Organopolysiloxane composition
First Claim
1. An organopolysiloxane composition comprising:
- (A) 100 parts by weight of an organopolysiloxane represented by formula (1) shown below wherein, each R1 represents, independently, either one of a substituted and an unsubstituted monovalent hydrocarbon group of 1 to 15 carbon atoms, and a represents an integer from 10 to 3000;
(B) 0.1 to 30 parts by weight of an organosilicon compound represented by a formula (2) shown below wherein, each R2 represents, independently, any one of a hydrogen atom, a phenyl group and a halogenated phenyl group, each R3 represents, independently, either one of a hydrogen atom and a methyl group, each R4 represents, independently, either one of a substituted and an unsubstituted monovalent hydrocarbon group of 1 to 10 carbon atoms, X represents a hydrolysable group, each Z1 represents, independently, any one of —
R5—

R5O— and
—
R5(CH3)2SiO—
where each R5 represents, independently, either one of a substituted and an unsubstituted bivalent hydrocarbon group of 1 to 10 carbon atoms, Z2 represents any one of an oxygen atom, and a substituted and an unsubstituted bivalent hydrocarbon group of 1 to 10 carbon atoms, m represents any one of 0, 1 and 2, and n represents any one of 0, 1 and 2;
(C) an effective quantity of a condensation curing catalyst; and

Abstract
An organopolysiloxane composition is provided including: (A) an organopolysiloxane with hydroxyl groups at both terminals of the molecular chain; (B) an organosilicon compound represented by the general formula shown below:
wherein, R2 represents a hydrogen atom, a phenyl group or a halogenated phenyl group, R3 represents a hydrogen atom or a methyl group, R4 represents a monovalent hydrocarbon group, X represents a hydrolysable group, Z1 represents —R5—, —R5O— or —R5(CH3)2SiO— (wherein R5 represents a bivalent hydrocarbon group), Z2 represents an oxygen atom or a bivalent hydrocarbon group, m represents 0, 1 or 2, and n represents 0, 1 or 2; (C) a condensation curing catalyst; and (D) a photopolymerization initiator. This composition has two curing mechanisms, namely photopolymerizability and condensation curability, and displays superior adhesiveness, and in particular displays favorable adhesiveness to a substrate immediately following irradiation with ultraviolet light.
