Abstract
A curable composition including (A) 100 parts by weight of an organic polymer having at least one cross-linkable group containing a silicon atom to which a hydrolyzable group is bonded, and (B) 10 to 500 parts by weight of a vinyl chloride polymer. In the curable composition of the present invention, the viscosity is not lowered even after the storage for a long time and therefore the workability as sealants is not lowered.
Claims5
A curable composition comprising,
- (A) an organic polymer having in its molecule at least one cross-linkable group containing a silicon atom to which a hydrolyzable group is bonded, said cross-linkable group being cross-linkable to produce an elastomer by the formation of a siloxane bond,
- (B) 50 to 300 parts by weight of particles of a vinyl chloride paste resin per 100 parts by weight of said organic polymer (A), said vinyl chloride paste resin particles being present in said composition as a filler, and
- (C) a plasticizer for vinyl chloride paste resin;
- said vinyl chloride paste resin being partially gelatinized with said plasticizer.
