Dielectric Grease

MG Chemicals’ dielectric grease is a thick gel that offers premium protection against moisture, corrosion, and electrical arcing. Because of their extreme hydrophobicity, dielectric greases are used in a wide range of applications where ruggedization of electronics is required. Specifically, when dielectric grease is applied to electrical connections, it protects them from moisture damage. Also, thanks to its high electrical resistance, dielectric grease can be applied to pin connectors to prevent shorting.
