ABSTRACT:
The present invention is directed to a thermosetting coating composition for improving the scratch resistance, blush resistance, and lubricity of glass surfaces (e.g., glass bottles), and in certain instances also improving the label adhesion of coatings derived therefrom which comprises as functional ingredients a polyamine terminated polyepoxide adduct salt, an epoxy crosslinker, a reactive silane, a surfactant, and a natural or synthetic wax. The coating composition is carried in a vehicle which comprises water and a suitable co-solvent. The combination of the adduct salt and co-solvent permits the microemulsification of the epoxy crosslinker. The wax is also present in the emulsified state.
