Patent ID: 7754829

Claim:
A room temperature-curable organopolysiloxane composition comprising (A) 100 parts by weight of an organosiloxane polymer comprising R 3 SiO 1/2 units and SiO 4/2 units wherein R is each independently a substituted or unsubstituted monovalent hydrocarbon group of 1 to 6 carbon atoms, a molar ratio of R 3 SiO 1/2 units to SiO 4/2 units being from 0.6 to 1.2, and the polymer contains less than 0.04 mole of hydroxysilyl groups per 100 grams of the polymer, (B) 50 to 150 parts by weight of at least one member selected from polysiloxanes having the general formulae (1) to (3): wherein R is as defined above, R 1 is each independently an alkyl group of 1 to 6 carbon atoms or alkoxyalkyl group of 2 to 10 carbon atoms, R 2 is each independently a substituted or unsubstituted monovalent hydrocarbon group, R 3 is an alkylene group of 1 to 12 carbon atoms, m is an integer of 1 to 3, n is an integer of at least 1, j is an integer of at least 10, and h is an integer of at least 2, (C) 0.01 to 10 parts by weight of a cure catalyst, and (D) 0.1 to 10 parts by weight of α-trimethoxysilyldecane.
