Self-dispersing curable epoxy resins, dispersions made therewith, and coating compositions made therefrom |
摘要 |
A method of preparing a self-dispersing epoxy resin composition is provided. The method comprises reacting a polyepoxide with a polyoxyalkylene polyol wherein the equivalent ratio of epoxide groups of said polyepoxide to hydroxyl groups of said polyoxyalkylene polyol is greater than 10:1, to form an polyol-epoxy adduct and reacting said polyol-epoxy adduct with a polyepoxide and a polyhydric alcohol to form a self-dispersing epoxy resin. Also provided are aqueous dispersions of the self-dispersing epoxy resin and coating compositions comprising the same. The coating compositions are particularly useful as industrial maintenance coatings.
