DOW CORNING® EA-7100 Adhesive Greatly Expands Design Options, Lowers Total Cost of Ownership for Automotive Electronics
Dow Corning introduced today at the SAE 2015 World Congress (booth 507) new DOW CORNING® EA-7100 Adhesive, a breakthrough silicone chemistry that greatly expands design options for automotive electronics by enabling strong bonds to a wide variety of substrates. This one-part, heat-cure adhesive also cures rapidly and at lower temperatures from the "inside out" to greatly accelerate processing, lower energy use and reduce material costs.
"Building on decades of innovation for advanced automotive electronics, our new EA-7100 Adhesive material signals a significant step forward in silicone technology and an important addition to our industry-leading portfolio of high-performance adhesives," said Brice Le Gouic, global marketing manager for Transportation Electronics, Dow Corning. "Formulated with a patented new silicone chemistry, EA-7100 Adhesive offers significantly broader latitudes when designing next-generation control units, sensors, lighting and display modules targeting today’s increasingly demanding automotive underhood applications."
Notably, new EA-7100 Adhesive forms strong bonds to metals, ceramics, glass and laminates, as well as plastics that have typically presented challenges for conventional silicone, such as polyethylene, polycarbonate and acetal. Depending on application, the material can often bond to these substrates without requiring pre-treatment or extensive cleaning. This unique property, combined with the material’s low voiding and durable adhesion, enables automotive manufacturers to design components using an expanded range of more cost-effective materials.
Fast, Low-Temperature Cure Enhances Productivity and Cost Savings
EA-7100 Adhesive’s radical new chemistry allows up to 50 percent faster cure time than conventional heat-cure platinum catalyzed silicone adhesive systems. Depending on application and processing parameters, it may even achieve higher performance. In a typical lid seal design, for example, a standard one-part addition-cure adhesive generally takes 60 minutes to cure at 125°C. By contrast, DOW CORNING EA-7100 Adhesive achieves full cure within 15 minutes at 100°C. In select applications, cohesive adhesion may begin within three minutes.
Heat can accelerate the cure time for EA-7100 Adhesive, although the material’s advanced chemistry allows the use of smaller, lower temperature ovens that consume less energy and help further lower the total cost of ownership. The material can be dispensed using conventional equipment.
EA-7100 Adhesive has been tested and qualified by leading tier customers worldwide. It is available globally from Dow Corning and its distributors.
