Room temperature vulcanization sealant is a type of silicone rubber sealant with strong mechanical properties. Mechanics commonly use it for gaskets, adhesives and caulking. It is possible to apply RTV silicone sealant to glass, metal and elastic surfaces.
Users can apply RTV silicone sealant at subzero temperatures. It cures quickly at room temperature. It is chemical, water and heat resistant, so mechanics can use it on engines and other harsh environments. RTV silicone is a strong rubber with high tear strength. It is usually available in a squeezable or caulk gun tube. Various mixtures of RTV sealant are available that have been designed to perform better in certain environments.
