Abstract
A novel primer composition, which is especially adapted for promoting the adhesion of thermosetting rubbers to substrates having exceptionally inert surfaces, such a nickel, stainless steel and organic resins is disclosed. The composition comprises: (A) 100 parts, by weight, of an organosilicon compound selected from the group consisting of (1) alkenyltrialkoxysilane and (2) mild hydrolyzates of (1); (B) 0.01-200 parts, by weight, of a platinum compound; (C) 0.1-100 parts by weight of an organic titanic acid ester; and optionally (D) a solvent.

A primer composition comprising:
- (A) 100 parts by weight of an organosilicon compound selected from the group consisting of:
- (1) an alkenyltrialkoxysilane having a general formula:
- RSi(OR.sup.1).sub.3, wherein R is an alkenyl group with at least 3 carbon atoms and R.sup.1 is selected from the group consisting of alkyl groups and alkoxylated alkyl groups;
- and
- (2) mild hydrolyzates of (1);
- (B) 0.01-200 parts by weight of a platinum compound;
- and
- (C) 0.1-100 parts by weight of an organic titanic acid ester, and
- (D) 10-10,000 parts by weight of a solvent selected from the group consisting of organic solvents and silicone solvents.
