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.
