Abstract
It is the subject of the present invention to provide a solvent-free ambient-temperature curable composition, excellent in water-resistant adhesion, storage stability and curability, and generates neither smoke nor odor when working therewith. The relevant problem is solved by a curable composition including (A) a natural asphalt and/or petroleum asphalt, (B) a polyoxyalkylene polymer having one or more reactive silicon groups capable of cross-linking by forming siloxane bonds through silanol condensation reaction.

A curable composition comprising:
- (A) a natural asphalt and/or petroleum asphalt, and
- (B) a polyoxyalkylene polymer having one or more reactive silicon groups represented by the following general formula (1):
- —Si(R13−a)Xa (1)
- wherein R1 represents an alkyl group having 1 to 20 carbon atoms, an aryl group having 6 to 20 carbon atoms, an aralkyl group having 7 to 20 carbon atoms or a triorganosiloxy group represented by (R′O)3Si—, where, when two R1s are present, they may be the same or different, and R′ is a monovalent hydrocarbon group having 1 to 20 carbon atoms, and three R's may be the same or different;
- X represents a hydroxy group or a hydrolyzable group, where, when two or more Xs are present, they may be the same or different;
- and a represents 1, 2 or 3;
- and
- wherein the (B) component has one or more groups represented by the following general formula (4):
