ABSTRACT:
A low modulus, one component, room temperature vulcanizable silicone elastomer which has very good oil resistance properties as well as high elongation. The silicone elastomer which has low volatility comprises a silanol terminated diorganosiloxane base polymer, a trimethylsilyl terminated diorganopolysiloxane, generally a tin catalyst, as well as a oxime crosslinking agent and specific low moisture fillers, usually calcium carbonate. The material is ideally suited as a gasket sealant as well as a formed-in-place gasket and can be utilized on internal combustion engines such as automotive engines as a sealant for an oil pan, valve cover, side seals and the like.
