants introduced in this article also use what can be called “electrosteric” stabilization, a designed combination of the two well-known mechanisms. Charge, or electrostatic stabilization, is a result of preferential adsorption of the charged dispersant molecules onto the surface of the pigment particle and the thickening of the charge layer within the surrounding medium.3 The choice of dispersant can influence the magnitude of the repulsive energy, as can the ionic character of the medium. As a result, electrostatic stabilization is susceptible to and less stable in high electrolyte conditions. Steric, or entropic stabilization, is a result of dispersant structure in which one functional moiety or anchoring group has a strong affinity for the pigment surface, and extending into the medium are solvated polymeric stabilizing chains.4 The solvated chains lose their degree of freedom as particles approach each other, and this leads to repulsion to overcome the change in entropy. This method of stabilization is not affected by high electrolyte conditions. Electrosteric stabilization is the combination of the two traditional types. It could be referred to as the best of both types.

Program Objective The program objective was to evaluate three distinctly different types of polymeric dispersants to determine their performance in three separate case studies. In all three studies, these polymeric materials will be compared to competitive samples that are commercially used in the dispersion industry today.

anchoring group on one end and the branched stabilizing chain extending from it.

Type 2 The Type 2 polymeric dispersant evaluated is an ABA triblock copolymer. In the B chain it has multiple points of anchoring for excellent adsorption. The two stabilizing tails (A chains) extend into the medium for added density of the steric barrier. An example of the triblock material is shown in Figure 2.

the properties achieved by proper wetting and agglomeration size reduction. The polymeric dispersant molecule acts by adsorbing onto the pigment particle and providing a barrier against particle agglomeration. To make the dispersion complete, it is important for the wetting stage to continue as the optimum particle size distribution is reached. As the agglomerates continue to be broken, the new particle surface needs to be wetted to avoid the reformation of the agglomerate. A normal dispersion process will have some reversibility, and an amount of flocculation will occur.

Dispersant Candidate Types The candidates evaluated in this program can be divided into three types. They are as follows.

Type 1 Type 1 of the polymeric dispersants tested can be described as a non-emulsifying dispersant in that it does not have the typical hydrophobe/hydrophile structure of a surfactant. These materials are specifically designed as dispersants. They have an anchoring group that has a strong, specific interaction with the pigment surface, and a polymeric stabilizing group that is compatible with the medium and extends out, providing steric stabilization.

A comb graft polymeric dispersant is the best description of the Type 3 structure. The steric stabilization is provided by the comb “arms” extending from the backbone into the medium, while electrostatic stabilization is established by the acidic functionality of the backbone itself. An

example of the comb graft structure is shown in Figure 3.

nonaqueous binder with three different types of organic pigments. Three separate paints were made with the nonaqueous binder and the pigments. All of the paints used a competitive dispersant that had been causing issues with dispersing the pigments. This study used a Type 1 anionic polymeric dispersant, with the nonaqueous binder and the three pigments; it compared paints with the competitive dispersant to paints with the Type 1 anionic polymeric dispersant.

Yellow Pigment Dispersed in Nonaqueous Binder The first part of the study presents the data on a yellow organic pigment dispersed in a nonaqueous binder. The dispersant was added to the sample and the yellow pigment added at a 17% by weight loading level, indicating a low solids-type paint. The sample was then dispersated at 5000 rpm for 5 min. Figure 4 shows the difference between the viscosities of the two paints based on the pigment dispersant used. Temperature point 1 was the viscosity taken at 20 ºC, whereas Temperature point 2 was the viscosity after the samples were exposed for 67 h at 50 ºC, and then allowed to cool down. While the competitive dispersant showed reduced viscosity after exposure to 50 ºC for 67 h, the sample also had a large amount of agglomeration on the sides and bottom of the container. The Type 1 anionic polymeric dispersant showed lower viscosity in both tests, and did not have agglomeration in the container after testing at both 20 ºC and 50 ºC. The yellow paint samples presented in Figure 5 show the difference in the capabilities of the two different pigment dispersants when used in this nonaqueous binder after exposure to 50 ºC for 67 h.

petitive dispersant, whereas the sample labeled JEH-1-38B (right) is the paint with the yellow pigment dispersed by the Type 1 anionic polymeric dispersant.

Orange Pigment 1 Dispersed in Nonaqueous Binder The second part of the study involved dispersating an organic orange pigment (hereafter referred to as orange pigment 1) in the same nonaqueous binder. The dispersant was added to the sample, and the orange pigment 1 was added at a 14% weight loading level. After the additions, the paint was dispersated at 5000 rpm for 5 min. Figure 6 shows the results of the viscosity testing on the paints made with the orange pigment 1 in the nonaqueous binder. Temperature point 1 shows the viscosity results taken at 20 ºC before exposure to higher temperatures. Temperature point 2 shows the viscosity results taken after the samples were exposed for 50 h at 50 ºC. While both samples showed increased viscosity after exposure to 50 ºC for 50 h, the competitive dispersant showed outgassing often associated with a reaction occurring between the binder and pigment, whereas the Type 1 anionic polymeric dispersant remained fluid, with no signs of reactivity between the pigment and binder. Orange Pigment 2 Dispersed in Nonaqueous Binder The third part of the study involved dispersing another

organic orange pigment (hereafter referred to as orange pigment 2) in the same nonaqueous binder as the previous pigments. The dispersant was added to the sample, and the orange pigment added at a 14% weight loading level. After the additions were made, the paint samples were dispersed at 5000 rpm for 5 min.

A study was done that examined the performance of two different pigment dispersants in an inorganic pigmented aqueous binder that had a pigment loading of greater than 70% by weight. The current dispersant, competitive dispersant 2, was unable to disperse the pigment fully, resulting in hard agglomerations on the bottom of the containers; or separation of the pigment from the binder. A Type 1 polymeric dispersant was used to overcome these issues in high pigment loading aqueous systems. While the pigment was added in at 70+% by weight loading level, each dispersant was used at 2% by weight on pigment. After the addition of the pigment, the paint was dispersed at a range between 1500 and 4000 rpm depending on the difficulty of dispersing the pigment. All samples were dispersed for 5 min. The results shown in Table 1 indicate that the colorant that used the competitive dispersant 2 was unable to fully disperse the inorganic red iron oxide pigment when used at that high loading level. The sample showed hard packing and displacement of the pigment from the binder. Type 1 polymeric dispersant was able to disperse the red iron oxide pigment in the aqueous binder and keep it dispersed with no displacement from the binder. Figure 9 shows the viscosity measurements taken at different temperature points on the two colorants. Temperature point 1 was the initial viscosity taken after each sample was dispersed and cooled down. Temperature point 2 was viscosity measurements taken after exposure for 5 days at 70 ºC, then cooled down. Temperature point 3 was after 5 days at room temperature (20 ºC). The competitive dispersant 2 samples had a greater viscosity at the start of testing and continued upwards, increasing in viscosity the longer the sample remained. The Type 1 dispersed samples showed decreased viscosity of the colorant over time, without increasing agglomerations or precipitating out the pigment from the binder. The photo presented in Figure 10 shows the separation that occurred in the competitive dispersant 2 colorant after exposure at 70 ºC for 5 days. Figure 11 shows that after 5 days of constant exposure to 70 ºC, no separation occurred between the pigment and the binder.

Study 3. Color Development and Viscosity Studies Viscosity and color development studies were completed in the laboratory using 4-ounce paint cans. The cans were filled with the grinding medium and the appropriate type of polymeric dispersant. The pigment or metal oxide was slowly added while mixing to assure all the solids were wetted out. At this time, ceramic beads were added for grinding. The mixtures were then put on a Red Devil paint shaker for 1 h with samples being removed every 15 min. Viscosity tests were performed only on the 1 h samples, while color development evaluation was done on the samples that were removed every 15 min. The results of the viscosity studies completed showed significant advantage in using one of the polymeric dispersants. In Figure 12, the viscosity advantage using a Type 1 polymeric dispersant is readily evident. The formulator would therefore be able to significantly increase the solids loading and still have a usable final viscosity.

Color Development The samples taken every 15 min were mixed into either a clear base (masstone) or a typical trade sale white tint base. In all cases in this study the focus was water-based systems. As can be seen from Figures 13 and 14, the Type 3 polymeric dispersants have a significant advantage over the commercial competitive material in development of color.

FIGURE 14 | Color development comparison using blue 15:4 in white tint base. Color Strength (%)

In both Figures 13 and 14, the 100% color development value was set by the 60 min grind for the control or competitive sample. In both cases, color development of greater than 100% was reached very quickly using the Type 3 polymeric dispersants. It is therefore readily apparent that, in addition to higher color development capability, the Type 3 polymeric dispersants in these evaluations offer the cost savings potential of grinding for less time to reach equal or greater color development. Thus, the producer will have two potential routes to cost savings.

Conclusion Three types of polymeric dispersants have been evaluated in the study presented. Each of the types has shown utility in application testing. It has been illustrated that these materials provide improved wetting and dispersion that results in efficient milling that can provide greater color development or higher productivity and energy savings. Lower viscosity after grinding is also a feature of these polymeric materials. This viscosity advantage results in the ability to have higher solids loadings, resulting in higher productivity and lower inventory requirements. Additionally, improved stability of the dispersions produced with the polymeric materials provides longer shelf life and therefore lower storage loss.

of Partially Melted Powder Resulting from

T

he grinding of solid materials to produce powders is a common manufacturing step found in many industries. In the coatings industry, grinding may be used in the preparation of pigments and of powder coatings. Of particular focus in this article is an application solution successfully deployed in the production of powder coatings. In the powder coating industry, several different types of polymeric matrices are dealt with. These include epoxies, epoxy polyesters, polyesters, acrylics and polyurethanes. Each material has its own mechanical and physical properties, but, when converting any of them from feedstock chips to ground powder, the friction of the grinding process itself generates a sufficient amount of heat to cause a quality problem resulting from the agglomeration (“clumping”) of partially melted powder particles or heat-induced changes in ground material properties. This problem is worse when the ambient temperature is high. The quality burden on the manufacturer is two-fold: • First, it becomes necessary to inspect all batches proactively, immediately after processing and again after a short storage period; • Second, any failed material requires re-processing – followed by a second round of inspection (possibly leading to additional re-processing and re-inspection). The economic and productivity benefits of minimizing – or totally eliminating – the problem are intuitively obvious.

Characterizing the Problem At Spraylat, high-throughput grinders are used in combination with sifters to grind the feedstock chips and collect properly sized powder – the target particle size range is 35

to 65 microns, depending on the product. The grinding and sifting equipment itself is not unusual. Processed material is collected into cardboard boxes, fiber drums and large gaylords, each lined with a plastic bag, with a capacity ranging from 50 lb per box up to 1500 lb per gaylord. Ambient temperature in the processing area is normally in the range of 75 °F – 77 °F, but can climb to levels as high as 85 °F in the summertime. The temperature of the powder in an in-process container (i.e., during fill) can reach 100 °F. At first, it was noted (entirely empirically) that agglomeration was problematic when packing into large gaylords on hot days The mass of the material insulates the core of the container, causing heat dissipation to be slow. As a result of exposure to the high temperatures – for prolonged periods – material at the core of the container fuses, creating clumps of “out of specification” material. Higher ambient temperature outside of the container aggravates the problem of heat dissipation. When processed powder fails to meet quality specifications, it must be reprocessed. The reprocessing has an obvious impact on lead times, production throughput and production costs.

Initial Outcomes Based on the information in hand, attempts were first made to lower the ambient temperature in the processing area. It simply was not practical to enclose the area effectively; and ambient air cooling, while partially effective, proved insufficient. Experiments were also conducted combining the use of ambient temperature cooling with “pre-chilled” material. While some improvements were noted, these improvements were still not sufficient to eliminate the need for ongoing batch inspections or for frequent batch reprocessing. Spraylat also manipulated the process of the material itself. After extrusion, Spraylat altered various controls to allow better pre-cooling of the material, before the material went to the grinding stage. Again, this showed improvement, but was not good enough. The end result of these initial investigations was not a solution at all, but what can best be characterized as a “pragmatic work-around.” The processing procedure was revised to require continuous monitoring of the temperature at the core of the collection container. If the temperature exceeded 82 °F (well below the temperature at which problems were observed) at any time during processing, the container was tagged for repro-

the Grinding Process cessing. There was no option for additional testing; the only option was to reprocess. The pragmatic work-around was a quality success – quality standards were met consistently. However, it did nothing to address the problems of lead time, throughput or production costs. It was determined that the temperatures of the cooler material and the temperatures of the environment would not defeat the heat developed in the process and that the pragmatic work-around would not serve as anything other than a temporary solution. Therefore, Spraylat considered the need for an alternative solution that would eliminate reprocessing in a way that was both cost effective and non-disruptive to the flow of work.

Consider Cryogens From past experience, Spraylat engineers knew that cryogenic liquids (such as nitrogen and carbon dioxide) could be used in grinding applications to lower the temperature of the ground material. Initial efforts were focused on justifying the benefits of using cryogens versus the disadvantages of adding another consumable and a variable to an already technologically complex process: 1. The capital expense of the required cryogen storage and handling equipment; 2. The ongoing expense of consumable cryogen; and 3. The costs of additional complexity (training, operation, maintenance, safety). Spraylat needed a supplier/partner that would help determine which cryogen was the best for the job, demonstrate that the cryogen cooling approach works, and ultimately, engineer a solution that would seamlessly integrate with Spraylat’s powder production process. MATHESON was a willing partner to assist Spraylat in reaching its objectives, minimizing the cost of trials and demonstration, and finalizing the commercial equipment design and installation, while also looking for ways to minimize ongoing consumption costs. MATHESON was also a willing partner to assist with training, maintenance, safety and other concerns.

2. As a GHG, carbon dioxide would be neither a popular choice nor one that was compatible with Spraylat’s policies on environmental sustainability; 3. Carbon dioxide might also pose a worker safety risk, because it is heavier than nitrogen and is more difficult to exhaust; 4. The supply of carbon dioxide is subject to seasonal allocations, and its pricing is impacted by supply chain disruptions and surcharges; and 5. Carbon dioxide is faintly acidic, which may react with the powder material or affect powder quality. Nitrogen had none of the disadvantages of carbon dioxide, and was identified as the cryogen of choice because of its efficacy as a cooling gas, availability, stable supply chain and zero environmental impact. Nitrogen composes approximately 79% of atmospheric air, and liquefied nitrogen is widely available, so supply is not a concern. Like carbon dioxide, nitrogen is a simple asphyxiant (does not support life), but is a much lighter gas, and is more easily vented. As a final advantage, liquefied nitrogen is widely used in a number of applications for chilling and freezing. It is easily stored, and equipment for handling liquid nitrogen is readily available and inexpensive. The obvious advantages of nitrogen over carbon dioxide made nitrogen a clear winner as the cryogen of choice for Spraylat’s application. Just as carefully, MATHESON considered the requirements of exhausting the spent cryogen vapor and recommended that oxygen deficiency monitors (with alarms) would need to be installed in poorly ventilated work spaces. As a first step, Matheson supplied a demonstration system, liquid nitrogen product, and the equipment necessary to connect the nitrogen supply to the demonstration system as well as for connecting MATHESON’s system to Spraylat’s equipment. The results of the trial exceeded Spraylat’s expectations (Figures 1 and 2). The MATHESON system performed well with several different types of

FIGURE 2 | Sifter and powder temperature profile with cooling.

There are several cryogens available, among which carbon dioxide and liquid nitrogen are the most popular. Carbon dioxide (CO2) is an effective cooling gas, but suffers some inherent disadvantages. 1. As a greenhouse gas (GHG), Spraylat would be required to monitor and report carbon dioxide consumption and release;

sifters, maintaining powder temperature to within +/-0.2 °F from a desired temperature set point. The results of the trial, combined with MATHESON’s track record of quickly developing a well-engineered solution within the required time frame and at a cost that provided Spraylat with the necessary economic justification, gave Spraylat confidence in the outcome.

System Design Considerations Liquid nitrogen is injected into the process from within the feed throat of the sifter (Figure 3). The exact location of the injection nozzle and the specific flow rate of nitrogen are subject to the configuration of the sifter and variables of the process itself. Detailed calculations fall outside the scope of this article, but general considerations are described below. The nitrogen injection system is activated when the grinding process starts to pre-cool the sifter interior before receiving any ground powder. The rate of liquid nitrogen injection is based on the temperature of the processed powder at the sifter discharge. The powder temperature is monitored by means of a thermocouple. An active proportional controller is employed to modulate the dosing of nitrogen. This prevents over-cooling and minimizes wasted gas. A separate thermocouple and temperature controller are used to monitor sifter temperature to ensure no over-freezing. In order to obtain effective cooling, the liquid nitrogen injector is located directly in the center of the powder feed duct and is pointed in the direction of the powder travel. This allows for sufficient contact time between the powder and the cold nitrogen fluid, which is necessary for the heat transfer to occur between the two. Liquid nitrogen changes from liquid phase to gas phase at -320.4 °F at atmospheric pressure. When injected into the powder feed upstream of the sifter, the nitrogen rapidly goes to gas phase. The brief contact between the comingled powder and cold, liquid-phase nitrogen is sufficient to cool the powder. Further cooling is achieved from the cold nitrogen vapor, which serves to “refrigerate” the immediate atmosphere in the sifter and the powder output chute. Generally, in order to lower the powder temperature by 10 °F, the nitrogen consumption rate is approximately 0.1 lb of liquid nitrogen per 1 lb of powder.

Eliminating Agglomeration of Partially Melted Powder Resulting from the Grinding Process

Importantly, the impact of nitrogen flow on final temperature is not linear, and is subject to many variables (such as grinding throughput, particle size and so on). The rate at which the cryogenic fluid is delivered into the powder stream, the powder feed rate and material properties will determine Liquid nitrogen control system. the amount of cooling that is available and the final temperature of the powder. The target powder temperature at the discharge of the sifter is 75 °F. Higher initial powder temperature or higher grinder throughput will require higher liquid nitrogen injection rates. If the initial temperature of the powder is lower, or if the grinder feed rate is lower, then less nitrogen will be required to cool the powder. In addition to process-specific and safety considerations, ease of use, cleaning and maintenance are just as important and were built into the system design.

Results Prior to using liquid nitrogen cooling, reprocessing had a detrimental effect on production schedule and cost. With multiple processing lines producing between 500 and 2000 lb of powder per

Due to production demands, there were scheduling conflicts and scarce time left available for maintenance, cleaning or product changes. The investment in a liquid nitrogen cooling system proved to be a very cost-effective solution to the powder agglomeration problem. With the liquid nitrogen system in place, quality failures due to particle agglomeration are zero. Production line scheduling is easier and more reliable. Lead times are shorter and more predictable. Due to optimized liquid nitrogen usage, the ongoing operating costs are low. After accounting for the capital costs of system installation, payback on the systems was estimated to be less than two years; after which time the continued use of the liquid nitrogen system would net an ongoing savings in operational cost.

RED COATINGS ENERGIZED BY Bayferrox® pigments are used for various applications to boost creativity and product performance. At shorelines around the world, they are indispensable in protective coatings – impressing with their excellent hiding power as well as with their easy and environmentally friendly use. A success story that is closely linked with the name of our chemist Julius Laux. In 1926, premium iron oxide pigments from nitrobenzene and scrap iron were produced on an industrial scale for the ȝrst time. The “Laux process” was born. This year, the “Laux process” turns 85 – and still represents the state of the art. As one of the world’s leading manufacturers of synthetic iron oxide pigments, we are proud to support you with this outstanding experience. www.bayferrox.us

Novel Application of Fluorosurfactants in

C

oatings on wood surfaces are mainly for protective and decorative purposes. In recent years, manufacturers of wood coatings have devoted their research and development resources to improving waterborne coatings due to their huge environmental advantage.1 Waterborne coatings offer finishers outstanding environmental benefits such as VOC compliance, lower odor and fewer harmful organic vapors, lower flammability, a safer and healthier workplace with fewer allergies and less skin irritation, and reduced fire hazards. Along with these come economic advantages such as lower insurance and storage costs, and lower hazardous waste disposal costs. They also allow for application advantages such as the ability to use existing application equipment to apply at varying thicknesses and reduced labor for clean up. However, the change from solventborne to waterborne coatings led to the development of more complex coating systems, containing more components. The surface tension of water (72 dyne/cm) is much higher than solvents. Simple VOC reduction without a proper surfactant package will cause many surface defects such as craters and orange peel, so wetting, leveling, foam control and surface repellency of waterborne wood coating are becoming ever challenging tasks for formulators. One effective solution is to add suitable additives to improve the performance. Surfactants in wood coatings provide two major functions; they ensure smooth application of the wet film and improve film substrate adhesion; and provide surface energy modification to improve the film’s repellency and chemical resistance. In a previous study, we demonstrated that fluorosurfactants can be used in low-VOC latex architectural paints

as multi-functional additives to provide wetting, leveling, anti-blocking, oil repellency and dirt pick up resistance properties.2 In this article, we discuss the role of fluorosurfactants in waterborne wood coatings and how they can be used as cost-effective additives to help improve surface tension reduction, wetting, leveling, oil repellency and chemical resistance in thin film applications. Almost all types of resins are now available to meet the specific needs in waterborne formulations like acrylics, epoxies, alkyds and urethanes.3 For waterborne wood coatings, the main coating systems include one-pack acrylic latex or dispersion, one-pack polyurethane dispersion (PUD) or PUD acrylic hybrid, one-pack alkyd, and two-pack waterborne polyurethane (polyol and isocyanate). The acrylic binders are generally produced by emulsion co-polymerization of various monomers to form colloidal stabilized solid particles in water (latex). Film formation of acrylic dispersions consists of water evaporation, followed by coalescence and finally by inter-diffusion of the polymer particles to form a film.4 Water-reducible polyurethane dispersions (PUDs) and polyurethaneacrylic hybrids offer near-urethane performance with the application ease of a one-component coating. In this chemistry, modified isocyanate molecules are stabilized in water and reacted with polyols before they reach the end user to form a waterborne polyurethane dispersion.3 This study used a waterborne self-crosslinking acrylic dispersion as the binder because waterborne, acrylic dispersion, air-dry coatings are widely used in wood finishing where a fast, low-temperature cure is needed. The films are hard and very fast drying.5 It is important that the use of fluorosurfactants will not cause recoatability issues in wood coatings, and our data confirms this.

For our experiment, the binder used was a medium-hard, self-crosslinking acrylic dispersion with MFFT of 113 ˚F. Five formulations were studied (formulations A, B, C, D and E) to evaluate the performance of various surfactants. Table 1 provides a generic summary of the composition of these five formulations. The formulation weight solids was 33-34% and the viscosity 8000-8500 cps. The paint (with 5% water reduction) was applied in three layers by conventional air atomizing spraying on an oak substrate; air pressure was 40-50 psi, with a time interval of 45 min. Dry film thickness of each layer was 55-60 microns.

Surface Tension Surface tension was measured with a KRUSS tensiometer

using the plate method. A thin plate was lowered to the surface of the liquid, and the downward force to the plate was measured to calculate surface tension.

TABLE 2 | Surfactant surface tension in DI water and binders. Dosage (%)

Fluorosurfactant

Oil Repellency The water and oil contact angles on coated wood substrates were measured using a Goniometer with a high-speed CCD camera for image capturing. Water or hexadecane was dropped onto the surface by a syringe. The computer-aided Goniometer measures a droplet’s contact angle by assuming the droplet fits the geometry of a sphere when the drop is stable after 1 min. A high oil contact angle value indicates a good oleophobic nature of the coating, while a low value indicates that the oil wets the surface.

Recoatability of the three layers was evaluated by an adhesion test (ASTM D 3359 crosshatch tape testing). Before the test, the paint films were air dried for 7 days.

Results and Discussion Foaming The surfactants were diluted with water to the same dosage in the paint formulations, and foam was generated by hand shaking. The volume of foam is shown in Figure 1, which was taken 15 sec after shaking. The figure shows that the four fluorosurfactants all generated less foam than the silicone surfactant. Zonyl® FS-610, Capstone ® FS-61 and Capstone ® FS-63 fluorosurfactants are especially low-foaming products, as there is almost no foam after shaking.

Novel Application of Fluorosurfactants in Waterborne Wood Coatings

Surface Tension Reduction

Wetting and Leveling

Surface tension of fluorosurfactants in deionized water and commercial wood coating binders is shown in Table 2. Water-reducible polyurethane dispersion (PUD) is also widely used in one-component wood coating systems due to its near-urethane performance. The reduction of surface tension was listed to compare with the studied acrylic resin. Compared to silicone surfactants, fluorosurfactants have the most power to reduce surface tension in water and water-based binders, especially in PUD resin. In four fluorosurfactants, the new-generation Capstone® surfactants showed better surface reduction abilities than Zonyl® products.

Coatings were sprayed on oak planks; the surface appearances of different formulations are shown in Figure 2. Optical microscopy photos (8x magnification) of the formulation using fluorosurfactant and silicone surfactant are shown in Figure 3. The formulations using Capstone® FS-61 and Capstone® FS-63 achieved good wetting and leveling performance in a low dosage of defoamer. The formulation using Zonyl® FSP had air foam in the surface, and serious surface defects such as cratering and orange peel were observed in the formulation using silicone surfactant. It is demonstrated that Zonyl® FS-610, Capstone® FS-61 and Capstone® FS-63 fluorosurfactants are helpful in improving wetting and leveling in waterborne wood coatings. Wetting is the action of the liquid coating as it spreads across a surface, and is essential for successful coating application. Wetting performance can be improved by two methods: 1) raising the surface energy of the substrate by cleaning, removal of contamination and pretreatment of substrate; 2) lowering the surface tension of the coating by the use of surfactants. If there is no change to the substrate, then it is crucial to lower the surface tension of the coating to achieve good wetting. Compared with silicon surfactants, fluorosurfactants are more effective in lowering the surface tension, which leads to better wetting performance. Leveling is the ability to achieve a smooth and uniform surface. It is a highly demanded attribute in high-gloss wood coatings and finishes. During film formation, numerous problems can occur, such as inadequate wetting of the substrate, poor flow, crater formation and pigment floating. These problems all influence the leveling performance. In general, leveling performance of coatings can be controlled by surface tension, rheology, film thickness, the evaporation rate of solvent and pigment dispersion. In our testing, factors such as thickener, dry film thickness and co-solvent are the same, and the difference is the surface tension of the paint. So it is reasonable to consider that better surface tension reduction of fluorosurfactants leads to better leveling performance compared to silicon surfactants. Fluorosurfactants promote substrate wetting to prevent craters, fisheyes and crawling, and the elimination of these surface defects is very helpful to achieve good leveling. Fluorosurfactants also can establish a uniform surface tension over the entire surface area due to their fast migration and good compatibility, which also are positive to leveling. Overall, the use of fluorosurfactants in waterborne wood coatings can help retain good gloss and even reflection, and smooth formation of the film.

The water and oil contact angles of different paint films are listed in Table 3, and Figures 4 and 5 show water and oil contact angles of different formulations. The water contact angle of the formulation using silicone surfactant is slightly higher than the formulations using fluorosurfactants. However, the oil contact angle of the silicone surfactant formulation is very small (near zero), meaning the oil stain or oil chemical can almost spread completely on the film surface. The oil contact angles of

fluorosurfactant formulations are much higher than silicone surfactant formulations, and oil beads up on the surface. This indicates the addition of fluorosurfactant can offer excellent oil repellency to paint film.

The adhesion of the formulations with fluorosurfactant was 5B, and the formulation with silicone surfactant was only 3B. This indicates that there is no negative effect of fluorosurfactant on recoat adhesion.

Novel Application of Fluorosurfactants in Waterborne Wood Coatings

Conclusion It has long been known that the surface tension of a liquid is the most important factor influencing wetting performance. In general, the lower the surface tension, the better the wetting. This becomes particularly important with the introduction of waterbased coatings. In water-based systems, due to the high surface tension of water, it is usually necessary to incorporate suitable additives to lower the surface tension, ensuring good wetting of the substrate. Wetting is especially difficult on substrates with low surface energy, such as plastics or on substrates contaminated by grease or dirt. Fluorosurfactants are the most efficient in lowering the surface tension to improve wetting and prevent surface defects. The elimination of these surface defects is also positive for flow and the improvement of leveling performance. One of the features of fluorosurfactants is that they are oleophobic or oil repellent. The use of fluorosurfactants can dramatically reduce film tackiness and enhance oil repellency, and improve chemical resistance. This multi-functional property is directly related to the improvement of dirt pick up resistance of exterior wood coatings. With respect to concerns about recoating, our study showed that there is no recoating issue when using fluorosurfactants in waterborne wood coatings. Compared to other classes of additives, fluorosurfactants have many advantages in waterborne wood coatings. Fluorosurfactants can:

• Most effectively reduce liquid coating’s surface tension; • Offer excellent wetting and leveling to the paint film; • Help the formulator simplify the formulation by reducing the need of defoamer and improve overall film quality; • Reduce film tackiness and enhance oil repellency, and improve the chemical resistance.

Rheology Additives in Waterborne Basecoats

olatile organic compound (VOC) regulations are driving changes in coating formulations to waterborne technology or to higher solids in solventborne systems. The first commercial-scale application of the waterborne basecoat in the automotive industry started in the mid-1980s. Since then, the performance and ease of application of waterborne basecoats have improved rapidly; along with the push from regulations, waterborne basecoats now take up more than 80% of the total basecoat market in Western Europe. In North America, roughly 55% of OEM basecoats and 20% of refinish basecoats are waterborne. Although waterborne coatings possess some intriguing advantages, there are difficulties that have to be overcome before successful application can be made. One of the most important problems is the control of the rheology, which determines the quality and appeal of the final film. A typi-

cal waterborne basecoat shear-thinning profile, and the ranges of shear rate that a basecoat would receive at each coating process are shown in Figure 1.

Challenges of Formulating Waterborne Basecoats Basecoat rheology should be carefully designed for a particular application such that the performance of the paint is superior during the entire handling cycle, from storage to spray application and drying. The required rheology should enable the basecoat to have a high viscosity during storage, which leads to minimal settling. Under moderate agitation and during circulation, the viscosity should be low to allow the basecoat to be easily pumped. At the spraying gun or bell, the viscosity should be very low so that the paint can be properly atomized. As soon as the paint is sprayed on to the target, the viscosity should build quickly to prevent paint from running or sagging. However, the viscosity should still be low enough to enable the paint to level off, providing a smooth film. Another important role for rheology additives in a basecoat is to help achieve desired colors that give the sharpest aesthetics. A properly designed rheology package should prevent floating/flooding and mottling. In a basecoat containing a specialty pigment such as aluminum flakes or pearlescent pigment, along with binder system, rheology additives are the key tools to help control flake alignment during flash-off and drying periods. Properly oriented pigment flakes not only increase hiding and durability of the coating film, they also bring out the maximum beauty of these expensive pigments: sparkling effect, maximum face brightness and high flop.

ity. As molecular weight of the polymer increases, high-shear rate viscosity of the system increases. Emulsion-type binders often show more thixotropic behavior as compared to polymer solutions. Their shear rate versus viscosity relations are impacted more by particle size and solids of emulsion solutions rather than molecular weight of the polymer itself. Heavy inorganic pigments tend to raise highshear rate viscosity; high pigment loading of organic pigments and carbon blacks tends to raise low-shear rate viscosity. In solventborne basecoats, microgels, waxes, bentonite and cellulose acetate butyrates (CABs) are commonly used as rheology modifiers. One of the advantages of using microgels is the low viscosity at higher levels of non-volatile content in a coatings formulation. Since microgels are prepared as non-aqueous dispersions (NADs), this is a category not available to waterborne formulations. Different from other rheology modifiers, a CAB solution in a common solvent exhibits near-Newtonian flow behavior. At the moment a basecoat is spray-applied to an object, the Newtonian characteristic of CABs help flow and leveling. Due to a rigid cellulosic backbone, CABs possess extremely high glass transition temperatures (Tg) as compared to other polymers used in coatings. High Tg of CABs results in a rapid viscosity buildup within a short period after a basecoat is applied, leaving no time for coated film to sag, as well as no room for pigment to swim. The combination of these unique properties provides a basecoat formulation with excellent flake orientation and color uniformity, which leads to quick dry-to-touch time and improved strike-in resistance in a wet-on-wet application. This will enable the basecoat to have superior flow and leveling without compromising sag resistance. For waterborne basecoats, instead of microgel, there are a variety of alkaliswellable emulsion-type rheology modi-

Alkali-Swellable Emulsions – Commonly used are hydrophobically modified alkali-swellable acrylic emulsions (HASE) and hydrophobically modified ethoxylate urethanes (HEUR). Viscalex™ HV30 is a very efficient thickener in this category available from BASF. Another type in this category are rheology-modified acrylic core/shell dispersions such as Setalux™ 6803 AQ-24 available from Nuplex. The dispersed particles consist of a hydrophobic core and an acid functional alkaliswellable shell. Upon neutralization with amines, the resin develops its unique, strong pseudo-plastic or thixotropic character essential in a waterborne basecoat. Wax Dispersions – There are polyamide-based aqueous dispersions such as Disparlon™, available from King Industries; and modified polyethylene dispersions such as Aquatix™ 8421, available from BYK. In general, wax dispersions are not as effective as alkali-swellable types, and they often increase high shear viscosity, which is undesirable. Bentonite – Bentonite refers to a family of layered silicate clays. Silicate clay is insoluble in water but hydrates and swells to give clear and colorless colloidal dispersion. At very low concentration in water, highly thixotropic gels can be produced. A well-known product in this category is Laponite™ RD, available from Rockwood Additives. Waterborne Cellulose Ester – Eastman Chemical has recently commercialized a waterborne cellulose ester, Solus™ 3050 performance additive, in an effort to pursue the benefits of CABs in solventborne formulations from waterborne chemistry. Performance benefits of Solus™ 3050 include superior flow and leveling, optimal metallic flake control and better redissolve/strike-in resistance.

Summary The protective coating industry is in a transition phase geared towards waterborne and high solids formulations. Selecting the right rheology package is the key to formulating optimized waterborne basecoats that possess desirable application fitness and best finishing appearance.

INSIDER INTERVIEW

A Closer Look at Ashland’s Acquisition of ISP PCI:

On May 31, Ashland Inc. announced its intention to purchase International Specialty Products Inc. (ISP) for $3.2 billion. The deal closed on Aug. 23, and brought two players in the coatings industry together. When you look at the acquisition, it reflects a combination of different functional platforms for the industry. As Ashland brought the newly acquired company into its portfolio, it renamed the combined businesses Ashland Specialty Ingredients. Over the next few months Ashland will continue integrating the former ISP with its former Ashland Aqualon Functional Ingredients commercial unit. John Panichella is president of the new Ashland Specialty Ingredients. PCI took the opportunity to ask Mr. Panichella a few questions about the acquisition and what the implications are for the coatings industry.

Panichella: Of course we are optimistic that the combined expertise of both companies will yield new technology and ultimately new products for our customers. We expect to be looking closely at the technologies we each have and how best to bring those together to identify potential technology synergies. As such, we are looking forward to bringing the scientific expertise of both organizations together. In addition, one of the attractive aspects of ISP was the robust nature of their new product pipeline. Look for coming announcements.

PCI:

Panichella:

How does the acquisition of ISP change or enhance Ashland’s focus on the coatings industry?

Panichella: There are a number of ways that Ashland’s acquisition of ISP enhances our customer offering to the coatings industry. First, consider our portfolio of additives prior to the acquisition, which was centered on our flagship product lines, Natrosol™ hydroxyethylcellulose and Aquaflow™ nonionic synthetic associative thickeners. These rheology modifier technologies, along with our foam-control additives (Drewplus™) and specialty surfactants (Dextrol™ and Strodex™), enable coatings manufacturers to formulate water-based products with customized rheology profiles that included creamy in-can feel, best-in-class spatter resistance, excellent color reproduction, sag resistance and leveling capabilities. With the addition of ISP, the opportunity emerges to bring a much broader portfolio of additive technologies to our customers. The performance polymers from ISP for coatings include supplemental rheology modifier chemistries as well as other technologies that can provide UV stability and help disperse and stabilize color and intensity. In addition, the ISP biocide portfolio brings a completely new functional category to the Ashland portfolio, including both in-can and dry-film preservatives for the prevention of fungus, mold and mildew. The combined portfolio also includes numerous products for wood coatings that include UV protection, color stabilization and rheology. Expanded access to this new market segment is exciting for Ashland, and we will be working to communicate our full portfolio of products and benefits to more customers and market segments in the coming months. You can see how expanding our offering beyond rheology, foam control and surfactants makes for a broader and powerful combination of benefits for our customers. Panichella 52



OCTOBER 2011 | W W W . P C I M A G . C O M

Will any new technologies be brought to the table as a result of the acquisition?

PCI:

What does the acquisition mean for coatings formulators?

This acquisition brings together two complementary technology portfolios that can be offered from a single supplier. For formulators, this means they will have fewer key supplier partners to manage and the convenience of finding formulating solutions faster and easier, by dealing with a single technical organization. We look forward to arranging technical seminars and exchanges with our customers wherein we can demonstrate our expanded array of technical expertise and capabilities. From a customer perspective, this will really be powerful.

PCI:

Availability of products…will you increase or decrease production?

Panichella: There should be no disruption of products or services as we integrate the two organizations. There is very little overlap in products and services. Together ISP and Ashland truly balance and supplement the overall product offering. PCI:

How will customers buy ISP or Ashland products?

Panichella:

There are no immediate changes in any of our current business activities, processes or relationships. Customers will continue to work with the same sales, service and support on whom they have always depended; and the selling legal entity with whom they do business will remain the same. All products, product names/ codes/brand names, packaging, labeling, MSDS, pricing, etc. will be unchanged. No changes are being made to manufacturing locations, manufacturing processes or product quality, nor will there be any changes in the addresses on quality documentation such as Certificates of Analyses, specifications, etc. For normal business or emergencies, current contact points, offices, addresses, telephone numbers, etc. are still valid. Ordering, delivery and invoicing processes, including documentation, do not change.

trategic sourcing has historically been a focus at very large, complex enterprises. Today, this is a process that can be implemented at an organization of any size. Oftentimes the stated goal of strategic sourcing is to reduce cost. This should not be the only goal, but rather one in conjunction with risk reduction, improving quality, fostering innovation, etc. Strategic sourcing is a term that continues to increase in popularity. Penned in the 1980s, this is a phrase that today results in more than three million results in online searches. It is the focus of a vast number of blogs, newsletters, tweets, etc. A cottage consulting industry has been spawned, and universities are beginning to incorporate strategic sourcing into their graduate school curriculums. This article will outline the strategic sourcing process and discuss the impact that a distributor can make.

Strategic Sourcing Process For the purposes of this article, the stages of the strategic sourcing process are as follows.

Market Analysis • • • •

Who are they key suppliers by product category? What are the key drivers? Do any geographic constraints exist? What macroeconomic factors, if any, may impact supply?

Vendor Analysis • Create supplier profiles. • Categorize current suppliers. • Identify suitable suppliers for each key product/service category. • Reduce risk by having knowledge of supply chain and establishing multiple sources for key materials. • Understand suppliers’ production and technical capabilities. • What metrics should be required from suppliers (ontime delivery performance, quality ratings, innovation, price stability, etc.)? • What quality standards are required – ISO, NACD, etc.?

Cost Analysis Assessment of Current Competencies • Evaluate your core supply chain competencies to identify what you do well, uncover weaknesses that can be improved on, and highlight areas that you need to implement. • How does your current supplier base perform? • Establish a baseline of where you are at today. • Evaluate the structure of your procurement functions – are they effectively aligned with your supply base?

“What gets measured, gets managed.” – Peter Drucker

• What do you spend for key product/service categories? • What is the cost of stock outs, shortages, etc.? • What is the impact of currency due to location of key suppliers? • Are your costs and required service levels aligned? • Working capital.

Logistics Networks and Internal Operations • Gain a broader understanding of the complete logistics chain. • Packaging/handling requirements and their impact on operations. • Environmental footprint. • Where are you at risk?

Develop a Strategy • What is the goal? • What is the time frame for implementation? • Is your sourcing strategy aligned with your corporate strategies? For example, does this assist with your geographic expansion? • Identify the priority items that can make immediate and long-term impacts on your business. • Work closely with suppliers to understand their capabilities and make sure they can meet your needs today and in the future. • Identify tangible, measurable results.

Negotiation • Meet with key suppliers to review your objectives and time frames. • What is the cost/service tradeoff? • Establish contractual pricing. • Who will collaborate with you to meet your goals? • Leverage relationships as you consolidate your base of suppliers.

transparency of the supply chain, and product bundling.

Global Sourcing Having access to raw materials globally and a fundamental understanding of the key stakeholders in your supply

chain will not only allow you to better understand the complexity of your supply chain, but will also increase your awareness of the important raw material price drivers. Distributors oftentimes do not want to disclose where they source products, as they are afraid that cus-

Execution • Cross-functional approach. Strive to get departments working closely together toward a common goal by limiting silo mentality. • Focus your resources on the most important categories. • Appoint a sole champion of the program.

Accelerate the damaging effects of sunlight, moisture & high temperatures.

Monitor Results • Communicate regularly internally and externally. • Make results visible. • Make adjustment as necessary based on results.

How Can a Distributor Impact Strategic Sourcing? As noted in the PCI article, Distributors Play a Critical Role in the Supply Chain, from the September 2008 issue, distributors provide value to customers in the following areas: • • • • •

Quicker order processing; Flexible payment terms; Global sourcing; Product bundling; and Close relationships.

Specifically relating to the strategic sourcing process, a few key components that may help achieve your objectives are global sourcing with full

Strategic Sourcing

tomers will begin to purchase directly, and ultimately cut out the distributor. With regard to specialty chemicals, we have found that this approach is short sighted and ultimately hampers our ability to cost effectively meet our customers’ requirements. A distributor relationship based on transparency, where our cus-

tomer knows the manufacturer, has the ability to audit their facilities, understands the production capacities, sees where key intermediates are sourced, etc., is one that allows the three parties to work collaboratively to meet each other’s objectives. The relationship has to be a win – win – win for this to be a long-term

success, and is not something that can be developed overnight (Figure 1). From a manufacturer’s standpoint, this type of relationship is beneficial, as they have an avenue for unfiltered market knowledge by having direct access to the customers’ technical, purchasing, operations and management staffs. Some tangible results for a customer are that they will form closer professional relationships with the manufacturer, which may provide access to new product launches sooner, and may increase the likelihood of obtaining product in times of shortage.

As part of the vendor management stage of strategic sourcing, having a strong relationship with regional distributors may allow you to reduce your overall number of suppliers. Distributors typically offer a wide range of complementary products, which allows customers to buy several items while reducing logistics and administrative costs. Furthermore, with a smaller number of suppliers, you will have time to focus on those partners that will assist in achieving your goals. You will be able to invest the time and energy in furthering the relationship and better understanding their operation, strategies and objectives.

Conclusion A fundamentally sound strategic sourcing strategy will be a differentiating factor for your business and will assist in achieving your corporate goals. By implementing the process, you will uncover opportunities for improvement, identify risk and gain a better understanding of your key suppliers. This process is not one that should be conceived as a one-time occurrence but rather one that develops into the foundation of your supply chain management.

Why Maroon? Customers often ask, "Why should we partner with a specialty chemical supplier like Maroon Inc., when we can buy from a multinational, global supplier?" There are several advantages that our clients can realize by partnering with Maroon. Listed below are just a few:

Flexibility Maroon Inc. can typically offer a greater level of flexibility than most specialty chemical suppliers. This includes lightning-fast turnaround times on orders, often in as little as two hours. With just-in-time manufacturing principles in place at many customers’ facilities and everchanging production schedules, we can meet your needs for immediate product delivery. This flexibility also includes custom labeling, packaging and consignment programs that allow our customers to focus on what they do best. There is no need for our clients to tie up their working capital with large amounts of inventory, when they can release what they need from Maroon on a daily or weekly basis.

Product Bundling From a specialty chemical sourcing standpoint, we can greatly reduce the risk for our customers. We have the experience and infrastructure necessary to identify, qualify, audit, manage international logistics and maintain supply relationships for materials that may not be accessible to you otherwise. This allows us to offer you a wide range of complementary products that far exceeds that of most specialty chemical suppliers. We can bundle these products together to reduce costs, positioning you to be more competitive in your markets.

Maroon Inc. has responded to the globalization of the chemical industry by taking an active role in fostering relationships around the world. Today, more than 50% of our sales are generated from international sources. That's up from less than 10% fifteen years ago. We realize the competitive nature of today's global economy and the importance of continually bringing value to our customers. That is why every day we work to identify new sources of raw materials, challenge our staff to find smarter solutions, and work at reducing costs. These are three key advantages that support the main goal of our business. Creating Customer Success® is a philosophy that was developed by our founder, Anthony Maroon. Tony felt that if we are able to help our customers achieve success, this would, over time, lead to the success of Maroon Inc. More than three decades later, this philosophy is still the driving force in our daily operations. Every Maroon Inc. employee is empowered to do whatever necessary to meet our customers’ requirements. By offering world-class products and service, and creative technical solutions, Maroon Inc. strives to create success for our customers. We personally audit facilities, demand that our partners maintain ISO certification, provide SPC data, and maintain liability insurance, all of which reduce risk for our customers. At Maroon Inc., the strength of our company is based on the relationships we establish and maintain with our customers, as well as the value of the solutions we provide. More than 50% of our customers have continued doing business with Maroon Inc. for 10 years or more. We take great pride in this statistic, as well as the relationships that substantiates it. "Maroon can move at a velocity unmatched by most multinational specialty chemical manufacturers." Specialty chemicals and packaging by Maroon Inc.
