An auto-adhering one-component room temperature vulcanizable silicone sealant composition generally utilizing a di-substituted mixed oximealkoxysilyalkyl area adhesion promoter compound. The sealant has low odor, is non-corrosive to ferrous or aluminum substrates, has good adhesion to many types of substrates, and eliminates the need for a silicone resin primer. In addition, it exhibits surprisingly good adhesion to oil contaminated surfaces.

An auto-adhering one-component room temperature vulcanizable silicone sealant utilizes a gylcidoxyalkyl substituted mixed alkoxy-oxime silane as an adhesion promoter. The sealant bonds to a variety of substrates including glass, metal, ceramics; does not require a primer to be applied to the substrate; has a low odor and is non-corrosive to ferrous substrates. The sealant is useful as a formed-in-place gasket material as for example, an internal combustion engine and has good oil resistance for an RTV silicone gasketing material.

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.
