A Highly Dielectric, Non Corrosive, Sealant / Adhesive.
Recommended to us by a customer, we have found GC Electronics Silicone to be just the thing for gluing down IPEX antenna connections, creating wiring strain reliefs and even using it as an electrical insulator & sealant.

GC Electronics Silicone is a one part, non-corrosive electronics grade silicone sealant. It is an excellent adhesive for many electrical and electronic applications where corrosion is a problem with metals -- particularly copper, brass, silver, etc..
