Abstract
Sanitary coatings based on self-emulsifiable epoxy ester copolymers are produced by esterifying a solvent-soluble carboxyl polymer with an epoxy resin in an organic resin and in the presence of at least about 2% amine catalyst to provide a carboxyl-functional epoxy polymer which can be reacted with a base and dispersed into water.
