Abstract: Polyglycidyl amines having room temperature latency when blended with curing agents and high heat distortion temperatures when cured are derived from hindered aromatic diamines and epihalohydrins. Cured products obtained from these polyglycidyl amines and curing agents are useful in structural composites, film adhesives, molding compounds and the like.

Abstract: The present invention provides a two component resin coating system which when mixed forms a curable coating composition. The first component comprises a polyamine terminated polyepoxide adduct which has been salted with a controlled amount of acid. The salted product is dissolved in a co-solvent having a specifically defined solubility parameter polar component and water. The second component comprises a low molecular weight water insoluble polyepoxide crosslinker which is optionally dissolved in the selected co-solvent. When the two-components are blended together, the polyepoxide resin crosslinker is dispersed in the microemulsified state throughout the salted adduct solution and the resulting composition exhibits improved pot life, freeze thaw stability, and film forming properties.

Abstract: 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.
