Abstract
Esters of glycidyl polyethers of saturated phenols are especially useful in coating compositions having a low organic solvent content. The esters are the reaction products of from about 0.5 to about 1.5 equivalents of a saturated monocarboxylic acid with each epoxy group in a diglycidyl polyether of phenols where the aromatic rings of the phenols are saturated.
Claims17
A reaction product of from about 0.5 to about 1.5 equivalents of a saturated monocarboxylic acid with each epoxy group in a diglycidyl polyether of hydrogenated dihydric phenols.
A coating composition consisting essentially of:
- (a) from about 5 percent to about 90 percent of the reaction product of from about 0.5 to about 1.5 equivalents of a saturated monocarboxylic acid with each epoxy group in a diglycidyl polyether of hydrogenated dihydric phenols;
- and
- (b) from about 5 percent to about 80 percent of a crosslinking agent selected from the group consisting of aminoplasts, isocyanates, blocked isocyanates, phenoplasts and mixtures thereof.
