Abstract
Abstract A one-pack composition which comprises a silyl group containing polymer in which the backbone is substantially composed of a vinyl type polymer chain and which contains at least one silicon atom attached to a hydrolyzable group at the terminal or in a side chain in the molecule (A), a curing catalyst (B) and a solvent (C). This composition has good workability in a painting stage, excellent weather resistance and weather resistance after coating and curing, and high hardness of the coated surface.
