Abstract
Abstract A one component room temperature setting composition having an excellent storage stability comprising a hydrolyzable silyl group-containing vinyl polymer, a hardener and a stabilizer selected from a hydrolyzable ester compound and a 0-diketone compound, which may further contain a pigment and a solvent. The storage stability of the composition containing the hydrolyzable silyl group-containing vinyl polymer which is crosslinkable in the presence of water to harden at room temperature, can be remarkably improved by the presence of the above stabilizer.
