Abstract
A composition useful as a liquid gasket, having high working efficiency and high initial pressure resistance, is provided. The composition, characterized by being curable by ultraviolet light and by moisture, includes (a) a polysiloxane containing, on at least one molecular end, at least one group selected from the group consisting of (meth)acryl, glycidyl, propenyloxysilyl and thiol; (b) a polyorganosiloxane having silanol groups at both molecular ends; (c) a polyorganosiloxane having, on at least one molecular end, a hydrolyzable group; (d) a photopolymerization catalyst; and (e) a condensation catalyst.
