Abstract
The adhesive organopolysiloxane composition contains a compound having two or more allyl ester groups in combination with an adhesion imparting agent of a silicon compound having at least one group selected from the group consisting of an alkoxy group and an epoxy containing hydrocarbon group and also having at least one silicon-bonded hydrogen atom. This composition is markedly improved in adhesion to various substrates and durability of the adhesion.
Claims1
An adhesive organopolysiloxane composition comprising:
- (A) 100 parts by weight of an organopolysiloxane having at least two alkenyl group in its molecule and a viscosity at 25.degree. C. of 100 to 200,000 cSt,;
- (B) an organohydrogenpolysiloxane having two or more silicon-bonded hydrogen atoms in its molecule in such an amount as to supply 0.6 to 6.0 silicon-bonded hydrogen atoms per alkenyl group of said (A) organopolysiloxane;
- (C) a catalytic amount of a platinum catalyst;
- (D) 0.5 to 20 parts by weight of an adhesion imparting agent comprising at least one compound selected from the group consisting of compounds of the formulas:
- ##STR15## and (E) 0.05 to 5 parts by weight of a compound containing two or more allyl ester groups in its molecule.
