Patent ID: 8247516

Claim:
A room-temperature curable organopolysiloxane composition comprising: (A) 100 parts by mass of a diorganopolysiloxane capped at both molecular terminals with trialkoxysilyl groups and having viscosity of 100 to 1,000,000 mPa·s at 25° C.; (B) 0.1 to 20 parts by mass of a diorganodimethoxysilane of the general formula given below or a partially hydrolyzed product thereof: R 1 2 Si(OCH 3 ) 2 where R 1 s are the same or different, and designate substituted or unsubstituted monovalent hydrocarbon groups; (C) 0.1 to 20 parts by mass of a diorganodialkoxysilane of the general formula given below or a partially hydrolyzed product thereof: R 2 2 Si(OR 3 ) 2 where R 2 s are the same or different, and designate substituted or unsubstituted monovalent hydrocarbon groups, and R 3 s designate the same or different alkyl groups with two or more carbon atoms; and (D) 0.1 to 10 parts by mass of a titanium chelate catalyst, wherein the quantitative ratio of component (B) to component (C) ranges from 1:20 to 5:1.
