RTV Silicone Rubber

RTV Silicone Rubber (Room Temperature Vulcanizing) are a group of silicone compounds whose vulcanization process takes place at room temperature and depending on the vulcanization mechanism, they are produced by condensation and hydro silylation in one-component and two-component ways.

In single-component systems, the curing mechanism is based on condensation reactions and occurs in the presence of atmospheric moisture, while in two-component systems, based on condensation reactions, the main component is polydimethylsiloxane containing hydroxyl groups at the end of the chain and the secondary component includes the crosslinking agent. usually alkoxy silane) and is sensitive to hydrolysis. In two-component systems based on hydro silylation, one of the components contains vinyl groups at the end of the chain, and the other component contains a crosslinker, usually polymethyl hydrogen siloxane or copolymers with dimethyl siloxane bridge structures.
