<p>A room-temperature curable organopolysiloxane composition comprising: (A) 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) a diorganodimethoxysilane or a partially hydrolyzed product thereof; (C) a diorganodialkoxysilane having silicon-bonded alkoxy group with two or more carbon atoms or a partially hydrolyzed product thereof; and (D) a titanium chelate catalyst, exhibits excellent storage stability and easiness of controlling curing speed as well as by strong adhesion to a substrate with which this composition is in contact during curing along with the possibility of interfacial peeling of the cured product from the aforementioned substrate.</p>
