Patent ID: 7723442

Claim:
A room temperature curable organopolysiloxane composition, comprising: (A) 100 parts by mass of an organopolysiloxane represented by formula (2) wherein each R 1 represents, independently, an unsubstituted or substituted monovalent hydrocarbon group of 1 to 10 carbon atoms; each R 2 represents, independently, an unsubstituted or substituted monovalent hydrocarbon group of 1 to 6 carbon atoms; n represents an integer of 10 or greater; and m and L each represent an integer of 0 or 1; (B) 0.1 to 30 parts by mass of a silane compound and/or a partial hydrolysis-condensation product thereof containing an average of at least two hydrolysable groups selected from the group consisting of ketoxime groups, alkoxy groups and isopropenoxy groups bonded to silicon atoms within each molecule, and in which remaining groups bonded to silicon atoms are selected from the group consisting of a methyl group, ethyl group, propyl group, vinyl group, and phenyl group; and (C) 0.1 to 10 parts by mass of either one, or two or more organosilicon compounds represented by formula (3) wherein R 2 is as defined above; each R 3 represents, independently, a bivalent hydrocarbon group of 1 to 10 carbon atoms; R 4 represents a bivalent hydrocarbon group of 1 to 10 carbon atoms; p, q, and r each represent an integer of 0 or 1; q′ represents an integer of 2 or less; and q+q′ represents an integer of 2 or less.
