Abstract
A one component moisture curable composition containing (A) a hydrolyzable silyl group-containing vinyl polymer and (B) an acid phosphoric compound having ##STR1## linkage in the molecule as a hardener, which has excellent recoatability, curing property and adhesion to other paint films and is particularly suitable as a coating composition for use in multicoat coating.
Claims9
A one component curing composition comprising (A) a vinyl polymer having on the main polymer chain end or a side chain thereof at least one silyl group containing a silicon atom to which a hydrolyzable group is linked, per one polymer molecule, the main chain of the vinyl polymer consisting essentially of a polymer of a vinyl monomer, and from 0.01 to 10 parts by weight of (B) an acid phosphoric compound containing a ##STR9## linkage in the molecule per 100 parts by weight of the vinyl polymer (A);
- said acid phosphoric compound being a compound of the formula:
- ##STR10## wherein n is 1 or 2 and R is an organic residue or a titanate coupling agent containing the ##STR11## linkage in the molecule.
