Abstract:
1. A primer composition for assisting in integral molding of a silicone rubber and an adherend, comprising (A) 10 parts by weight of a compound comprising at least one epoxy group, at least one Si—H group, and at least one aromatic ring per molecule, (B) 1 to 100 parts by weight of a silicone resin, (C) 1 to 100 parts by weight of an organooxy group-comprising organosilane compound of the average compositional formula (1): wherein R 1 is a substituted or unsubstituted, monovalent hydrocarbon group, R 2 is a monovalent organic group having an epoxy, (meth)acrylic, amino or mercapto functional group, R 3 is a substituted or unsubstituted, monovalent hydrocarbon group, a, b and c are numbers satisfying 0≦a≦3, 0≦b≦3, 0<c≦4, and 0<a+b+c≦4, and/or a partial hydrolytic condensate thereof, (D) 0 to 100 parts by weight of a condensation catalyst, and (E) a solvent.
