  • Loss-of-dry inhibitors for surface-coating compositions
    Patent number: 3972825
    Abstract: Loss-of-dry inhibitors for surface-coating compositions containing oxidizable organic vehicles comprise metal salt solutions that contain 0.05 to 1.5% by weight of cobalt, 0.5 to 3.5% by weight of calcium, and 0.5 to 5.0% 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.
