Someone joked with me recently that it’s difficult to concentrate on green when there’s so much white outside. I’m located in Ohio, and my daughter’s school used up all of its snow days before Christmas—yet the flaky stuff just keeps coming down, and I know that other regions have been hit even harder. Luckily, green development programs and other sustainability-related efforts aren’t actually restricted by the weather! In fact, I feel privileged to be working with an industry that is actively involved in making the environment safer for future generations. Green chemicals and formulations provide the foundation that helps ensure that our products adhere to increasingly strict regulations while meeting sustainability goals and providing additional benefits to boot. For example, a new additive provides optimum performance characteristics while being volatile organic compound (VOC)-, hazardous air pollutant (HAP)- and alkyl phenol ethoxylate (APE)-free. Learn more in “A Green Substrate Wetting Alternative” on pp. 17-19. Polyether-based sealants and adhesives are becoming increasingly popular with architects and contractors due to their low VOC content. These no-solvent products eliminate shrinkage while helping building projects meet various regulations. Additional details are available in “A New Building Standard,” pp. 28-29. In this issue, we also spotlight programs and applications that help the environment. For example, Kraft Foods’ new agreement with Henkel and Adhesives Systems Inc. is expected to result in multiple social, economic, and environmental benefits. Read “Initiative Supports Diversity, Drives Efficiency” on pp. 21-24 to find out more. And “Pollution Prevention” (pp. 30-34) details a new hard surface composite paving system that uses post-consumer recycled glass to address the multiple environmental problems that can be caused by stormwater runoff. We’re always interested in hearing about your green developments. Please feel free to contact me at (330) 336-4098 or [email protected] to share your story.

2011 SPRING CONVENTION & EXPO APRIL 17-19 | TAMPA MARRIOTT WATERSIDE HOTEL & MARINA | TAMPA, FLORIDA

Featuring These Dynamic Keynote Speakers:

DR. KEN MAYLAND President, ClearView Economics, LLC As the recovery approaches its second birthday (June 2011), economic growth can at best be described as tepid. What headwinds have slowed the bounce back of business, and will they lighten up in the future, allowing for a more vigorous expansion? Will last year’s new stimulus package be offset and negated by spending cuts? How will all this shake out for production (by industry), pricing and foreign trade? All good questions— but you must attend to hear the answers!

MAURY ZIMRING Manager, Corporate Responsibility and Sustainability, Coca-Cola Refreshments Coca-Cola has been a leader in the environmental sustainability space, focusing on carbon reductions, water stewardship and sustainable packaging. The program will review the environmental sustainability agenda Coca-Cola has been pursuing in North America. It will highlight the work to-date, case studies of new technologies and processes and plans for the future.

DR. DAVID CROWE Chief Economist, National Association of Home Builders Hear what NAHB’s chief economist and forecaster thinks about the outlook for the housing industry, one of the largest market segments ASC members sell into. This session will drill down into this critical sector and complement the macroeconomic overview presented in Monday’s keynote session.

TIMELY EDUCATIONAL SESSIONS WILL ADDRESS THESE KEY INDUSTRY TOPICS: • • • • •

Feedstock Trends and Raw Materials Advancements in Formulation Research & Testing Small Business Issues Adhesives & Sealants in a Global Marketplace

News for the Industry February 2011 ADDITIVES 101 WEBINAR SERIES BEGINS FEBRUARY 16 On February 16, 23 and March 9, ASC is offering a three-part webinar series entitled “Additives & Formulating 101.” ASC has assembled a panel of additives experts to provide a thorough review of the raw materials that go into today’s additives. However, this is more than just a condensed version of the technical short course. An exciting new segment has been added to enhance the practical application. The last session will explore the basics of formulating and how to design an effective and efficient experiment protocol. Learn more and register at www.ascouncil.org.

ASC LAUNCHES NEW MEMBER DIRECTORY ON ADHESIVES.ORG To better connect the design-engineering community with ASC member companies, an improved, interactive member directory was launched in January. The new, consolidated directory is a significant enhancement over the previous manufacturer and supplier directories, and now includes all categories of ASC members. The designengineering community will benefit from user-friendly site navigation, based on market segments and product types, as well as a new search function. ASC member companies benefit from more exposure to end users looking for adhesive and sealant solutions. Visit Adhesives.org today to explore the new ASC member directory.

DISCOVER HOT MELTS IN ASC’S SHORT COURSE Hot-melt adhesives are often unique formulations created to meet specific customer needs with respect to handling, performance and application methods. As a result, many options and variations exist. ASC’s Hot Melts Short Course provides an in depth examination of these adhesives, making it an essential tool for chemists, engineers and other technical personnel as well as sales and marketing professionals who want to better answer customer questions and offer custom-tailored solutions. The Hot Melts Short Course will be co-located at the ASC 2011 Spring Convention & EXPO in Tampa on April 17 and 18. Complete details and registration information can be found on ASC’s website.

BACK BY POPULAR DEMAND: ADHESIVES 101 RETURNS MAY 11 To help nontechnical individuals build a good foundation of adhesive knowledge, The ChemQuest Group and ASC are once again offering the Adhesives 101 webinar series. Based on the North American Adhesive Bonding Professional Training Course, this three-part webinar will be held on May 11, 18 and 25. The course will cover adhesive markets, the science of adhesion, surface treatment, structural and nonstructural adhesives and proper joint design. Participants will better understand the science behind different adhesive technologies and the benefits adhesives bring to specific applications. Learn how to maximize the many advantages adhesives offer by attending the 2011 Adhesives 101 course.

SCALED BACK CALIFORNIA GREEN CHEMISTRY INITIATIVE GOES INTO EFFECT With the passage of the January 1 deadline, it appears that the California Green Chemistry Initiative (GCI) has gone into effect under a significantly narrowed scope from its original proposal, which is good news for the adhesive and sealant industry. The California Department of Toxic Substances’ (DTSC) final proposal (November 2010) aided adhesive and sealant manufacturers by narrowing the definition of a consumer product. For the next five years, DTSC will focus on personal care and cleaning products as well as products used by children under the age of 12. However, after January 1, 2016, there will be no limitation or specification of the type of product that could be identified as a priority product. Other areas of revision included a more limited definition for de minimis, with the recognition that 0.1% is an appropriate and necessary default value. In effect, this eliminated nano materials from consideration under the rule. For the latest regulatory information, visit the “Government Relations” area of the ASC website.

JOIN ASC IN CHICAGO TO DEFINE “GREEN” Sustainability is a continually-emerging trend in the adhesive and sealant industry. On this important issue, ASC stands ready to guide and support the industry it serves, but it will take the collective efforts of many individuals to come together to fully define what green means for the entire adhesive and sealant supply chain. To facilitate the exchange of information on this topic, ASC will be hosting a Sustainability Summit on July 26 and 27 at the Hyatt Regency O’Hare in Rosemont, IL. This event will convene industry stakeholders to discuss sustainability trends and open a dialogue about “What defines green?” in order to begin to establish metrics. It will take an industrywide effort to find answers to that question and position the industry for future growth, so mark your calendars to attend the inaugural Sustainability Summit. Visit www.ascouncil.org in the coming months for updates.

A LOT OF RECENT DISCUSSION HAS FOCUSED ON MAKING CONSTRUCTION ADHESIVES AND & SEALANTS GREEN BY ELIMINATING FORMALDEHYDE, PLASTICIZERS OR SOLVENTS. ARE THERE SIMILAR ALTERNATIVES FOR THE COATINGS THAT ARE OFTEN PLACED ON TOP OF THESE TYPES OF PRODUCTS? Green alternatives do exist for coatings as well. Building decision-makers often investigate the sustainability of macrocomponents of the built environment such as concrete, metal, wood and lighting. However, many intelligent methods are available that enable minor components such as coatings to greatly impact the overall sustainability of a structure by improving the indoor environmental quality, lighting efficiency, renewable content, graffiti resistance or long-term durability of major design components. Waterborne coatings products and plant-derived natural oil resins have gained in popularity due to increased environmental awareness and the polymer industry’s efforts to quantify the carbon footprint of many ubiquitous industrial, building, and construction products. For example, early water-based polyurethane coatings required the end user to compromise on physical properties, as compared to solventborne technologies. Now, high-performance, twocomponent waterborne (2K WB) polyurethane coatings are offered that meet or exceed the durability and weatherability of their old solventborne analogs while touting less than 10 g/L in volatile organic compounds (VOCs) and very low odor. Similarly, many natural oil polyol (NOP) resins or additives were used to supplant their petroleum counterparts but often compromised at least some of the desirable traits needed for the final end-use application. Current NOP-based floor coating technologies are being commercially installed that have > 35% renewable content, high durability, no VOCs or solvents, low odor, and no plasticizers or heavy metal catalysts. These types of coatings can contribute to a winning hand when an architect, engineer or building owner is designing with a focus on sustainability and green building practices. – Steven Reinstadtler

OUR COMPANY FILLS EXPANSION JOINTS IN CONCRETE FLOORS WITH AN EPOXY CAULK BEFORE & APPLYING A FLOOR COATING. THE EPOXY CAULK MUST BE HEATED WITH A TORCH BEFORE CUTTING THE MATERIAL FLUSH WITH THE CONCRETE. WE HAVE HEARD THAT POLYUREA SEALANTS DO NOT REQUIRE PREHEATING BEFORE CUTTING. CAN YOU EXPLAIN THE ADVANTAGES AND DISADVANTAGES OF THE DIFFERENT TECHNOLOGIES?

Expansion joints in concrete are often filled with a moderately hard resin to reinforce the edge of the joint, to create a flat surface for subsequent coating, to prevent liquids from draining into the joint, and to improve safety. Many years ago, these joints were filled with a two-component epoxy resin system. The epoxy resin had a long gel time and cured to a very hard, brittle, lowelongation material. Because of the epoxy system’s long gel time, the excess resin was often cut flush with the concrete the next day. Heating of the epoxy resin with a torch was often required to soften the material before cutting. The epoxy resin’s cure rate also varies depending on the ambient temperature. Today, polyurea sealants are often used to fill joints in concrete. The two-component (1:1 by volume ratio) polyurea technology has many processing and productivity advantages, including fast cure rate, fast gel time, moisture insensitivity, and the ability to cure at a low temperature. The fast gel time and fast cure rate allow polyurea sealants to be cut flush with the concrete in around 20 minutes. Polyurea technology is also used in low-temperature applications where other technologies will not cure. Cured polyurea sealants feature exceptional physical properties. Polyurea sealants have the required hardness and strength to protect the joint, but they also incorporate flexibility, high elongation and good adhesion to concrete. The original versions of the polyurea sealants are based on aromatic diphenyl methane diisocyanate (MDI). These aromatic resins typically discolor over time. Newer versions of the sealants use low-monomer-content aliphatic diisocyanate prepolymers and have dramatically improved UV resistance. – Jay A. Johnston, Ph.D.

meets ANSI-HPVA HP-1-2004 Type II and ANSI/HPVA EF 2009 testing for water resistance on most wood species. Soy extends the open time of this adhesive, making it ideal for use in prepress operations. Multibond MX-100 can go from the prepress to the hot press without the need for special mixing equipment. The parts come out of the prepress very tacky with the product. Multibond MX-100 also has demonstrated easy handling in a variety of climate conditions. Multibond MX-200 performs well in immediate (direct-feed) hot press laminating operations that do not have a prepress. Like MX-100, it cannot be cold pressed. Formulated with bleedthrough resistance, it is a fast, easy-to-use adhesive.

GREEN DEVELOPMENT

FRANKLIN LAUNCHES BIO-MODIFIED ADHESIVES New high-performance, bio-modified adhesives have been developed for use in the manufacture of engineered hardwood flooring.

Franklin Adhesives & Polymers has been active in the development of environmentally safe products for decades, and offers a full line of adhesives to meet CARB and other global formaldehyde emissions standards. The division pursued soybean research because it is a renewable resource that reduces reliability on petrochemicals, extends open times, is free of formaldehyde and offers physical flexibility. “We are grateful to the USB for its role in supporting research that led to the development of these adhesives and future products that use soy,” said Michelle Tobbe, wood adhesives technical director. “I think our customers will agree that we have developed the ideal blend of synthetic and natural materials to create environmentally friendly, cost-effective adhesives that are easy to use and perform very well.” For more information, phone Franklin Adhesives & Polymers at (800) 877-4583, e-mail [email protected] or visit www.franklinadhesivesandpolymers.com.

ABOUT FRANKLIN INTERNATIONAL Based in Columbus, OH, Franklin International was established in 1935 and is among the largest privately held manufacturers of adhesives, sealants, and polymers for commercial and industrial applications. Franklin integrates its core competency—emulsion polymerization—into a broad product offering, including glues, adhesives, binders, films, sizing compounds and more. These products are distributed across six continents for use in construction, furniture manufacturing, millwork, filters, pressure-sensitive paper products and fiberglass reinforcement.

hrough research made possible via a grant from the United Soybean Board (USB), Franklin Adhesives & Polymers has developed two bio-modified adhesives. The Franklin International division incorporated a soy derivative into polyvinyl acetate (PVA) to create high-performance, bio-modified adhesives for use in the manufacture of engineered hardwood flooring (hardwood plywood).

A GREEN SUBSTRATE WETTING ALTERNATIVE A new additive offers optimum substrate wetting performance while enabling the formulation of low-VOC aqueous adhesives products.

By Peter Sheridan, Director–Performance Additives, Troy Corp.

r o y C o r p . ’s m u l t i f u n c t i o n a l Troysol™ LAC provides excellent wetting of low-energy and contaminated surfaces, resulting in strong adhesive bonding. However, due to government regulations and consumer demand for environmentally compliant, green products, the c o m p a n y h a s i n t r o d u c e d Tr o y s o l ZLAC to fill the gap. ZLAC is a zerovolatile organic compound (VO C), hazardous air pollutants (HAPs)free, alkyl phenol ethoxylate (APE)free version of the traditional LAC product. ZLAC offers the same optimum substrate wetting performance as traditional LAC, but also enables the formulation of low-VOC aqueous adhesives products.

T

Figure 1. Troysol ZLAC Enables Complete Wetting over Low-Energy Substrates

ENHANCING PERFORMANCE Complete substrate wetting must occur in order to obtain a strong adhesive bond. Effective wetting additives reduce the surface tension of the adhesive, enabling complete coverage of the substrate. Effective wetting additives are especially important for lowenergy surfaces, which would otherwise resist coverage. In addition, if a substrate is contaminated, low-energy contaminant particles repel the adhesive, resulting in surface defects and a weakened bond. When an effective wetting additive is present, adhesives will wet any contaminants and/or low-energy substrates, thus creating a strong, unimpeded bond. February 2011

ADVANCING ADHESIVES

REDUCING SURFACE TENSION High surface tension makes water inherently poor at wetting most substrates. A good example of this high surface tension is when a metal pin floats on the surface of water. Troysol ZLAC was first evaluated for its ability to reduce surface tension, which is essential to enable complete wetting over low-energy substrates. Figure 1 (p. 17) shows how ZLAC was able to reduce the surface tension of water with use levels as low as 0.1%. Table 1 lists the surface tension values of typical solvents used in adhesives formulations. Conventional adhesive technology is based on solvents with l o w s u r f a c e t e n s i o n s . C o n v e r s e l y, aqueous adhesives require wetting additives to reduce the surface tension. The use of wetting additives enhances the coverage of substrates with low surface energy (see Table 2). An adhesive with a high surface tension in the liquid phase will have poor wetting over low-energy substrates, resulting in craters and/ or severe crawling. Troysol ZLAC, h o w e v e r, e f f e c t i v e l y r e d u c e s t h e surface tension of water to 25 dynes/ cm, enabling aqueous adhesives to spread over low-energy substrates. Figure 2 (p. 17) shows a wetting test over a siliconized film. The formulation containing ZLAC provides complete coverage, while another formulation containing ethoxylated acetylenic diol, a commonly used wetting additive, showed severe crawling at equal concentrations.

PEEL STRENGTH TEST Peel strength tests are valuable for determining the strength of the adhesive bond between two materials. In order to evaluate the adhesive strength imparted by the wetting performance of Troysol ZLAC and LAC, peel strength tests were performed using three typical pressure-sensitive adhesive (PSA) formulations (see sidebar). The following procedure was used for peel strength evaluation (180˚ Peel by PSTC 101 Test Method D): 18

ZLAC was also evaluated separately at very low use levels, from 0.05-0.2% (weight additive based on total formulation), in formulations A, B, and C to determine the lowest concentrations at which maximum peel strength was obtained.

Figure 3. 180° Peel Strength of PSA Formulation A

RESULTS AND CONCLUSIONS Test data show that substrate wetting imparted by Troysol ZLAC increases the peel strength in PSAs, and is the equivalent of the optimized performance offered by the traditional LAC product (see Figures 3 and 4). Both additives enhanced substrate wetting and increased peel strength, thereby imparting greater adhesive bonding and better film integrity. In addition, concentrations as low as 0.05-0.1% ZLAC provided a substantial increase in adhesion for formulations A, B and C (see Figure 5). The use of zero-VOC Troysol ZLAC wetting additive has shown excellent substrate wetting efficacy equivalent to that of Troysol LAC when used in PSAs applied over low-energy substrates. ZLAC can help formulators achieve defect-free films with excellent surface appearance and optimum adhesion performance, without VOC contribution.

“The alliance was formed to provide the best of both organizations to companies like Kraft that want to increase their spending with minority-owned companies while at the same time accessing a broad range of adhesive products, highlevel technical support and a footprint that would serve them wherever they have plants,” explains Jerry Perkins, senior vice president and general manager of Henkel’s Industrial Adhesives business. “The combination of our two companies created that kind of offering.” According to George Hill, chairman and CEO of ASI, “We both have technology and laboratories, and create products. We’re two separate companies, each with our own portfolio of products and each with our own R&D efforts. But it’s a collaborative effort. Henkel has more products than we do, and we needed a global partner.” The Henkel-ASI alliance includes established protocols for entering into distribution, license and other agreements that will enable ASI to manufacture and/or distribute certain Henkel products while receiving technical and other support from Henkel. Hill says that the alliance is exciting because it allows ASI to expand its reach in terms of products and geography. “There is no question that to be aligned with Henkel with their capabilities in terms of products, leverage, size and experience is almost a perfect synergistic relationship,” he says. “Their size and reach coupled with our agility and innovation is a perfect marriage.” Hill and Perkins both point out that ASI is and remains a competitor of Henkel and its predecessor, National Starch and Chemical. “We had customers who knew what both companies were capable of,” says Hill. “What many didn’t know was the scope, scale and vision that this alliance could have.”

RECOGNIZING THE POTENTIAL “Kraft has a strategic interest in growing their diversity spend and improving their purchasing and supply chain activities, and all three companies realized that the alliance was a good fit,” Perkins says. 22

Hill agrees. “The value system embodied in this initiative is a loop in which all parties have a philosophy and experience with diversity that contributes,” he says. “The relationship between the three companies has developed with time and trust.” The scale of the proposed agreement with Kraft Foods will be significant and is expected to go well beyond simple diversity spend to deliver significant procurement and production efficiencies. “One of the things ASI and Henkel do in serving our customers is to help them simplify the portfolio of adhesives they buy,” Perkins says. “When you consider the diversity of packages, it’s an enormous sea of packaging concepts. There is a lot of innovation, a lot of development, and lot of new demands on the components that go into the packaging, whether it is films and different paper substrates or the adhesives themselves. So the adhesive category is very fragmented, and some of our customers buy far too many adhesives. Their adhesive portfolio is too complex. Most of our customers are very keen on having us help them technically reduce that complexity.” “Not only will we reduce the complexity of their supply chain, we will reduce the number of adhesives they use,” says Hill. “Kraft Foods probably uses 80 or 100 adhesives, and we are confident we can reduce that by 70-80%.”

COMBINING CONSISTENCY AND INNOVATION Perkins points out that implementing a harmonized and simplified adhesive product line will provide additional benefits. “Kraft Foods will get consistency and enhanced quality,” he says. “A second dimension is innovation. Kraft Foods wants ongoing innovation for their packaging, and they want an adhesive supplier that can support their objectives in that area. We will deliver innovative new adhesive technologies that allow Kraft Foods to introduce new packages that are stronger in terms of consumer convenience, functionality and waste reduction. A lot of the technology we will implement for Kraft, such as our lower temperature adhesives, consume far less energy, and that too has great appeal to Kraft.” February 2011

Of course, Kraft Foods has very stringent demands with respect to the packages it produces, which represent its brands prominently on the shelf. “Kraft demands that its packages maintain or enhance the equity of its brands,” says Perkins. “We can help them with a strong technical adhesive alliance in taking an overly complex adhesive portfolio and paring it down to exactly what they need. When we do that, they will reap all kinds of efficiencies.” According to Hill, that is only the beginning. “The initiative opens an entire array of additional opportunities for Kraft, Henkel and ASI,” he says. “We will be involved with Kraft business units in a way that will bring great value to their supply chain.” Hill pointed out that adhesives are normally the last consideration in the packaging process, and they are the least expensive in terms of percentage expenditure on the package itself. “But just think what happens when you coordinate the corrugated suppliers and the carton suppliers and the contract manufacturers and the suppliers upstream doing work on flexible packaging and pressure-sensitive applications. The synergy between adhesives and all the other factors—the equipment, the substrates, the carton and packaging suppliers—becomes dynamic.” “Of all the supply chain partners, we are the last thing that goes in the package before it goes out the door,” Hill continues. “So our involvement and insight into all those factors is invaluable in reducing costs and improving e f f i c i e n c i e s . We ’ r e t a l k i n g a b o u t innovations in developing new products, productivity in terms of the number of cases and cartons, cans of coffee, bars of candy, or whatever coming through the system. Certainly we’ll reduce simple transaction costs and suppliers, but it’s a much bigger picture than that.”

THE STRENGTH TO IMPLEMENT CHANGE Implementing such far-reaching change takes technical expertise and global strength. Kraft Foods’ machinery will have to be factored in, because, depending on the packaging type and the plant, a variety of machines will be running. “It’s not a simple challenge to take one adhesive and implement it in multiple plants, multiple packaging formats,” says Perkins. “We have to be very competent technically, and that’s one of the things Kraft Foods is expecting from the alliFebruary 2011

ance. We have to do a detailed technical assessment up front to ensure that when we tell Kraft a particular adhesive will run on this line or in that plant, it will. They know we have a lot of feet on the street, a competent technical organization, and the ability to assist their plants in simplifying their processes around the adhesives they use. Equally important, they know we can do it seamlessly without any impact on their operation.”

For Kraft Foods, the proposed agreement will support multiple strategic objectives. “Kraft Foods is committed to doing its part to ensure that we have a diverse workforce and supplier base, be a good steward of the environment, improve our communities, and deliver value to shareholders,” says Julia Brown, senior vice president of Procurement at Kraft Foods. “We believe this initiative with ASI and Henkel will deliver significantly against these commitments.”

INITIATIVE SUPPORTS DIVERSITY, DRIVES EFFICIENCY The incremental volume from the project with Kraft Foods in North America will allow the ASI-Henkel alliance to bring capital investments and jobs (both technical and administrative) to the Detroit metro area, the hard-hit labor surplus area where ASI is located. “The impact on our company and our community will be substantial,” says Hill. “We will make capital investments and investment in hiring people. We’ll put on a third shift, buy more equipment.

We will create employment in a city that sorely needs it.” In fact, ASI has already invested about $350,000-400,000 to expand production levels in their adhesive plant and will expand it even further. “I think it’s safe to say that over the next several years, our investment will be seven figures,” said Hill.

problem in Michigan,” continues Hill. “But it does present an answer in terms of the way partnerships can come about and the impact they can have on the community. Our hope is that other companies will see value in this model.” According to Perkins, “The commitment to diversity was one of the key drivers behind the 2008 formation of the ASI-Henkel alliance. The alliance has already been well-received by a number of major consumer-goods companies, and this commitment from Kraft Foods demonstrates the value that ASI and Henkel can bring to the market. At Henkel, we are very excited about the opportunity to work with the Kraft Foods team to bring this grand vision to reality.” The scope of this project is a testament to Kraft Foods’ broader commitment to diversity, as the company has invested in supplier diversity for more than 25 years. It is likely that other consumer product manufacturers will support the ASIHenkel alliance and further affirm the industry’s commitment to diversity. Hill says that, when it comes to a bold vision that accomplishes great value for the customer and an incredible level of diverse supplier development, Kraft Foods is clearly a change agent. “By harnessing the agility and experience of a 15-year minority supplier like ASI and the scale and technology of a global supplier like Henkel, they have formed a strategic alliance that will have an enormous impact.” According to Perkins, the decision of global food giant Kraft Foods to join forces with the alliance is a pioneering step. “Although they are not the first company to partner with our alliance, Kraft Foods is the first company to take the alliance to the level in which we are aligned with their strategic objectives. We anticipate that they will be the first of several consumer packaged goods manufacturers to benefit from this kind of commitment.” “We know it will work because it’s already working,” adds Hill. “The initiative between Kraft Foods, ASI and Henkel means growth and jobs in an ethnically diverse community. And it sets an example that corporate America can repeat across other kinds of products in other minority companies.” For additional details, visit the companies’ websites at www.kraftfoodscompany.com, www. diversifiedchemicalinc.com/adhesive.html or www. henkel.com.

TURBOCHARGING GREEN INTO PACKAGING ADHESIVES A new technology in packaging adhesives reduces overall consumption and improves efficiency. By Mike Jorgenson, President, Liquid Polymer

reating greener adhesives is a hot topic in today’s industry. Many manufacturers are taking action to improve the sustainability of their products and lower their environmental impact. Reduction in consumption—whether through improved fuel mileage in our vehicles, improved adhesive mileage in our packaging systems, or the use of energysaving devices—is the most obvious and sustainable gain our society can strive to achieve. Adhesives manufacturers have approached this issue by modifying chemical structures and additives, while equipment manufacturers have sought to reduce consumption with complex stitching, swirl patterns, and foaming devices. To circumvent the challenges associated with hot-melt technology, cool-on-delivery/hot-on-demand Liquamelt ® technology aims to create greener alternatives in packaging adhesive technology. It targets a > 70% reduction of the carbon footprint while maintaining the same or better performance characteristics by combining: • Improved mileage obtained as a result of a water-blown, foamed adhesive process • An adhesive formulation manufactured with greater than 40% renewable raw materials • Delivery-point processing

C

THE ADHESIVE MECHANISM When Liquamelt was first commercially introduced in 2008, it offered customers a different method for packaging adhesives delivery: processing adhesive on demand, as required by the application. This technology produced a safe, room-temperature liquid that could replace traditional hot-melt delivery methods (which require extensive equipment, tanks, and hoses in order to heat large quantities of adhesive and maintain proper temperature). Instead of processing chemicals in large February 2011

Mileage is improved due to the waterblown, foamed adhesive process.

factories, shipping the solid pellets and remelting them, the TurboActivator™ serves as a “mini-factory” for processing the Liquamelt at the delivery point—where it is activated to form the working adhesive. See Figure 1 (p. 26). Meeting the adhesives and sealants industry’s goals of safety, convenience, and efficiency required the development of an adhesive with properties that allowed it to be a stable liquid at room temperature and rapidly transform into a thermoplastic on demand. Based on these criteria, this technology would ultimately require three essential components: • A liquid carrier component compatible with the adhesive system • A sponge component to soak up the liquid carrier when activated • A backbone component capable of creating superior structural integrity and adhesion This selection of components provided a product that is liquid, and—when activated by the TurboActivator—capable of bonding at speeds in the range of 0.3 seconds. It can also be applied to a variety of substrates. Adhesives & Sealants Industry

TURBOCHARGING GREEN INTO PACKAGING ADHESIVES The bonding mechanism in the Liquamelt system, which is used as the piece moves out of the compression stage, is very different from either hot melt or cold glue. Instead of sacrificing liquid in the bonding process (which is followed by subsequent crystallization), the parts are initially held together through viscoelastic forces, which then set up in a matter of seconds. Products held together out of the compression stage will gain strength and reliability over time as these bonds relax in fluctuations of temperature and humidity, thus virtually eliminating environmental pop-open problems that are experienced by other thermoplastic systems.

Figure 1. Liquamelt Process Overview

INCREASING THE GREEN FACTOR In addition to providing a 50% reduction in adhesive consumption, Liquamelt also replaces more than 40% of the raw materials with vegetable oils, reduces overall energy consumption, and minimizes handling costs. The result is a step-change improvement in the carbon footprint, producing a reduction of greater than 70%. Adhesive reduction is brought about by the use of foamed adhesives. The surface area covered by the adhesive bonding the two materials is generally proportional to the load-bearing properties of the assembled part. The most effective means of creating the greatest surface area is to develop a simple foamed adhesive system. This goal can be achieved by capitalizing on the properties of cool-on-delivery technology, which allows the Liquamelt to be formulated with an environmentally friendly blowing agent (i.e., water) and combined with hoton-demand delivery (i.e., TurboActivator) to simultaneously activate the blowing agent and adhesive. The combination of these technologies provides a low-density, high-surface-area adhesive at the point of application, resulting in an adhesive system capable of expanding up to 10 times its original volume, thus reducing adhesive consumption by half in a variety of sealing applications. The three components—liquid carrier, sponge and backbone—were evaluated for initial substitution with renewable raw materials. Since the liquid carrier was the largest component by percentage of weight, it was targeted as the first component to be converted. What was once based on petroleum-derived mineral oils could be converted to vegetable oil liquid carriers. This results in an adhesive that now comprises more than 40% sustainable materials. 26

Less packaging means easier transport. The cool-on-delivery technology allows the material to be transferred in 5-gal bag-in-box systems, drums and/or totes. The reduction of adhesive consumption obtained in the foaming process translates into environmental and cost benefits such as less packaging; lower weights for transport; and less handling, since a 50% increase in mileage means that 50% less material exists at each stage of the process. U s i n g t h i s t e c h n o l o g y, e n e r g y consumption is reduced on multiple levels. Instead of converting chemicals to hot melts in energy-intensive manufacturing scenarios, transporting twice as much material to the customers, and remelting

the pellets for dispensing, Liquamelt can be delivered, processed, and dispensed on demand, saving energy at each step. Depending on the customer’s operating protocol, the cool-on-delivery/hot-ondemand technology reduces the amount of energy consumed by more than 70% while eliminating the moving parts, heated tanks, and hoses needed in traditional hotmelt technology. The TurboActivator simultaneously serves as a high-efficiency heat exchanger and static mixer. It is enclosed in three layers of insulation, and its thermal cartridge heater is located in the center of the device. In this way, all of the energy transfers efficiently to the activation of the February 2011

Figure 3. Potential Applications

adhesive, producing energy savings from the point of manufacturing to the point of application. In addition, cool-on-delivery adhesives are capable of starting up in 3-10 minutes (vs. 30-60 minutes required by a hot-melt system). Moreover, the system’s ability to hibernate when inactive, as well as its low-energy delivery systems, provides additional savings in energy, depending on the mode of operation (see Figure 2).

PERFORMANCE ANALYSIS As in any industry, the challenge of creating greener packaging adhesives is to create alternatives that are not only environmentally sustainable but also capable of meeting the industry’s high standards. In the case of Liquamelt, the cool-ondelivery model is successfully operating in a variety of manual hand gun and highly automated systems. Because it is applied as a foam, zero- or reduced-cavity modules are generally the dispensing technology used for automatic systems. These liquid bulk feed systems eliminate the need for vacuum systems and can be located remotely, thus reducing the need for floor space, constant monitoring, and February 2011

refilling. Liquamelt is delivered at room temperature to the point of application via a standard hydraulic piston pump and hoses. This allows operations to feed multiple dispensing heads on multiple lines from a centralized adhesive source. Each system can be expanded from one to four channels by adding modular temperature controllers and TurboActivators. A fourchannel unit is capable of processing 35 lbs per hour, which equates to 70 lbs per hour of hot melt. Converting hot melt and hot melt/cold glue lines requires only the replacement of existing hot hoses and guns with TurboActivator and gun assemblies. The Liquamelt system can be up and running within 10 minutes of installation. Applications range from point-of-purchase, case and tray systems running at 30-70 units/minute to high-speed carton lines running as fast as 250 cartons/minute. Adhesive weights as low as 0.02 g have been obtained with a throughput capacity of 5-7 lbs per hour per channel. The use of the foamed adhesive technology has allowed these applications to realize mileage improvements of 30-70%.

With its HMIS rating of H:1 F:0 S:0 and its non-reactive composition, Liquamelt can be cleaned up with soap and water. Operators have discovered that the characteristics of the foamed polymer make post-activation cleanup easier than hot melt or cold glue. Instead of scraping or scrubbing packaging equipment, as is done for conventional lines, extraneous activated adhesive can be blown off with air or vacuumed up because it only adheres to targeted substrates. This feature has been shown to minimize maintenance and optimize line efficiency. Hot-melt systems are known for their potential to cause burns. Liquamelt only adheres to targeted substrates, making skin contact less hazardous. While it is strongly recommended that the same precautions taken for hot melts are also followed for activated Liquamelt, it has been discovered that serious burns can be avoided by rapidly brushing the adhesive from the contacted skin. Because the system is an adhesive foam expanded with steam, the latent heat in the bead allows it to have several seconds of open time while having sealing characteristics in tenths of seconds as the bubbles are compressed— releasing and condensing the steam. This characteristic has led to unusual application characteristics where the typical open time and bond time paradigms are broken, enabling Liquamelt to penetrate plastic and foam applications that often require more complex pressure-sensitive adhesives with elaborate swirl patterns to avoid melting the substrate foam and/or plastics. Figure 3 illustrates applications of the technology. The three-component adhesive system leads to a polymer structure that behaves like more advanced polymers, creating very strong bonds capable of withstanding temperature latitudes ranging from -40140°F. This allows customers to use a single adhesive for products that will experience both high- and low-temperature environments.

A GREEN FUTURE Despite hot melts’ stronghold on the packaging adhesive market, the outlook for alternatives such as cool-on-delivery/hoton-demand adhesives is bright. Driving the demand for greener packaging adhesives are end users’ needs for reduced costs, greater efficiency and optimum sustainability. For additional information, contact Liquid Polymer at 1909 N.

More U.S. building contractors are switching to polyether-based sealants and adhesives for performance, safety, and low VOCs.

Polyether-based sealants and adhesives are safer to use and better for the environment.

olyether-based sealants and adhesives, the advanced formulation polymers that have overtaken urethane and silicone products in Japan and Europe, are now becoming the new standard among U.S. architects and contractors for use throughout the entire building envelope—from foundation to roof. In the past year, the use of polyether-based sealants has nearly doubled for both new construction and repair work. The driving forces behind this increased popularity are the superior performance and environmental compliance characteristics of polyether-based sealants and adhesives, compared to many urethane- and silicone-type products. “Polyether-based adhesives and sealants are water-cured and contain no solvents,” explains engineering consultant Richard Boone, president of Construction Support Services in Centennial, CO. “Therefore, they have no shrinkage, possess excellent adhesion properties, and are very durable yet retain excellent flexibility.” Because these advanced sealants and adhesives contain no solvents, they produce very few volatile organic compounds (VOCs). In addition to the environmental benefit, this also makes polyether-based products compliant with increasingly stringent local and state VOC regulations. (VOCs are substances that evaporate into the atmosphere, contributing to climate change, chronic respiratory disorders and cancer. In

addition, many sealants that produce VOCs are flammable, produce irritating odors and tend to degrade over time.)

REWRITING THE BOOK Boone, a longtime engineer, specifier and compounder, chairs the committee that was chartered to develop an ASTM International standard for polyether-based sealing materials. He says that, although the initial acceptance of polyether-based adhesives and sealants was based on roof work, these products are now increasingly popular for joints, seams or laminations (including wall panels, windows, doors, pavements and countertops). “The polyether backbone, which is a long-chain hydrocarbon, is very stable,” explains Boone. “The long chain makes it inherently resistant to the effects of weather, so you don’t need to mix in a lot of other stabilizing chemicals to make it durable. The water-based cure system creates a very strong bond, so these polyether sealants and adhesives will adhere to virtually all surfaces. That property enables them to hold tight and makes them applicable to seams and joints throughout construction and repair projects.” Once a polyether-based sealant or adhesive is applied, it reacts with moisture in the air and crosslinks to form a February 2011

tough, long-lasting, flexible chain. It cures rapidly, adheres to a wide range of materials, meets the toughest standards for joint movement, won’t shrink and won’t suntan. Boone cites the work of Chem Link Advanced Architectural Products (Schoolcraft, MI) in developing and popularizing the use of polyether compounds throughout the U.S. Chem Link has developed of a variety of products that address assorted adhesive and sealant requirements throughout the building envelope. “Chem Link has taken a polymer that is known for having an excellent basis for adhesives and sealants and then created formulas that allow you to do an enormous amount of different tasks very well,” Boone explains. “By careful compounding and blending of different ingredients, the company has virtually rewritten the book, developing a range of products that offer distinct advantages for applications involving seams throughout the building structure.”

NO MORE SHRINKAGE “Our initial interest in polyether-based adhesives and sealants was the fact that they don’t shrink, as many solvent-based urethane and silicone products do,” says

Paul Graham of manufacturers’ rep firm Moore Graham Sales, Inc. in Granbury, TX. “If they shrink, they leak, because water simply runs behind the material. Of course, that causes major damage and other problems.” Polyether-based adhesives and sealants are cured by water they draw from the air, so there are no solvents to evaporate and cause shrinkage. Because these products cure from the top down and the bottom up, they are watertight and fairly durable within 10-20 minutes, though they typically take two to three weeks to completely cure. At this point, as Graham notes, they become hard as a hockey puck but remain “remarkably” flexible. “The material is also easy to work with, seals better, and lasts longer. We

have not had a single callback, which is notable in our industry,” he says.

THE POWER OF GREEN Graham adds that, although the polyether adhesives and sealants were initially popular because of their superior performance properties, the no-solvent chemistry has more recently added to sales. “The green aspect of the polyetherbased, one-part pro duct wasn’t so important in the past, but it is important now,” confirms Boone. “In the case of the Chem Link products, you’re using material that is 100% solid. You are dealing with no solvent release, almost no VOCs and no objectionable odors. You can safely work with these materials inside the building as well as outside.” Boone a dds tha t in using t hes e p r o d u c t s , c o n t r a c t o r s d o n ’t h a v e to worry about confined spaces, flammability or whether they will contaminate some other material. “These polyether-based materials are very safe for the person in the work environment, and they are ultimately safe for the building occupants both during and after construction,” he says.

An innovative hard surface composite paving system uses post-consumer recycled glass. By Steven Hicks, Market Development Manager, Urethane Specialties Business Group, BASF Corp.; David K. Bower, Senior Research Chemist, Urethanes R&D, BASF Corp.; and William G. Handlos, Business Director, Presto Products Co.

illions of gallons of untreated stormwater pollute our lakes, rivers and oceans every year. Conventional concrete and asphalt pavements concentrate these pollutants at the storm drains. Whether it is through a combined sanitary sewer system or a local detention pond, treatment is expensive. In most areas, the stormwater remains untreated, allowing the pollutants to flow directly into our waterways. The next time you walk across a street or through a parking lot, take a closer look around. You’ll probably see some solid waste like paper, food, bird droppings or animal feces, or possibly some fertilizer from a neighboring lawn. More than likely, there will be some stains from cars that have leaked oil, brake fluid, transmission fluid or antifreeze. What do you think will happen to these materials during the next rain? In all probability, they will end up in a storm drain that is discharged directly into a local lake, river or ocean. Recent studies have found that urban rainwater and snowmelt rivals (and in some cases exceeds) sewage plants and large factories as a source of damaging pollutants. 1 Storm water washing over impervious surfaces can pick up toxic chemicals, diseasecausing organisms, dirt and trash. Conventional hard-surface pavements concentrate these pollutants at the storm drains, thereby creating what the U.S. Environmental Protection Agency (EPA) considers a point source emission of pollutants. In most cases, stormwater is not treated because it is too expensive or impractical. A Filterpave ® porous pavement system can reduce or eliminate stormwater runoff from many areas and provides some unique benefits compared to impervious pavement or even other types of porous pavement. It is appropriate for parking areas, driveways, walkways, patios, golf cart paths and other light- to medium-duty traffic areas.

THE NEED Two hundred years of unmanaged urban stormwater have contributed to public health problems and expensive natural resource losses in the U.S. Left unregulated and uncontrolled, urban stormwater may: • Pollute drinking water sources, clogging reservoirs with silt and oxygen-depleting nutrients • Fill in navigable waterways with contaminated sediment, increasing dredging and disposal costs • Close or reduce lucrative rockfish, shad, flounder, crab, oyster, and other commercial fisheries due to chemical contamination and/or oxygen starvation resulting in loss of habitat • Foul beaches and other recreational waters, causing losses in revenues from declines in boating, fishing, water fowl hunting, and coastal tourism • Scour smaller stream channels and dump excessive gravel and silt loads that may affect fish and amphibian habitats • Change the hydrology of streams, springs and wetlands, affecting sources of clean surface and ground water • Damage homes and businesses during flash floods, which are more common where stormwater is left uncontrolled Each of these problems carries a significant cost, such as increased spending for health care, higher insurance or drinking water rates, declining stocks of commercial fish, and loss of tourism revenue.1 The most common ways of treating stormwater, either with a combined sanitary sewer system or the use of a detention pond, are expensive or can be problematic. In the case of a combined sanitary sewer system, an overloaded system during a heavy storm may send raw sewage directly into a local waterway. In other cases, it may cause untreated February 2011

waste water to flood homeowners’ basements. Each year in the U.S., thousands of homes are flooded in this manner, causing exposure to potentially deadly pathogens and creating conditions that could promote the growth of toxic black mold. Detention ponds use up valuable land resources and—if not managed properly—can become an eyesore, create nuisance odors, or become a breeding ground for insects. In response to these storm water management issues, local and state governments are creating new regulations to limit the amount of impervious area in new developments or preventing impervious expansion of buildings or hardscape in existing developments.

Figure 1. The Effect of Treating Glass Particles with Aminosilane on Compressive Strength of Filterpave

SYSTEM FEATURES Filterpave porous pavement system uses post-consumer recycled glass as the open-graded aggregate. According to the Container Recycling Institute (CRI), only 27.8% of glass bottles were recycled in the U.S. in 2006.2 Considering the number of municipal recycling programs around the country, and the fact that industry experts claim up to 70% recycled glass can be used to manufacture new containers (thus saving energy and improving efficiency), this is a surprising statistic. The problem lies with sorting glass from other solid waste materials and sorting the crushed glass cullet based on color. Glass manufacturing can only tolerate a small percentage of foreign matter or glass of the wrong color. Right now, almost all the glass people think they are recycling ends up in a landfill. Filterpave requires some additional processing of the glass cullet to make it suitable for use as the aggregate in the porous pavement. The cullet is tumbled or vibrated over screens to reduce or eliminate sharp edges. The material is sieved to obtain the correct particle size (approximately 0.12-0.25 in. in diameter). Then the glass is treated with a dilute solution of hydrolyzed aminosilane in water to develop a reactive surface on the glass for the polyurethane binder. The final steps are to dry and package the open-graded aggregate in waterproof super sacks to be used on the construction site. Figure 1 shows the improvement in compressive strength (approximately 40%) achieved by pretreating the glass with the aminosilane solution. In addition, it makes the composite pavement much more stable to environmental forces, such as heat and humidity, which could potentially reduce its strength and eventually cause failure of the pavement. Thermal cycling in high-humidity conditions shows little or no loss in compressive strength after 75 cycles between -10°C and 25°C. The two-component, MDI-based polyurethane (PUR) binder used for the Filterpave composite is a strong, elastic and extremely hydrophobic thermoset plastic. Table 1 (p. 33) shows the typical physical properties of the neat elastomer. The polyurethane contains over 50% renewable resource content in the form of natural oil-based components, which imparts the desired hydrophobicity that is often necessary for field applications. The chemical components of Filterpave PUR are similar to those of Elastocoast PUR, which has a proven track record for field use.3 The PUR provides consistent physical properties for the composite over a wide range of temperatures, as shown by the dynamic mechanical analysis (DMA) of the cured elastomer provided in Figure 2. The Filterpave PUR can be pigmented with a variety of colors, but five base colors were chosen (sapphire blue, jade green, sedona red, amber brown and topaz brown) to limit complexity within the supply chain (see Figure 3).

a standard white (reflectance 0.80, emittance 0.90) is 100. For example, the standard black has a temperature rise of 90°F (50°C) in full sun, and the standard white has a temperature rise of 14.6°F (8.1°C). Once the maximum temperature rise of a given material has been determined, the SRI can be computed by interpolating between the values for white and black.

SYSTEM BENEFITS

Filterpave pavement is open pore, which allows air and water to flow directly through the composite. Even though the pavement uses much smaller aggregate than more common porous pavements (i.e., pervious concrete and porous asphalt), the composite maintains over 35% void volume. This allows the material to accept very large volumes of water in a short period of time. Testing at the University of Central Florida indicates that the pavement can accept 1,600 in. of water per hour. Also, the void volume makes the maintenance of the open structure easier, because sediment deposited in the pores can be removed with little effort. Air flow through the material allows it to release heat through convection much more quickly than conventional pavements, so the pavement cools down in a much shorter period of time (compared to its alternatives) after a heat source is removed. The Solar Reflective Index (SRI) for the five colors of Filterpave is provided in Table 2 (ASTM E 1980 test method), along with some generally accepted values for concrete and asphalt. SRI is a measure of a surface’s ability to reject solar heat, as shown by a small temperature rise. It is defined so that a standard black (reflectance 0.05, emittance 0.90) is zero, and

The Filterpave porous pavement system mimics the natural filtration process that occurs when water flows through the ground. Organic contaminants that are deposited on the pavement can be trapped in the storage layer under the wearing course and decomposed by bacteria. This allows the local aquifer to be recharged with clean, filtered water. It also reduces the amount of impervious surface on a given site so that the land use can be more efficient in new developments. It may reduce the size of a detention pond or eliminate it all together. For developed real estate, porous pavement will reduce the amount of storm water that is sent to the local treatment facility, thereby alleviating stress on the system, or it may eliminate a potential point source emission for the untreated discharge to a local waterway. As long as the porosity is maintained in the pavement, it is very stable to freeze-thaw cycles. Ice will freeze through the composite to the point of least resistance. Consider the following analogy: if a capped glass-bottled beverage is placed in a freezer, the bottle will burst when it freezes; if the bottle is uncapped, the liquid will freeze and will move out of the opening as it expands—leaving the bottle intact. Thermal cycling from -10°C-25°C, both with the sample totally submerged and with only a small amount of water present in the composite, indicates no significant loss in compressive strength after 75 cycles. Another potential benefit of the Filterpave system in a cold weather climate is that it should not require salt for ice removal. In general, ice on pavement develops from snow melting and then refreezing. In the case of Filterpave and other porous pavement, if the porosity is maintained, the water from snow melt moves through the composite and does not refreeze on the surface. Snow removal from a Filterpave surface is the same as that for conventional pavement, except that a flexible blade tip should be used for plows or snow blowers to prevent gouging of the surface. Power brushes may be used without modification. When properly installed, Filterpave pavement will remain remarkably stable. The thermoset polyurethane binder provides stability over a wide temperature range that will not

soften significantly at high temperatures to allow rutting. A properly installed base for the pavement should be very stable, but if there is settling or partial washout of the base, Filterpave pavement can bridge substantial gaps. If it does begin to fail, the failure may not be catastrophic, because the material maintains a resistance to stress even after the peak stress level is reached (see Figure 4). Eventually, the material fails catastrophically, but not until a substantial deformation of the sample occurs. Another reason the pavement remains stable is that plant roots will have less of a tendency to crack or break up the pavement, because the porous composite allows water and nutrients through to any roots that infiltrate the base. Filterpave pavement can also help reduce the urban heat island effect. All five color variants of the pavement have an SRI substantially greater than 29, which is the minimum requirement to achieve a Leadership in Energy and Environmental Design (LEED) credit for the reduction of heat island effect for non-roof structures. In addition, the porosity of the pavement allows it to cool more quickly than many alternatives because of heat loss due to convection and possibly evaporative cooling from any water within the structure. Filterpave pavement is easy to install using conventional concrete equipment. It is formed and finished similar to low-slump concrete. The material can be mixed in a batch process on a small scale using a concrete or mortar mixer. The PUR is mixed and added to the aggregate in the mixer, blended for a few minutes, and then placed into the forms. The mixed PUR and glass aggregate has a working time of 30-45 minutes. A vibratory screed is often used to provide a slight compaction/settling of the material in the forms. A smooth finish is achieved by working the surface with a bull float (Fresno blade) or a power trowel, and the edges around the forms are finished with a ¼-in. radius edge trowel. Depending on weather conditions, the material is tack-free within four to six hours, can be walked on in 24 hours and has achieved 95% of its final hardness within 72 hours. If the surface is to be driven on, it can typically withstand the force of vehicle traffic after four days. February 2011

Finally, the wearing course of Filterpave is installed: 3½ in. thick (2 x 4 in. forms) for driving surfaces and 2½ in. for other areas. In the last two years, the pavement has been used in a variety of applications. Over 40 different installations have been completed, including residential driveways, walkways, patios, commercial parking areas, and golf cart paths. Figure 7 provides some examples of these installations.

CONCLUSION

Figure 7. Examples of Filterpave Porous Pavement Installations

The next time you walk across a dirtylooking parking lot, imagine how much mores aesthetically and environmentally pleasing it would be if it were made with a porous pavement. Filterpave can help manage stormwater by reducing or eliminating runoff, and it allows rain water to flow through the structure and naturally filters out many pollutants before the water replenishes the local aquifer. Filterpave pavement is stable to freeze-thaw cycles, reduces urban heat island effect and is easy to install. It can be used for light- and medium-duty traffic areas such as driveways, parking areas, cart paths, walkways, and patios. Using post-consumer recycled glass aggregate and a pigmented thermoset polyurethane, the pavement provides an aesthetic quality that cannot be achieved with other pavements, and it contributes to LEED credits or NAHB Green Points.

nce upon a time, the act of saving the environment seemed to be limited to a yearly celebration called Earth Day during which, as on New Year’s, people made resolutions that they wouldn’t necessarily keep. Saving the environment and contributing to a healthier world has seemed like a great idea for decades, but everyone has always had an excuse; it is either too big a task for one individual, or it is a terribly time-consuming activity that could cut into potential money-making time. Then things started to change at work, school and home. From unthinkable gas prices and a tough job market to skyrocketing health care costs, many folks have come to a similar conclusion: it is time to become more resourceful and live better. For example, there has been a rise in eating locally. Not only does locally grown food taste better than grocery store products, but buying locally and eating what is in season saves money and conserves the necessary resources that are used to transport food to one-stop shopping nationwide. Businesses are looking more closely at their waste, too. Is it really necessary to throw dollars away on everything from the energy needed to power an office 24/7 to disposable coffee cups and plastic packaging for products? Many methods are available to jumpstart your green initiative and operate your business in an eco-friendly and sustainable way. The best way to discover these methods is to observe how other businesses are doing it.

HOW TO SUCCEED AT GREEN To get your juices flowing, here are six businesses that are successfully initiating the green movement. These multinational businesses received Natural Health Magazine’s Green Choice Awards in 2009 for their excellence in leading by example across the globe. Wal-Mart. Although many have been skeptical of this retailer’s green practices in the past, Wal-Mart now has a very large-scale environmental plan of action to power each of its stores with 100% renewable energy. Wal-Mart plans to set aside $500 million a year to increase fuel efficiency within its truck fleet, decrease solid wastes and energy consumption in its stores, and implement a number of other environmental endeavors. Starbucks. With a “bean-to-cup” motto and approach to business, Starbucks uses environmentally savvy methods at each stage of production. Made from post-consumer goods, Starbucks’ recycled cup sleeves saved more than 78,000 trees in 2006. Verizon. Its HopeLine initiative saved more than 5.6 million cell phones from ending up in landfills; instead, they were used to fund more than $6.3 million in cash grants to domestic violence agencies. Verizon has played a leadership role in encouraging customers and shareholders to choose paperless options. In addition, Verizon Wireless has signed agreements to deploy smart power grids and has continued Adhesives & Sealants Industry

to upgrade its fiber-optic network with equipment that performs four times more efficiently while reducing cooling costs. This is equivalent to keeping as many as 16,000 cars off the road annually. Whole Foods. This organic and natural food chain was the first company to buy enough wind energy credits to compensate for 100% of the electricity it consumes. Whole Foods has eliminated its use of disposable plastic bags and replaced them with reusable bags (made from recycled plastic bottles) for customers. Av e d a . This natural beauty product manuf a c t u r e r u s e s p r i m a rily organic materials in its products. Aveda also employs wind power in its manufacturing facility to reduce electricity consumption, and it uses 100% recycled packing materials. In addition, Aveda funds wildlife preservations. Since 1999, the company has raised $8 million for environmental causes. Discovery Channel. This company is not only eco-conscious in the information that is communicated via its many environmentally focused television shows, but also through its corporate actions and practices. The Discovery Channel has compensated for CO 2 emissions by making equal contributions to environmental projects and using energy-efficient lighting, architecture, and water systems in its company headquarters. In August 2010, Discovery Channel took over a leading environmental lifestyle website, treehugger.com, as part of the company’s initiatives to inform people about important environmental issues. The company has also set aside $50 million to create green television programming and introduced a new show, “Ways to Save the Planet.”

RENEWABLE ENERGY SNAPSHOT

The global wind and solar energy markets are both expected to expand. ccording to BCC Research, the value of the global market for renewable energy was nearly $225 billion in 2010 and is expected to increase at a compound annual growth rate (CAGR) of 8.1% to $331 billion by 2015. The largest segment of the market, wind energy, is projected to increase at a CAGR of 6% to $87 billion in 2015, after being valued at an estimated $65 billion in 2010. The solar energy segment is expected to see the highest rate of growth over the next five years, with a CAGR of 17.1%, rising from an estimated $44 billion in value in 2010 to $97 billion by 2015.

A

WIND ENERGY Wind could meet 12% of global power demand by 2020 and up to 22% by 2030, according to the Global Wind Energy Council (GWEC) and Greenpeace International. The Global Wind Energy Outlook 2010 finds that wind power could play a key role in satisfying the world’s increasing power demand while simultaneously achieving major greenhouse gas emissions reductions. The 1,000 GW of wind power capacity projected to be installed by 2020 would save as much as 1.5 billion tons of CO2 every year. These reductions would represent 50-75% of the cumulative emissions reductions that industrialized countries committed to in their 2020 Copenhagen pledges. By 2030, a total of 34 billion tons of CO2 would be saved by 2,300 GW of wind power capacity. “Wind power can make a massive contribution to global electricity production and to decarbonizing the power sector, February 2011

but we need political commitment to make this happen,” said Steve Sawyer, secretary general of the GWEC. “Wind power technology provides governments with a viable option for truly tackling the challenges of our time and for being part of the energy revolution our planet needs.” In addition to environmental benefits, wind energy is becoming a substantial factor in economic development, providing more than 600,000 “green collar” jobs today both in direct and indirect employment. By 2030, the number of jobs is projected to increase to over 3 million. “In 2010, the 600,000 workers of the wind industry put up a new wind turbine every 30 minutes—one in three of those turbines was erected in China,” said Sven Teske, senior energy expert with Greenpeace International. “By 2030, the market could be three times bigger than today, leading to a @202 billion (~ $280.9 billion) investment. A new turbine every seven minutes—that’s our goal.” According to a report from Research and Markets, high initial costs and the huge structure of large wind turbines have given rise to the less costly small wind turbine market. Small wind turbines, which have a power rating of 100 KW or less, are lightweight, allowing them to function with light wind. In addition, they can be mounted on rooftops like television antennae and they produce little noise. The most commonly used technology for these turbines is the horizontal axis wind turbine, but other technologies like loopwing turbines are also available. Adhesives & Sealants Industry

RENEWABLE ENERGY SNAPSHOT In previous years, small wind turbines were used to generate power to charge batteries; now, technical developments have allowed these turbines to be used to power homes and businesses. Government support and awareness for renewable energy will likely help the market for small wind turbines to grow rapidly. Technological advances have allowed wind turbine blades to become lighter and smaller, yet more efficient. Similarly, the rotor speeds have been slowed down to decrease noise, and vibration isolators have been introduced. Self-protecting technologies that help the wind turbine to protect itself in case of high wind speeds, along with active pitch controls to capture energy at these high speeds, have been introduced. In addition, some small wind turbines feature wireless connectivity, allowing owners to control the turbine dynamics from a distant location.

SOLAR ENERGY The solar energy industry experienced the proverbial “perfect storm” of marketchanging events in 2009 that redefined the rules of the game, according to Pike Research, thereby altering the competitive landscape as well. Starting in late 2008, the solar market shifted from supplyconstricted to demand-driven within a few quarters, due to the plunging price of crystalline silicon cells and modules spurred by falling polysilicon cost, constrained availability of credit, Spain’s dramatic demand decline, and the growth of thin film supply and market share. “The solar market is now faced with a gross oversupply of modules,” said Dave Cavanaugh, senior analyst. “The industry is currently supplied by more than 190 cell and module manufacturers, making consolidation of weaker competitors an inevitable outcome.” A few of Pike Research’s other key forecasts and findings about the new solar market include: • Worldwide solar demand, driven by lower costs and greater availability of credit, was anticipated to increase to 10.1 gigawatts (GW) in 2010, a yearover-year increase of almost 43%. • Solar market demand will exceed 19 GW by 2013, a 25% CAGR from 2010; this growth will be driven by demand from the U.S., Italy, and China, in addition to steady demand from Germany and demand growth in a number of smaller countries. 38

• Excess module supply could easily reach 8.3 GW in 2010, even accounting for reasonable usage rates and moderate capacity growth. As a global superpower, the U.S. represents a fast-growing and potentially strong photovoltaic (PV) industry, according to a report from Research and Markets. Increasing budget expenditures on crude oil, gas and coal; high grid installation and expansion costs; and increasing carbon emissions have triggered PV industry growth in the U.S. over the past few years. The total PV and concentrating solar power (CSP) capacities surpassed 2 GW in 2009, with a significant increase in industry revenue. According to the report, the U.S. government continued its support and substantially increased the solar energy technology budget. Out of the total $271 million in solar energy investments, 182 solar projects had received

Treasury grants of $81 million (as of early February 2010). With the help of notable government efforts and active participation of venture capitalists, the industry was expected to add around 0.87 GW of annual PV installations in 2010. The non-residential segment has shown the highest growth potential. In 2010, the impact of federal stimulus funds reached full effect, and installations suddenly rebounded with easy credit facilities and various state government tax-incentive programs. Another trend seen in the non-residential segment was the usage of power purchase agreements (PPAs). Various companies have now begun signing PPAs to make these installations more profitable and viable for the long term.

WHAT’S NEW RAW MATERIALS CVC THERMOSET SPECIALTIES GLYCIDYL ESTERS

This company, an Emerald Performance Materials company, has introduced a new glycidyl ester product line. The patent-pending technology addresses a need in the marketplace for impact modifiers that deliver both high peel strength and high impact strength while maintaining a high Tg in the epoxy matrix. The new products can provide effective alternatives to traditional core-shell and high-molecular-weight non-epoxy type polyols used as impact modifiers, which may offer either high impact or high peel adhesion but typically are not delivered optimally. New products include Hypro 1300X63 ETBN, Hypro 1300X68 ETBN, and Hypro 2000X174 ETB. The first two are diglycidyl esters of low-molecular-weight butadieneacrylonitrile copolymer; the third is a diglycidyl ester of a low-molecular-weight butadiene homopolymer.

ASK

AD INDEX

DR.DAVE

QUESTION: I am researching gluing products and production methods for a customer. I will be bonding polypropylene, polycarbonate, polyethylene or polymethylmethacrylate plastics to a coated aluminum foil. The plastic pieces will cover small compartments containing the customer’s product, and I need to be able to peel away the plastic piece, taking the entire foil piece to which it has been glued without any possibility of failure. I need to obtain around 20 N/cm². I cannot have temperatures over 50°C during the gluing procedure, and I need the adhesive to have FDA approval. What do you recommend? ANSWER: I might have recommended a high-performance hot melt for your application, but since you don’t want to exceed 50°C as your application temperature, I think you should look at a cyanoacrylate adhesive. Several FDA-approved cyanoacrylates are available. However, if you choose to use the polypropylene or polyethylene as your substrate, you will need to treat the surface (e.g., plasma treatment or a special polyolefin primer with the adhesive). QUESTION: We want to adhere PVC to PVC and EVA to PVC without using a cyanoacrylate adhesive. What is the solution?

Several FDA-

ASK

ANSWER: PVC can often be approved a difficult substrate to bond, particularly if it is flexible. Adhesives that give a good cyanoacrylates are initial bond often degrade over time because of plasticizer available. migration from the PVC. Assuming that you don’t want to handle a solvent-containing adhesive, I would recommend that you look at a tough acrylic adhesive for the application. These adhesives are available as either two-component mixable systems or as a system comprising a low-viscosity primer applied to one surface and the adhesive to the other surface.
