It has been found that non-blushing coatings of high gloss, long pot life and fast cure time may be obtained by using an epoxy curing agent which comprises an epichlorohydrin-metaxylylenediamine reaction product selected from the group consisting of N,N'-bis(3-aminomethylbenzyl)-2-hydroxytrimethylenediamine, the higher oligomers of N,N'-bis(3-aminomethylbenzyl)-2-hydroxytrimethylenediamine and mixtures thereof and a melting point depressant such as a benzyl alcohol or water and an alcohol solvent and, optionally, a tertiary amine such as N,N'-bis(3-(dimethylamino)propyl)-urea.

Epoxy curing agent comprising a metaxylylenediamine-epichlorohydrin

Self-dispersing curable epoxy resin ester dispersions prepared by a process comprising reacting a self-dispersing curable epoxy resin based on a polyoxyalkyleneamine with a fatty acid selected from the group consisting of drying oil and semi-drying oil fatty acids, are provided. The self-dispersing curable epoxy resin is based on a polyoxyalkyleneamine. Thus, a polyoxyalkyleneamine was present as a chemical precursor of the epoxy resin or a starting material therefor. The self-dispersing curable epoxy resin ester of the invention is in the form of an aqueous dispersion. When dried, films of the self-dispersing curable epoxy resin ester dispersion are useful as a coating composition.
