The crosslinking agent used in RTV silicone systems consists of a species that can be represented as R-Si-X3 (typically used in one component systems) or Si-X4 (typically used in two component systems). The R is an organic group such as a methyl, ethyl, or vinyl, and the X is a moisture hydrolysable group. A simplified cure mechanism for a one-component silicone RTV sealant is shown in below:
