Abstract
Phenolic curing agents, especially suitable for use in powder coatings, are prepared by reacting a dihydric phenol (diphenylol propane), a diepoxide (liquid diglycidyl ether of diphenylol propane), and a dicarboxylic acid (adipic acid) with the phenolic functionality in excess over the difference between the epoxy functionality and the acid functionality.
