ABSTRACT:
A room temperature vulcanizable composition comprises a diorganopolysiloxane blocked with a silanol group at both ends of the molecular chain, an organopolysiloxane having at least three silanol groups in the molecule, and at least one member selected from the group consisting of organosilanes and organopolysiloxanes each having two hydrolyzable groups in one molecule. The composition ensures easy control of its working life and is able to yield a cured product having a low modulus over a long time.
