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.
