Abstract
A silicone rubber adhesive composition comprising (A) a heat curable organopolysiloxane composition of the addition curing type or peroxide curing type, (B) reinforcing silica fines, (C) an adhesive agent, and (D) an organosilicon compound having a functional group reactive with component (A) and a siloxane skeleton incompatible with component (A) is easily moldable within a short time by injection molding, suitable in primerless molding, and bondable with various thermoplastic resins. Integrally molded articles in which the silicone rubber adhesive composition is firmly bonded to the thermoplastic resin are obtainable without a need for modification of the resin.

A silicone rubber adhesive composition comprising
- (A) 100 parts by weight of a heat curable organic peroxide curing type organopolysiloxane composition,
- (B) 1 to 100 parts by weight of reinforcing silica fines,
- (C) 0.1 to 50 parts by weight of an adhesive agent, and
- (D) 0.05 to 20 parts by weight of an organosilicon compound having a functional group reactive with component (A) and a siloxane skeleton incompatible with component (A).
A silicone rubber adhesive composition comprising
- (A) 100 parts by weight of a heat curable addition curing type organopolysiloxane composition,
- (B) 1 to 100 parts by weight of reinforcing silica fines,
- (C) 0.1 to 50 parts by weight of an adhesive agent, and
- (D) 0.05 to 20 parts by weight of an organopolysiloxane having a siloxane skeleton incompatible with component (A) in which at least one of entire substituents bound to silicon atoms in its siloxane skeleton is a reactive functional group capable of crosslinking reaction with a polysiloxane component constituting the organopolysiloxane composition (A) and the remaining groups bound to silicon atoms are substituted or unsubstituted monovalent hydrocarbon groups other than said reactive functional group.
