Shin-Etsu Silicones Introduces KER-4410/KER-4400

In an effort to advance silicones for LiDAR and related automotive sensor applications, Shin-Etsu Silicones of America, Inc., Akron, Ohio, (SESA: A US subsidiary of Shin-Etsu Chemical Co. Ltd., Japan) is introducing a UV-Activated Dual-Cure Silicone Series, which includes KER-4410 and KER-4440 as the focal points.

Silicones contain compounds that feature a main chain of siloxane bonds, which provide distinct advantages over epoxy alternatives including heat stability, cold resistance, stress releasing, no curing shrinkage and addition/radical polymerization.

Essentially, the adhesive is applied, exposed to UV, the sensors or components are placed on the board and then other board processes can be conducted in parallel. This dual-cure system saves processing time, requires no need for ovens at high temperatures, doesn’t shrink during curing (vs. epoxies) and delivers no added stress.
