Liquid, solvent-free, non-toxic stabilizers for vinyl chloride resin compositions comprise a major amount of a liquid epoxy compound and minor amounts of magnesium, zinc, and calcium salts of alkanoic acids having 6 to 26 carbon atoms, an organosulfur compound, and an organic phosphite. Vinyl chloride resin compositions that contain these stabilizers are characterized by excellent heat and light stability, color, and clarity.

Liquid, solvent-free, non-toxic stabilizers and vinyl chloride resin

Surface-coating compositions that comprise an oxidizable organic film-forming resinous vehicle containing from 0.5% to 5.0%, based on vehicle solids, of a loss-of-dry inhibitor that is a suspension of finely divided calcium hydroxide in a solution containing at least one calcium salt of a branched-chain aliphatic monocarboxylic acid having 6 to 14 carbon atoms, a cycloaliphatic monocarboxylic acid having 6 to 10 carbon atoms, or a mixture of these acids.
