Abstract:
1. A room temperature curable organopolysiloxane composition comprising: (A) 100 parts by weight of a diorganopolysiloxane represented by a general formula (1) shown below: (wherein, each Y represents a hydroxyl group, and each R represents, independently, an unsubstituted or substituted monovalent hydrocarbon group, each X represents, independently, either an oxygen atom or a bivalent hydrocarbon group of 1 to 8 carbon atoms, each a represents, independently, an integer from 1 to 3, and n represents a number which results in a viscosity at 25° C. for said diorganopolysiloxane within a range from 100 to 1,000,000 mm 2 /s, (B2) a compound which, via a hydrolysis reaction, yields: (B1) at least one amine compound selected from the group consisting of amine compounds represented by a general formula (2) shown below: (wherein, R 1 represents a monovalent hydrocarbon group of 12 to 30 carbon atoms, and amine compounds represented by a general formula (3) shown below: (wherein, R 2 represents a bivalent hydrocarbon group of 4 to 30 carbon atoms), wherein a quantity of said compound (B2) is sufficient to generate, on hydrolysis, from 0.1 to 20 parts by weight of said component (B1), (C) an effective quantity of a cross-linking agent, and (D) an effective quantity of curing catalyst.
