METHOD OF ADHERING TOGETHER THERMOPLASTIC RESIN SUBSTRATE AND ORGANOPOLYSILOXANE RESIN

摘要

PROBLEM TO BE SOLVED: To provide a method of adhering together a thermoplastic resin substrate and an organopolysiloxane resin together which provides a good laminate structure excellent in heat resistance and durability and does not produce warp.SOLUTION: A method of adhering together a thermoplastic resin-made substrate and a hardened product of an organopolysiloxane resin includes a step of applying a UV-curable organopolysiloxane resin composition comprising (A) (A-1) a linear organopolysiloxane having two or more alkenyl groups bonded to Si in one molecule and (A-2) a three-dimensional netlike organo polysiloxane resin containing RRSiOunits, RSiOunits and SiOunits, (B) an organohydrogenpolysiloxane, (C) a photo-active type platinum complex hardening catalyst and (D) an organopolysiloxane oligomer onto a thermoplastic resin-made substrate for lamination to form a laminate of the thermoplastic resin-made substrate and the unhardened organopolysiloxane resin composition and irradiating the laminate with UV rays from the outer surface of the organopolysiloxane resin composition to harden the organopolysiloxane resin composition.
