Stable aqueous epoxy resin dispersions are made from a self-emulsifying epoxy resin film forming component which is the reaction product of a diglycidyl ether of a dihydric phenol, a dihydric phenol, a diglycidyl ether of a polyoxyalkylene glycol and a diisocyanate. The dispersion also contains a water-immiscible aliphatic monoepoxide and a water-miscible organic solvent. The dispersions will cure with epoxy resin curing agents to form coatings for industrial uses.
