ABSTRACT:
Water dispersible epoxide resin compositions are made by reacting a diglycidyl ether of a dihydric phenol with a dihydric phenol and a co-reactive urethane surfactant. The co-reactive surfactant is prepared by reacting a long chain aliphatic polyether glycol with a diisocyanate and a dihydric phenol in a molar ratio of 1/X/X wherein X has a value of 2 to 6. Aqueous dispersions of the water dispersible epoxide resin composition can be formulated into coating compositions.
