ABSTRACT:
A process for preparing water-dilutable, heat-curing coating compositions comprises (a) reacting an aromatic polyglycidyl ether with a compound containing an active hydrogen followed by the addition of ethylene oxide to form an adduct containing hydroxyl groups, (b) adding an aminoplast curing agent, and (c) diluting with water to give a stable aqueous composition.
The process gives compositions which are useful in preparing coatings for a wide variety of substrates obviating the need for organic solvents with their inherent costs and environmental hazards.
