RTV silicone (room-temperature-vulcanizing silicone) is a type of silicone rubber that cures at room temperature. It is available as a one-component product, or mixed from two components (a base and curative). Manufacturers provide it in a range of hardnesses from very soft to medium—usually from 15 to 40 Shore A. RTV silicones can be cured with a catalyst consisting of either platinum or a tin compound such as dibutyltin dilaurate.[1] Applications include low-temperature over-molding, making molds for reproducing, and lens applications for some optically clear grades.[2] It is also used widely in the automotive industry as an adhesive and sealant, for example to create gaskets in place.
