A Simple Suggestion to Help You Squeeze More Profit Out of Every Cartridge

Get Rid of the Cartridge Poly-clip introduces a low-cost alternative to expensive cans and pre-formed single-use cartridges. The Poly-clip foil-pack tube for lubricants, adhesives and sealants. And, because one roll of film makes thousands of tubes it offers a consistently better seal with lower equipment, materials and maintenance costs than vertical tube forming systems and heat seal closures.

Environmentally conscious consumers will appreciate the fact that an empty tube is less than 8% the size of an empty cartridge

Hosted by ASI, Assembly, CircuiTree, Quality and World Trade magazines, the virtual event featured 29 exhibitor booths, as well as multiple webinars, Ask the Experts sessions, podcasts, networking opportunities and more. Attendees were very receptive and enthusiastic, with over 95% of survey respondents indicating that they would recommend the event to others. One attendee in particular provided feedback that I’d like to share with you: “Thanks to you and your colleagues for the fantastic experience at the Tech ManufactureXPO. Over 25 years I have attended or exhibited at many trade shows in many sectors around the world. I never thought that there could be a virtual equivalent to a physical show. I spent a little over an hour on your show and made a good number of contacts and had some very interesting discussions. I also learned a lot in a very short amount of time. The content, quality of exhibitors and the mechanics of navigating the show were excellent. It was well worth my time.” If you’d like to exhibit or otherwise participate in next year’s Tech ManufactureXPO, please contact our publisher, Amy Vallance, at [email protected] or (281) 550-5855.

FOCUS ON

FISNAR CELEBRATES 25 YEARS By James Dornan, Marketing Manager, Fisnar®

hen Fisnar began operating in 1986, it was with a long-term view that the use of fluids in industry would steadily increase well into the next millennium. This recognition has proven insightful, as fluids for many different processes are now used in every industry—and all require dispensing solutions.

W

DISPENSING SOLUTIONS Fastest growing among industrial dispensing opportunities are medical, automotive, electronics and renewable energy sectors; automatic dispensing and assembly have replaced traditional manual methods in these markets. Robotic automation features high on the list of dispensing solutions offered by Fisnar. A large selection of bench, gantry and SCARA robots is available, each equipped with simple-to-program dispensing language software and instructions. The most effective method of proving a dispensing solution is to offer a free trial to the prospective customer. A finished narrated video, showing the programming of the recommended equipment and material feed, is returned with the finished product sample. Recognizing the importance of being a global company, Fisnar established offices throughout the world, servicing a network of global distribution companies. The company is now an international brand leader with several manufacturing facilities.

In-depth knowledge is required to control and apply the dispensed liquid in medical applications.

By Cliff R. Bockard, CEO, mta automation inc.

www.adhesivesmag.com

ver the last few years, the medical industry has advanced to fully automate a variety of applications, including the dispensing process. Dispensing liquid or viscous fluids, such as epoxies, silicones, polyurethanes, greases, oils, lacquers, or one- or two-component materials, has become increasingly significant in the medical industry. As the trend toward smaller end products continues, the dispensed volume decreases and applications become progressively more complex. This means in-depth knowledge is required to control and apply the dispensed liquid. In many cases, customized solutions are necessary. In situations where two-component products are dispensed manually, the preparation of the homogenous mix in the proper ratio requires a skilled operator. Due to the manual nature of the process, the risk of improper handling enters into the equation while the operator is exposed to the materials during preparation and application. Such personal contact with resins can create drastic difficulties. Economically speaking, the process of manually weighing, mixing, and pouring polymers into syringes is also wasteful and time consuming. The product is mixed in large quantities, yet only a small amount of the mixture is useful since its physical properties change. In addition, the product reaches its pot life (double viscosity) much sooner than if it were mixed in a smaller quantity.

O

June 2011

THE END OF MANUAL DISPENSING Full automation of the mixing and dispensing processes esses eliminates operator exposure and the need to manually handlee the resin and hardener. These types of applications illustrate the need for highly precise, easy-to-use mixing and metering dispensing systems. When dispensing volumetrically via positive displacement, a specific amount of product can be mixed and dispensed within the same machine, which ensures repeatability and consistent physical properties. In this instance, two cartridges are filled with the associated product to be dispensed, and the prepackaged cartridges are placed on two numerical-volumetric dispensing heads. The resin and hardener are dispensed into a mixing chamber by programmable mixing ratio and thoroughly mixed just before they are applied to the product. This device allows dynamic mixing of small volumes for two-component products. The quality of the mix can be achieved by altering the mixing time or speed, or the size of the mixing chamber. For some products, it is important to mix with a low speed to prevent cavitations and degassing. The ratio of the product can be freely programmed and does not depend on the sizes of the dispensing units. Automation provides two main advantages: the mixed product is very small (maximum of 2,300 mm 3), and the materials are mixed just before dispensing. In addition, the repeatability of the dispensed volume is always constant and does not depend on the viscosity of the material. Other advantages include volumetric piston pump dispensing, piston and liner in Al2O3, no moving seals, a liner driven by a stepper drive, and all wetted parts reduced to PTFE/PVDF/PP/V2A and Al2O3 materials. Because the chamber is of such low volume (as low as 60 mm 3 ), only the volume that is going to be dispensed is actually mixed. Therefore, the mixing chamber is completely flushed, and the product within the chamber is constantly renewed. Since it is designed as a consumable, it is not necessary to use any hazardous or expensive cleaning agents after use. In addition, the mixing chamber is chemically inert with a design based on PTFE/PVDF, PP and stainless steel. eel. The operator does not come into contact act with the adhesive or have any direct physical access to the metering and mixing process, thus eliminating all possible errors ors that could result from improper handling. g.

FIELD APPLICATIONS Many examples of required precision in dispensing can be found in the field. One such application includes dispensing fluid product to produce contact lenses. The objective is to have a very high accuracy of the dispensed product with low deviation—less than 1%—from nominal volume. Nominal volumes are generally less than 40 mm 3 andd operate in clean room class 10,000. Another medical application is the filling of a medical pump with h a twoJune 2011

The filling of this medical pump with a two-component epoxy requires precision and accuracy.

component epoxy (Delo Duopox 1895), which requires great precision and accuracy. Here, a two-component dispenser is needed to dispense the product into a small hole to fill up a cavity while avoiding any air bubbles; the mixture and ratio of the two-component product needs to be perfect. In addition, the tolerances of quantity to dispense are very small. The previously described dispensing process resolved these issues with ease. In the vascular field, pacemakers often require RTV-silicone mono-component to be dispensed. The complex nature of pacemakers often benefits from peripheral automation, including conveyorization and clean room compatibility. The recentering of the part and tip can be also performed with visual aids. All of these actions are crucial to the accurate execution of the dispensing processes with 3-D interpolation and predefined trace pattern.

AUTOMATION SOLUTIONS In general, automation of the dispensing process can be achieved in one of three ways: semi-automatic in-line, semiautomatic manual and fully automatic. For dispensing operations that cannot be integrated into fully automatic production lines, tabletop solutions offer maximum flexibility. When volumes increase and throughput demand iis high, a robotic cell with automated handlers—ranging from automa z-movement to full-scale robotics z-mov with rotary tables, conveyors and choice of dispensing heads—is ch ccustomizable for virtually any pproduction line job. In any case, the automation of dispensing within the medical device arena is moving forward at a rapid pace and continues to show drastic repeatability and throughput superiority over manual operations. m For more m information, contact mta automation inc. at 50-1 River St., Old Saybrook, CT 06475; call email [email protected]; or (860) 399-1141; 399 visit www.m www.mtaautomation.com.

An endless piston dispenser meets the needs of almost any precision dosing application.

By Gerald Pfeiler, CEO, ViscoTec-America Inc.

ixing and dosing stations based on the “endless piston principle” allow reliable precision dosing of two-component materials. Compared to conventionally applied systems, this new application technology can offer excellent dosing repeatability of medium- to high-viscosity adhesives and sealants. Modern production processes increasingly involve two-component materials. The automobile industry tops the list, followed by the manufacture of electronics, solar technology, aircraft, trucks, sports goods, commodities and even clothing. All of these industries rely on adhesives, sealants, fillers and other insulating materials that are made from two-component materials. The most significant feature of twocomponent processing is that mixing both components in their correct proportions enables the adhesives to cure to reach their ultimate strength at

the production stage, and not before. This offers considerable advantages for the storage of raw materials, as well as the application process itself.

RHEOLOGY DEMANDS FLEXIBILITY The wide range of industries requiring two-component materials naturally gives rise to a variety of requirements and properties, such as dielectric strength in electronics, density, and ultimate strength of adhesives or shrinkage during the filling and casting processes. As a result, a huge variety of materials— all with different viscosities, fillers, mixing ratios and thixotropic properties—is now commercially available; the majority of these are silicone, epoxy resin or polyurethane-based products. The abundance of available materials is good news for processors of adhesives, as it is easy for them to obtain the exact products they require for a particular application. System manufacturers,

on the other hand, consistently have to deal with the constantly changing rheological properties of the materials used. Parameters such as filler content, viscosity, or flow limits play a critical role, particularly in the automated mixing of two-component materials. The ever-shorter opening times are favorable for growing cycle time requirements, but they are challenging for the system manufacturer. In addition to dosing accuracy, the main objective for the optimized automation of such applications is the realization of constant, exact mixing ratios. It is here that rheology exerts its influence. Figure 1 (p. 21) shows a typical system layout for a two-component application for larger quantities; it consists of a material supply, two pumps, a certain length of hose relevant to the size of the system, two flow meters, two valves, one mixing head, and the (usually) static mixer.

As previously mentioned, the flow properties of the products, as well as the individual components of resin and hardener, vary significantly. Thus, if the dosing pumps start simultaneously, different rates of pressure expansion will be produced in the lines, resulting in fluctuations in the mixing ratio at the beginning and the end of the dosing process. To offset this, complex electronic control systems that involve pressure buffers, valves and various hose diameters are used. When changes i n r h e o l o g i c a l p r o p e r t i e s o c c u r, adjustments often have to be carried out. Temperature fluctuations occurring in the course of a day and a year will usually lead to an unstable result.

THE ENDLESS PISTON PRINCIPLE A two-component dispenser based on the endless piston principle was developed to provide a solution to these challenges (see Figure 2). The volumetric dosing pumps work independently of viscosity or counterpressure and are placed directly in front of the mixing tube. Due to their lack of dead space and short conveying distances, the flow properties of the dosing media have no impact and mixture fluctuations are alleviated. As can be seen in Figure 3, the dosing pumps are connected to the mixer inlet via single, optimally streamlined channels, so the products to be mixed are kept separate until they reach t h e s t a t i c m i x e r. A n a l o g p r e s s u r e sensors, which are flush-mounted to eliminate contamination, monitor the dosing result and protect the pump from overpressure caused by product hardening in the mixers. At the end of dosing, the pressure reduction can be adjusted individually for each component by a defined reverse-flow, which prevents dripping from the mixer. The components are available immediately in the correct ratio for a new dosing sequence to start. The feed of product to the mixing head is a considerably less sensitive operation, with pressures ranging from 0 to 20 bar, provided that the dosing pumps are properly filled. The system can process viscosities ranging from 0 to 2 million mPa, while mixing ratios are between 1:1 and 100:10, provided static mixing is present.

can operate in highly complex industrial applications or as a low-cost tabletop unit, depending on the requirement. The unit is designed for bead and dot applications, as well as volumetric filling, and provides continuous monitoring of all process parameters (e.g., pressure, product supply, open time, etc.). The unit can be easily installed in existing systems, and the supply tanks do not have to be replaced in most cases. The lightweight (8-9 kg, depending on the drive technology) two-component dispenser can be integrated into almost any robot or XYZ system. Since the dosing pumps are completely linear, they can be combined with practically any type of variable drive, and system manufacturers are able to continue using their own drive technology. The analog evaluation of the pressure sensors allows the pressure curve for every dosing

sequence to be transferred to a process control system for recording, thus ensuring 100% control.

A PRACTICAL EXAMPLE With the aim of increasing production efficiency and improving quality, a wellknown kitchen appliance manufacturer sought new solutions for the application of two-component adhesives. The task involved sticking aluminum strips onto glass sheets; the existing dosing system could only produce long adhesive beads. Small dot dosing resulted in too much adhesive being dispensed, and large quantities of product accumulated at the start and stop of application. In collaboration with a system integrator for high precision and flexible automation solutions in assembly robotics, test engineering, and plant design, a complex dosing cell using June 2011

Figure 1. Schematic of a Standard Two-Component System with Gear Pump

Figure 2. Endless Piston Principle

Figure 3. Two-Component Dispenser Design Based on the Endless Piston Principle

the new dosing head was designed for the application of twocomponent adhesives. One advantage of the dosing cell is that the programming of dosing parameters, as well as axis systems, can be varied in defined limits in a graphical interface. A recipe memory stores all possible variations of the assembly parts, and the production program allows the selectable application of small dots and long beads for each part. Since no separate dosing controls are required, the communication and June 2011

coordination problems that often occur in conventional dosing systems are avoided. The user of this system* is now in a position to manufacture all variations of assembly parts using only one dosing cell. The company can easily change from one adhesive application to the other (i.e., from the smallest dots to lengthy beads) while being sure of a precise and uniform result every time. Because it is already well-established in the market and in two-component technology, the endless piston dispenser was the obvious choice of dosing technology for this application. All of the desired features, including simple operation, absolute reliability, easy integration and maintenance, broad application capability, and lightweight construction, were combined to develop the two-component dispenser.

Cool roof coatings provide a method to reduce global carbon emissions and slow climate change. By George Daisey, Lead Applications Development Scientist, Dow Construction Chemicals, The Dow Chemical Co.

ool roof coatings are gaining attention as a costeffective and easy way to improve the energy efficiency of buildings. Introduced in the U.S. in the 1980s with the aim of reducing solar energy absorbed by buildings and the buildup of heat gain in urban environments, cool roof coatings have gained even more traction in recent history. U.S. Department of Energy (DOE) Secretary Steven Chu, Ph.D., has embraced cool roof options as a method to reduce global carbon emissions and slow climate change, and has directed the installation of cool roofs on all DOE facilities. The DOE estimates that cool roofs can reduce energy usage by up to 50% during peak loads and that every 1,000 ft2 of conventional roofing materials replaced with reflective elastomeric roof coatings will offset 10 tons of CO2 emissions annually.

C

MULTIPLE BENEFITS One effective method of quickly installing a cool roof is to apply an acrylic elastomeric roof coating over the existing, serviceable substrate. This type of coating can be designed to adhere to a variety of roofing surfaces, providing a way to con28

vert a hot roof into a cool one. Usually white or off-white in color, acrylic elastomeric roof coatings reflect nearly 90% of solar radiation from the roof, preventing that heat from being absorbed into the building. In addition, their high heat emissivity means they readily release any energy absorbed. Acrylic elastomeric roof coatings are most suitable for the horizontal or flat roofs found on many commercial buildings or row homes. Figure 1 shows the surface temperature over time of a black roofing shingle vs. the same type of shingle coated with a white acrylic elastomeric roof coating. The maximum air temperature reached on the day of the data collection was 90°F. The black asphalt shingle reached a maximum temperature of 160°F at that time, while the same black asphalt shingle coated with a 100% acrylic elastomeric coating stayed below 100°F. The cooler temperatures on the surface of the roof mean lower temperatures inside the building, which reduces the associated load on air conditioning systems as well. Figure 2 contains data from a room on the top floor of a row home in Philadelphia, PA. The graphs show the difference between the ceiling temperature and the air temperature in that room over June 2011

CHEMISTRY INNOVATIONS The benefits of acrylic elastomeric roof coatings are many; acrylic chemistry serves as the key ingredient, enabling the flexibility, adhesion and durability required to drive the performance of the coatings. Flexible Combination A roof is constantly expanding and contracting with temperature and humidity fluctuations, the weight of snow and rain loads, wind uplift, and even vibrations of the building. An acrylic elastomeric roof coating must be flexible to accommodate this movement while also tolerating impact from foot traffic, tools and equipment on the roof. The technology to develop a flexible, yet tough, coating is a challenge. In an acrylic elastomeric roof coating, simply using a soft acrylic monomer to provide flexibility will not work—it will make the coating too tacky, leading to greater dirt pickup and reduced reflectivity. Using a hard monomer and plasticizing it will not work for the same reason. Therefore, the technology design for acrylic elastomeric roof coatings needs to be a unique combination of soft and hard monomers co-reacted with multiple proprietary chemistries that meet the specific needs of the coating. Many monomer options are available, but consider a basic example of a soft monomer (butyl acrylate) and a hard monomer (methylmethacrylate) combination:

four daytime periods. As shown on the left, before the application of an elastomeric roof coating, the peak temperature of the ceiling is typically about 5°F hotter than the room temperature and as high as 9°F hotter. After the coating application, the temperature difference is generally about 1°F and sometimes 0°F, which demonstrates the effectiveness of the coating at reducing heat gain from the roof to the room. It should be noted that some of the temperature variation could also be a result of changes in the air conditioning setting in the room, which would cause room temperatures to drop more quickly than ceiling temperatures and is often small enough to be within the potential measurement error of the sensors. Applied six to eight times thicker than regular house paint, acrylic elastomeric roof coatings are designed to be durable, yet flexible. Due to their ability to resist water, moisture, frost, salt, ultraviolet (UV) radiation and other outdoor elements, these coatings provide solutions for extending the service life of roofs as well. When an acrylic elastomeric roof coating is applied over a serviceable roof before it fails, the coating can extend the life of that roof for many years. In addition, installing a roof coating can be a cost-effective alternative to roof replacement when the roof is significantly weathered. Using a coating rather than replacing the roof also helps minimize the waste that results from a roof tear-off.

Figure 3. Acrylic Elastomeric Roof Coating vs. Conventional Roof Coating

Butyl Acrylate

Methylmethacrylate

Butyl acrylate (BA) has a glass-transition temperature (T g) of -54°C, while methylmethacrylate (MMA) has a T g of +105°C. Because of its low T g, a homopolymer of poly-BA is extremely soft and can make a fine adhesive. The higher T g June 2011

of a homopolymer of poly-MMA means it can be made into hard-coat clear coatings. These monomers can be reacted by emulsion polymerization to create thousands of products. In the case of acrylic elastomeric roof coatings, joining these two in the right combination can achieve a unique balance of properties, such as greater flexibility with good film toughness. Proprietary chemistries are then added to modify features like chain length, linearity, sidechain functionality, and custom end-use characteristics like surface crosslinking or affinity toward a substrate. In turn, these features can improve properties like dirt pickup resistance, solar reflectivity, water resistance and adhesion to a variety of substrates. Adhesives & Sealants Industry

Specialized Adhesion Acrylic elastomeric roof coatings can be custom designed to adhere to—and perform well on—a variety of roofing surfaces. Existing horizontal roof substrates include ethylene propylene diene monomer (EPDM) rubber, built-up asphalt, thermoplastic polyolefin (TPO), polyvinyl chloride (PVC), Hypalon, modified bitumen, concrete, metal, smooth or granulated capsheet, and even fresh asphalt emulsion. An acrylic elastomeric roof coating product is specifically designed for each of these surfaces to ensure performance and adhesion. For example, the majority of modified bitumen products on the market are modified with atactic polypropylene (APP). Adhesion to APP-modified bitumen is extremely difficult, but a combination of the right reactants and acrylic polymers can yield an elastomeric roof coating formulation with outstanding adhesion performance on the substrate. Both coatings shown in Figure 3 (p. 29) have been exposed to six weeks of water immersion. The coating on the left is an acrylic elastomeric roof coating designed specifically for adhesion to APP-modified bitumen. It has retained significant adhesion despite the long period of water immersion. The conventional roof coating on the right has blistered and peeled excessively due to ponding water during the exposure. A more recent development is an acrylic elastomeric roof coating with excellent adhesion to weathered TPO membranes. Like APPmodified bitumen, TPO roofing membranes cause adhesion challenges. The secret to TPO adhesion is reducing the contact angle, or the angle made between the TPO surface and the leading edge of the coating. Figure 4 illustrates why a smaller contact angle is important. A hydrophilic surface better absorbs moisture and produces a smaller contact angle. The smaller the contact angle, the better the adhesion

June 2011

and wettability. Excellent wettability occurs when the coating “wets out” or perfectly covers the surface. When wettability is poor, the coating pulls or even runs, leaving areas of the TPO uncoated. Measuring the contact angles of various TPO substrates over time revealed that the angle actually increases as the membrane weathers, unlike most surfaces that decrease in contact angle with weathering. After determining the conditions and materials that were causing the TPO’s increase in contact angle, the angle was manipulated to match that of the roof coating formulation, which ultimately resulted in an acrylic technology with excellent adhesion to weathered TPO. Durability and the Effect of the Sun A key property required of any roof coating is durability, which implies resistance to the effects of weather and UV radiation degradation from the sun. UV radiation causes a noticeable change in the appearance and durability of many roofing substrates. For example, as the asphalt in asphalt roofing membranes is exposed to solar radiation, the asphalt begins to break down because it is not resistant to UV light. Granules are used in shingles, capsheets, and even on roadways to help protect the asphalt, but UV light still gets through and degrades it. After about six months of UV exposure, a brown chalky residue begins to appear on the surface of an asphalt-based coating and it begins to crack and erode—a clear indication of UV degradation from the sun. The white pigments in an acrylic elastomeric roof coating are what provide the solar reflectivity. Since the acrylic polymer in the coating is transparent to UV light, solar radiation causes very little degradation of the coating. Thus, white elastomeric roof coatings can provide both high solar reflectivity and outstanding durability.

Efficient reflectivity also prolongs the durability of the roof coating and, ultimately, the roof itself. Acrylic elastomeric roof coatings achieve effective long-term reflectivity due to the ability of the acrylic polymer to resist dirt pick-up and keep the coating white. Figure 5 shows reflectance data from acrylic elastomeric roof coating exposure testing at a chemical production facility in Philadelphia. This data was collected for eight years—far longer than the three-year durability requirement of ENERGY STAR program ratings. ENERGY STAR requires a coating to be weathered outside for three years and maintain a minimum solar reflectivity of 50, as a value of 50 qualifies a coating as reflective. Even after eight years, these two acrylic elastomeric roof coatings have reflectivity values above the ENERGY STAR three-year requirement.

TECHNOLOGY FOR A COOL FUTURE In addition to the benefits they provide, acrylic elastomeric roof coatings are easy to apply and maintain—periodic cleaning and application of a maintenance coat can continually help extend the life of many roofing substrates and improve the energy efficiency of buildings. Durability, adhesion, reflectivity and flexibility remain some of most important characteristics for acrylic elastomeric roof coatings, and advancements in each of these areas will be essential going forward. Clearly, as cool roofing solutions continue to generate interest and excitement, the need for innovation in the chemistries that drive those coatings will accelerate as well. A continued emphasis on innovation is the only way to fully capture this burgeoning trend and opportunity. Visit www.dowconstructionchemicals.com for more information.

Manufacturers are now taking video collaboration outside of the boardroom and onto the plant floor. ideo conferencing has become a standard form of communication across enterprises. In fact, video conferencing is expected to become a $10.8 billion industry by 2015. The standard form of video collaboration facilitates face-to-face meetings in video conferencing meeting boardrooms. For manufacturers, though, the heart of their business is often the plant floor-where traditional video conferencing doesn’t reach.

V

SECURE MOBILE VIDEO With the development of new mobile technologies, the opportunity for video collaboration has expanded. Manufacturers are now taking video collaboration outside of the boardroom and onto the plant floor, to a supplier location, or into the field where the problems are occurring. These mobile technologies generally include wireless video devices for use on the plant floor and collaboration software for the remote experts’ desktops. Plant workers use the mobile device to share video, voice, telestration (i.e., onscreen drawing) and images with the experts who interact live through the collaboration PC software. Remote experts can also share images or pre-recorded videos to play on the touchscreen panel of the device. By sharing this visual content, the experts can provide plant floor personnel or field technicians with visual instructions. 32

For many manufacturers, their plant floor operation contains competitive and sensitive information; for this reason, cameras are typically not allowed on the plant floor. In many Fortune 1,000 companies, potentially “rogue” video devices such as smart phones must be checked at security. New video conferencing mobile devices overcome that concern by providing tight security over the wireless communication, media content and device usage. Security, encryption, authentication and even centralized administrator control have become tablestakes for mobile video collaboration products.

REDUCED DOWNTIME For one major consumer packaged goods (CPG) manufacturer, this kind of mobile collaboration has helped in various operational situations, including production line equipment maintenance and repair, supply chain interaction, and OEM vendor communication. Video collaboration was first used on the CPG manufacturer’s plant floor to help maintain and repair critical production line equipment. If a machine was down and the right engineer was not available onsite to troubleshoot the problem, downtime rapidly escalated. By using the mobile video device to show a remote expert the failed equipment, the manufacturer was able to remove costly delays from the repair process. Together, the production June 2011

line engineer and remote specialist can now collaborate to identify immediate corrective action plans. Production equipment downtime costs can be staggering. With downtime costs averaging from $500 for a standalone machine, $1,500-8,500/hour for a production cell or even as much as $3,500/minute for an entire auto factory line, reducing downtime is critically important. Trying to troubleshoot an equipment problem through pictures via e-mail or waiting for an offsite specialist to travel to the problem site adds costly hours that can be easily avoided with mobile collaboration technologies. Much of this delay can be reduced or eliminated by bringing the problem to the expert, as opposed to the other way around.

IMPROVED SUPPLIER INTERACTION The CPG manufacturer also uses mobile collaboration to streamline supply chain interaction. Design reviews and first-run production samples are an ongoing part of standard communication with suppliers. Normally, team members would travel to the supplier locations for live interactions, introducing delays into the process. Instead of travel, the mobile devices are now kept or shipped to major suppliers to perform live visual communication when needed. The camera optics within these mobile devices are so advanced that remote experts can see detailed design aspects where even a fraction of a millimeter matters. In some cases, thirdparty cameras such as microscopes or borescopes can also be attached to the mobile device to show the remote experts even more detailed visuals. By interacting live with suppliers on the plant floor, this manufacturer has accelerated product delivery, reduced travel costs, and leveraged scarce expert resources in their own company and that of their supply chain partners. The CPG manufacturer also uses mobile collaboration with its OEM vendors to perform acceptance test processes on new pro duction line equipment. The process was traditionally conducted at the supplier site. Multiple skill sets were required to adequately inspect and test the new production line equipment, which equated to teams of people travelling to the supplier’s facility. In many cases, the OEM vendors were not just in the next state, but in another country or continent. June 2011

Plant personnel share video of problematic equipment and discuss solutions with off-site experts.

Screen shot of the video collaboration software.

Instead of sending a team of people, this manufacturer now sends one person with the mobile collaboration device to stream video and interact with colleagues to perform the acceptance test. Expense savings in this application alone have been as high as @50,000 (approximately $67,500) in just one use.

REMOTE PROCESS REVIEWS For global manufacturers with internal or supplier locations around the world, the importance of visual communication becomes even more important to overcome language and cultural barriers. For one supplier to the automotive, aerospace and medical industry, mobile video col-

laboration has helped visually connect engineers in technical centers with plants in locations such as Mexico. In one instance, the manufacturer experienced an abnormally high scrap rate for one of its products. Language barriers and the inability to capture movement made e-mail and phone communication insufficient to resolve the detailed process issues. Instead of sending specialized engineers to Mexico, the manufacturer held a live collaboration session. The team in Mexico streamed video from the plant floor using the mobile device to show the engineering team the existing production process. By Adhesives & Sealants Industry

ADVANCES IN VIDEO COLLABORATION NETWORK REQUIREMENTS While many benefits and cost savings opportunities are related to using mobile video collaboration on the plant floor, it is important to consider the infrastructure requirements. The main requirement is that the mobile devices have either an Ethernet or wireless network connection to access the Internet. Wireless connectivity (i.e., 802.11 b/g) is the most common method used at a manufacturing plant to keep the device mobility level high. While manufacturers have often invested in wireless networks to share equipment sensor data, these networks were not always constructed with video in mind. As a rule of thumb, most manufacturers use video settings for their mobile devices that require approximately 500 kbps of bandwidth at the plant. However, this mobile video collaboration can be successful with less than 500 kbps as well. In other industries, such as oil and gas or mining operations, it is more common to see bandwidth consumption below 128 kbps due to narrow bandwidth backhaul connections. Even with only 128 kbps, mobile collaboration can include live video, voice, telestration, and image sharing between the field technician and the remote expert. For manufacturing plants, though, the additional bandwidth capacity is typically worth the investment.

WIRELESS ALTERNATIVES

The off-site expert views video, photos and drawings to help plant personnel find a solution.

seeing the process live, the specialists identified numerous process errors. They then communicated the problems and corrective action steps during the live collaboration session. To make sure the feedback was clear, the production team in Mexico then showed the remote engineering team the revised process. This collaboration took three hours instead of the estimated three or four days that typically resulted from attempts to correct problems over e-mail or travel. As a result, the scrap rate immediately decreased by 25% after the new process was implemented. 34

INTERNAL EDUCATION With the emerging problem of aging workforces, leveraging scarce expert resources can also be a major concern. For one manufacturer of industrial equipment, this was their top concern. This manufacturer had more people in their company over the age of 50 than under the age of 30. Within five to 10 years, their top experts would retire, leaving their business without adequately trained resources. Mobile video collaboration provided this organization with a way to leverage its scarce expert pool and effectively mentor staff in the field to develop new experts.

Another alternative to consider is the use of 3G or 4G cellular networks through mobile Wi-Fi hotspot devices such as the MiFi or Cradlepoint. By using a hotspot device, a wireless network can be created for the mobile device anywhere there is adequate cellular coverage. For example, heavy industrial equipment manufacturers use cellular connectivity to perform live collaboration from the field when they need help repairing equipment. Deferred collaboration is another possible alternative to a live video session. When access to the Internet isn’t available or other challenges arise, such as problems in connecting with experts due to time zone differences, the video devices can record to a local SD card. The recording can be uploaded to a shared directory for the remote expert to access later, or the device operator can share the recording in a deferred live collaboration session with a remote expert. While the June 2011

recording is playing, both parties can still talk, telestrate and share images in a fully interactive deferred session.

EXTEND EXISTING VIDEO INFRASTRUCTURE For organizations with investments in meeting room video infrastructure such as Cisco TelePresence suites or Tandberg videoconferencing rooms, mobile collaboration solutions become immediate extensions. The mobile devices and collaboration software use the same industry-standard protocols and media Codecs as the room-based video technologies. For manufacturers, that means that these mobile devices can immediately deliver a “live feed” from the plant floor or the field to add value to traditional face-to-face video meetings. In addition to face-to-face video rooms, mobile collaboration sessions can also be shared with multiple experts on their desktop computers. This “one-to-many” experience can be provided in many ways. One method is to simply call another desktop that has the collaboration software loaded. In this case, the additional experts can interact fully with capabilities like telestration and image sharing. Another way is to launch an online meeting tool such as Cisco WebEx. With this method, colleagues, suppliers or customers can be brought in to a collaboration session for ad-hoc meetings very quickly.

MULTIPLE BENEFITS With the advent of mobile technologies, securely extending the power of video collaboration across a manufacturing enterprise is now a reality. Manufacturers have proven that mobile video helps reduce downtime, drive quality improvements, accelerate product delivery, leverage experts and eliminate unnecessary travel. Video is now an essential component of interaction between manufacturing facilities, suppliers, customers and OEM vendors. For many manufacturers, engaging in a video collaboration session has become as simple as making a phone call.

PATENT BASICS A patent protects a company’s innovative technology by creating an intangible asset that, like real estate or equipment, can be bought, sold, or rented. By Rich Ehrlickman, Vice President, General Patent Corp.

patent is a form of intellectual property—and it is often the most misunderstood. For example, take the idea that owning a patent gives you the right to practice (produce or sell) a product or service that uses your patented invention. You do not actually need a patent to practice a new technology that you invented. In fact, the purpose of a patent is to grant you a time-limited monopoly for your invention that prevents others from using it. It is entirely possible, however, that you may need to license a patent from someone else in order to use your new technology if your invention is an improvement to a previous technology. Unless you take a license from the owner of the underlying technology, you could find yourself being sued for patent infringement. There was a time when many patents were issued for totally new technologies, such as the phonograph, telephone and transistor. In today’s complex world of overlapping technologies built on previous technologies, however, it is not uncommon for a new product to infringe the patents of previous technologies. The classic example of this is the person who invents a siren for a fire engine. In order to build and sell fire engines with sirens, that person may have to license the patent for the basic fire engine. If they want their fire engine to have both a siren and a flashing light, they might have to license the patent for the flashing light. However, if they decide to simply manufacture sirens and sell them to the fire engine manufacturers, they don’t need a patent. On the other hand, if they want to prevent others from manufacturing sirens, they do need a patent. Patents are extremely useful to all businesses, whether they’re process manufacturers or producers of discrete products and service organizations. A patent protects a company’s innovative technology by creating an intangible asset that, like real estate or equipment, can be bought, sold, or rented (licensed). A patent enables individual inventors and innovative organizations to invest in research and development, and then have the technology they develop become an asset that produces a return on their investment. The limited monopoly given to patent owners by the federal government is for 20 years from the date of application filing.

U.S. Patent No. 3,691,140, for Acrylate Copolymer Microspheres. This is the adhesive used in Post it® Notes.

PATENT RIGHTS A patent is not needed to produce a product or service that uses the new and unique technology that you invented. (“You” can refer to a person or people working for a company, university or other entity.) Securing a patent only protects your invention by giving you the right to determine who can use your patented invention, and it gives you the right to sue any person, business or other entity that uses your patent without your permission for patent infringement. When a patent is issued by the U.S. Patent and Trademark Office, it identifies the inventor or inventors (the person or June 2011

people who invented the patented technology). The inventor or inventors may assign the patent to another person or entity, such as a business or university. When engineers, scientists, researchers and other innovators invent something while in the employ of a business, university or other organization, the patent is usually assigned to the employer, which then becomes the owner of the patent. Some patents are “basic” and address a fundamental or totally new technology, while others are “improvement” patents that cover enhancements to existing technologies. If you have patents for technologies you are not using, they might have applications in other industries. You could monetize what might otherwise be idle assets by selling or licensing your under-performing or unused patents to non-competing businesses to create a totally new revenue stream. While you may be forced to license your patent to a competitor, licensing unused technology to non-competitors does not create competition for your current products and services. On occasion, companies have managed to cleverly license their current technology to one or more of their competitors just before they introduce a new or improved technology. In this way, their competitors pay them for old technology while the company gains market share and grows its profits with the new technology. If you do business in countries other than the U.S.—and especially if you have competitors in other countries—you might consider patenting your invention in those countries. U.S. patents only protect against infringers that manufacture or sell products in the U.S., or companies that import them into the U.S. If you sell your products in Europe, for example, and you have a competitor in Germany, you may want to apply for a patent in Germany to protect you should your German competitor infringe your patent and begin producing infringing products in Germany. Keep in mind that it is expensive to apply for a patent. It does not usually make sense to apply for a patent in smaller markets such as Portugal or Greece, for example. A recently signed treaty among most of the industrialized nations created the Patent Prosecution Highway (PPH), which makes it easier to apply for patents in several countries. You initially apply in the country where the technology was invented, but you can then use some of the documentation used in your home country application to apply for patents in other countries that are parties to the treaty.

PATENT VS. TRADE SECRET Some inventors question whether they should apply for a patent or simply keep their new technology to themselves as a “trade secret.” The downside of a patent is that it is published. In exchange for the limited monopoly you receive with your U.S. patent, you must make your invention public. In preInternet days, the U.S. Patent and Trademark Office housed June 2011

U. S. Patent No. 5,162,407, for Silicon Rubber Sealant Composition is a good example of an improvement patent. Notice that 25 previous U.S. patents are cited.

patent libraries in federal buildings across the country where one could view all issued patents. While those patent libraries still exist today, most people simply look up patents online. Inventors can bring a new product to market before the patent is issued; once the patent application is filed, the inventor can then mark the products that use the patent as “Patent Pending.” One benefit of this practice is that it might force a competitor to think twice about copying an invention for fear that once the patent is issued, they’ll be sued for patent infringement. If your patent is not issued, however, you need to remove “Patent Pending” from your products and that could cause some embarrassment. A trade secret involves literally keeping your invention a secret. Reasonable precautions need to be taken to ensure that your trade secret remains, well, secret. Examples include limiting access to the technology to as few people as possible, and making sure that drawings, formulas, schematics and other documentation are literally kept under lock and key. Employees who come in contact with the secret technology should sign confidentiality agreements, and details of the secret should only be released on a need-to-know basis. The downside of a patent is that it is published, while a trade secret is not. However, patents provide recourse if someone infringes the patent. On the other hand, if someone cracks your trade secret, reverse-engineers it or simply invents it on their own, you have no recourse against the infringer. Before you make the decision to patent your new technology or keep it as a trade secret, consider how difficult it would be for a competitor to reverse-engineer it and how likely it is that someone might independently invent it.

If you decide to apply for a patent, it can be beneficial to use the services of a patent practitioner, agent or attorney. In order to receive a patent, you must convince the U.S. Patent and Trademark Office that your invention meets the statutory requirements to receive a patent: It must be “novel” (a new invention that did not previously exist), it must be “useful” (have a practical application), and it must be “non-obvious” (not something a “person skilled in the art” would have figured out himself or herself). By “skilled in the art” the patent law means a person with expertise in the technology covered by the patent and a person familiar with all prior art relevant to that patent. Both patent agents and patent attorneys have passed the Patent Office Bar Examination, but a patent attorney is also a member of the bar of one of the 50 U.S. states or the District of Columbia. Patent agents and patent attorneys know the patent application (or “patent prosecution”) process, so they are also referred to as “patent prosecutors.” Whether you choose a patent agent or patent attorney, an experienced patent professional can craft and file your patent application based on your description (and the patent prosecutor’s subsequent understanding) of your invention. The challenge is to have claims that are neither too narrow nor too broad. Your claims may have to be narrow to avoid prior art. Such narrow claims might cover a very specific invention, but could be easy for competitors to work around when designing their own product or process. However, claims that are too broad could result in your patent application being rejected. A competent patent prosecutor should be able to draft patent claims that provide just the right amount of information to support your business and protect against infringers. For the best results, choose a patent practitioner with experience in the same field of technology as your invention. Patent attorneys and patent agents can generally grasp technologies other than their specialties, but choosing a patent practitioner who is already conversant in your area of technology is often a wise investment.

The “prior art” search (also known as a novelty search or patentability search) and its resulting patentability opinion is another important step. This search, which is a good idea though not legally required, consists of combing the Patent Office’s collection of prior patents, published articles, brochures, schematics and other documentation to find information that relates to your invention. The aim of the search is to find evidence that the invention you’re trying to patent either lacks novelty (i.e., it’s not really new) or is obvious in light of what’s been done before. This is not something you want to find, but it is better to discover it before you file your patent application so you can avoid the loss of time, effort, manpower, resources and money that result from having an application rejected.

ENFORCING THE PATENT

Your patent practitioner should have a prior art search conducted. The results help the patent attorney or patent agent focus on the most patentable aspects of your invention. Knowing the prior art enables the patent practitioner to write the claims around previous inventions and avoid the non-novel or obvious aspects of your invention.

It’s important to make sure that your patent has actually been infringed before you take action. It’s not enough that a competitor’s product or process does approximately the same thing as yours; to infringe one of your patent’s claims, the device must meet each and every limitation of that claim. It’s best to have a patent professional take a look at your patent and the allegedly infringing product to determine whether infringement is really taking place. Look for a patent litigator or IP enforcement firm that will take the case on a contingency basis, with no upfront cost to you. Whether you proceed through trial or settle the case, their fees and expenses will come out of the proceeds from the settlement or damages award. Needless to say, a litigator or patent enforcement firm that works on contingency won’t take your case unless they believe it has considerable merit. Should you discover that a person, business or other entity is using your patented invention without a license from you, you might think the logical thing to do is to confront the infringer, threaten a lawsuit, and insist that they either cease their infringing ways or take a license. However, doing so may give them grounds for filing a declaratory judgment lawsuit against you. By filing a preemptory lawsuit against you, the infringing party becomes the plaintiff and you become the defendant. Whenever possible, you want to be the plaintiff so you and your attorney control the timing and location of the litigation, as well as who is sued. As the plaintiff, you can select the venue (location of the court) for the trial, and, in the case

CAN A PROCESS BE PATENTED? One of the biggest controversies about patents in the last few decades concerns “business method” patents and whether or not they should exist. True to their name, these patents generally cover methods of doing business, mostly in fields of industry such as finance, tax compliance, insurance and— more recently and most significantly—e-commerce and the Internet in general, as well as software. Business method patents are not a new phenomenon. The first U.S. patent of this type was granted in 1799 to Jacob Perkins of Massachusetts, who had invented a method of “Detecting Counterfeit Notes.” (Unfortunately for history buffs, the 1836 Patent Office fire destroyed the Perkins patent, along with many others.) Many business methods hover in the gray area of patentability because they would not pass the “machine or transformation test” (MORT), which requires an invention to either be tied to a particular machine or transform an item from one state to another. By that reasoning, process manufacturing methods are usually patentable if they truly transform material from one state to another, and as long as they meet the other previously mentioned patentability requirements.

PATENT BASICS of multiple infringers, you can decide which patent infringement lawsuits will be filed and in what order. Whenever infringers are contacted, they almost always respond in the same way: they insist that they are not infringing your patent and that your patent is not valid anyway. In a declaratory judgment lawsuit, the accused infringer will seek an order from the court declaring that the patent is invalid or not infringed. You will have the opportunity to defend yourself, but by filing the lawsuit first, the infringer is on defense while you are on offense. To achieve the best results when enforcing your patent, find an experienced patent litigator or a patent enforcement firm that has a proven track record of producing settlements for patent owners. Some patent attorneys only prosecute patent applications, while some both prosecute patent applications and are patent litigators. Some patent litigators specialize in litigation, and there are patent enforcement firms that, as the term implies, specialize in the enforcement of patents for inventors and businesses, providing a com-

prehensive package of services that includes managing and financing a patent enforcement campaign on a 100% contingency basis. You may also be entitled to injunctive relief if you practice your patent. If you produce or sell a product or service that uses your patented invention, one remedy that may be available to you—in addition to compensation for the use of your patent without your permission— is a court injunction instructing the infringing party to cease production and sales of the infringing product. In addition, if your legal team can prove willful infringement, you may be entitled to up to treble damages. If you are able to prove infringement of your patent, compensation is based, in part, on what the infringer would have paid you had they licensed your patent in the first place. Just as most civil litigation does not go to trial but is settled out of court, the same is true of most patent infringement lawsuits. Patent infringement lawsuit settlements are often based on a reasonable royalty that is applied to the unit or dollar sales of the infringing product (or some other

measure of the patent’s use). The settlement might include a payment for past infringement of the patent, and then either a license by the infringer under which the infringer (now a licensee) pays a royalty over the remaining life of the patent. Alternatively, the infringer may estimate sales of the infringing product over the remaining life of the patent and settle the lawsuit with a lump-sum payment. The question of enforcement raises a peculiar, but not uncommon, situation. Company A, a small business, owns a patent that is being infringed by Company B, a huge corporation. Does Company A really want Company B to cease production and sales of the infringing product, or is Company A better off letting Company B sell the infringing product so it can collect royalties on all those sales? Patents— as well as politics—can make strange bedfellows.

WHAT’S NEW RAW MATERIALS CRODA POLYOLS

The Priplast range of polyester polyols are highly renewable, bio-based materials that reportedly allow formulators to create environmentally friendly, high-performance polyurethanes with improved performance. Priplast 3238 and Priplast 3286 are two new, 100% bio-based products that can offer increased renewability for green polyurethanes. In laboratory testing, both products reportedly offered excellent durability and moisture repellency. In durability testing, they were able to maintain over 90% of their tensile strength, outperforming PTMEG and HDOadipate. In addition, the products were shown to exhibit lower uptake of water in moisture repellency testing, compared to four other competitive polyols. Web: www.crodacoatingsandpolymers.com

The adhesive reportedly offers the convenience and power of a one-part crosslinking polyvinyl acetate (PVA) emulsion adhesive. It exceeds the requirements of ASTM D 5572 Dry Use Standard and European Standard DIN EN204 D3, and offers heat resistance, enabling bonded stock to withstand high temperatures in the field and during overseas shipping.

AD INDEX

DR.DAVE

QUESTION: We formulate ultraviolet (UV) adhesives using methacrylate monomers. Can you give us some tips on how to maximize the cure speed? ANSWER: Curing can be sped up in several ways. Obviously, using high-energy UV lamps is one way. A judicious choice of photoinitiator and perhaps amine synergists is then essential. While methacrylate monomers have traditionally been used in UV adhesives, the coatings industry has usually used acrylates. Most adhesive formulators chose methacrylates because they produce less brittle adhesives and give higher adhesive strengths, and the monomers are less irritating and toxic than acrylate monomers. However, many of the newer acrylate monomers and oligomers are much safer to use. They can be mixed with methacrylates and can give dramatic increases in cure speed. QUESTION: Can we use anaerobic threadlockers for screws used in plastics?

Many people use

ASK

ANSWER: These materials are cyanoacrylate not normally recommended for use in plastics substrates, adhesives as particularly on thermoplastics. Although some plastics are threadlockers in resistant, many plastics are stress-cracked by the monomers plastics. used in these adhesives. This phenomenon is made worse the longer the liquid threadlocker is in contact with the plastic before it cures to a solid. Unfortunately, plastics are very inactive surfaces for curing threadlockers, which normally require metals to make them cure quickly. This can sometimes be mitigated by using an activator to cure the adhesive. Many people use cyanoacrylate adhesives as threadlockers in plastics. An alternative is to use metal-threaded inserts in the plastics.
