Abstract
The potlife of an ambient temperature, moisture-curable coating composition comprising an acrylic-silane interpolymer and a cure-accelerating catalyst is increased by the addition to the composition of from about 0.5 percent to about 15 percent by weight of interpolymer solids of a monomeric hydrolytically reactive organo-silicon compound represented by the structural formula: EQU X.sub.n Si(OR).sub.4-n wherein X is an organic radical having from 1 to 12 carbon atoms, R is methyl, ethyl, 2-methoxyethyl, 2-ethoxyethyl, or an acyl group containing 5 or less carbon atoms and n is 0, 1 or 2.
