The present invention is directed to a two component industrial maintenance coating. The first component is a polyamine terminated epoxy resin which is end capped with a monoepoxide. The second component is a low molecular weight polyepoxide crosslinker. When salted with an acid, the adduct can be dissolved or dispersed in water. The polyepoxide crosslinker can then be microemulsified in the system. When coated on a substrate, the two component mixture cures at room temperature producing coatings having excellent balance of chemical and physical properties.
