Dow Corning EA-7100 Thermal Radical Cure Adhesive Guide

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.
