Abstract
Abstract Surface-coating compositions that comprise an oxidizable organic film-forming resinous vehicle contain from 2 to 5 percent, based on vehicle solids, of a loss-of-dry inhibitor which is a metal salt solution that contains 0.05 to 1.5 percent by weight of cobalt, 0.5 to 3.5 percent by weight of calcium, and 0.5 to 5.0 percent by weight of zinc or zirconium. The metals are present in the loss-of-dry inhibitor as salts of branched-chain aliphatic monocarboxylic acids having 6 to 14 carbon atoms, cycloaliphatic monocarboxylic acids having 6 to 10 carbon atoms, or mixtures of these acids.
