Abstract: Air-drying compositions useful as industrial maintenance coatings are made from aqueous solutions, dispersions or micro-emulsions of the salted reaction products of fatty acids and epoxy-amine adducts plus metal driers.

Abstract: Tertiary amine terminated resinous compositions are prepared by reacting a molar excess of a polyepoxide compound with a dihydric phenol in a large excess of a monoamine which contains one tertiary amine group and one primary hydroxyl group. The resinous composition can be salted with an acid and can be dissolved or dispersed in water. The aqueous dispersions or solutions can be formulated into primer coatings for metal objects.

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.

Abstract: Polyepoxide resins are adducted with amines and the adducts are then reacted with cyclic dicarboxylic acid anhydrides. The resulting resinous products when salted with an amine are water soluble or water dispersible. The resinous solutions or dispersions can be formulated into coating compositions particularly useful for metal substrates.

Abstract: Coating compositions are prepared from aqueous dispersions of polyhydroxy polyether resins and aminoplast or phenolplast resins or blocked polyisocyanates containing as a diluent an aqueous emulsion of a water immiscible alcohol. The coating compositions are particularly useful as can coatings.
