The All NEW Dow Corning EA-7100 Thermal Radical Cure Adhesive Widens Automotive Electronics Designs
Dow Corning EA-7100 thermal radical cure adhesive is a non-flowing, one component silicone enabling design flexibility due to strong adhesion to a wide variety of substrates. The main application this material is well suited for includes automotive electronic control units, sensors, lighting or display modules applications where lid seal, base plate attaching, gasketing or connector sealing. Some of the many substrates that Dow Corning EA-7100 has excellent adhesion to include epoxy, liquid crystal polymer, phenolic, poly, polyamide, polybutylene terephthalate, most metals and cured silicone and much more.
Viscosity of Dow Corning EA-7100 Adhesive is 360,000 cP and the thixotropy is 5.8. Pre-assembly time at 25°C is approximately 60 minutes and assembled pre-cure time at the same temperature is 24 hours. This advance product can also be heat cured at 100°C for 15 minutes. Specific gravity of the cured adhesive is 1.09 and the tensile strength is 490 psi. This material provides high adhesion to a wide variety of materials as well as offering excellent dielectric properties. Dielectric strength is 437 volts/mil and the dielectric constant at 100 Hz is 2.96. Dissipation factor at 100 Hz is 0.002.
Dow Corning EA-7100 Thermal Radical Cure Adhesive Resources:
The product tends to cure in the bulk and at the bond line first. Outer material will take a little longer to solidify. Dow Corning EA-7100 has a built in secondary moisture cure that enhances the adhesion and completes the cure at the outer surface. Tackiness is typically gone within 24 to 48 hours after heat cure. Operational temperature of the adhesive will be in the range from -45 to 200°C for an extended period of time. Once the temperature is above or below the operational temperature the behavior of the materials performance may become complex and need further consideration. Thermal cycling to conditions as low as -55° C is possible, but performance should be verified for your parts or assemblies. Dow Corning silicone adhesives are typically supplied in 1, 8 and 40lb containers, net weight.
It is strongly recommended to no handle the material until all the information is read and understood on the Dow Corning EA-7100 MSDS. The adhesive is only able to withstand a splash or intermittent exposures to liquid, vapor solvent or fuel. Testing should be done to confirm performance of the adhesive under these conditions. Shelf life and storage methods will be displayed clearly on the label. This product has not been tested nor deemed suitable for pharmaceutical or medical uses. Any questions on the product, contact Krayden and a technical representative will assist in answering any questions that you may have.
