ABSTRACT:
Linear polyester resins, terminated with carboxyl groups, and suitable for inclusion in heat-curable fluid coating compositions, are advantageously modified by capping a minor fraction of the carboxyl groups with a hydrocarbyl glycidyl ether. The capped resins produce water-reducible formulations that exhibit a fast curing rate and excellent adhesion when formulated with hexamethoxymethylmelamine, for example. Such fluid coating compositions may be used as industrial coatings and coil-coatings.
