| 摘要 |
The invention is a water dispersible epoxy resin composition comprising: (A) the reaction product of; (i) one or more polyepoxides; (ii) optionally, one or more poly(aromatic hydroxy) containing compounds, (iii) optionally, one or more chain terminators; and (iv) one or more nominally difunctional C12-36 fatty acids or a dimer of an unsaturated, fatty acid, and B) a sufficient amount of a surfactant to form a stable dispersion of the epoxy resin in water wherein the surfactant comprises an alkyl aryloxy poly(propyleneoxy) poly(ethyleneoxy) ethanol, a C12-36 hydrocarbyloxy poly(propyleneoxy) poly(ethyleneoxy) ethanol or a C12-36 hydrocarbylcarboxyloxy poly(propyleneoxy) poly(ethyleneoxy) ethanol. In another aspect the invention is a high solid aqueous emulsion of such epoxy resin reaction product and surfactant. In yet another aspect, the invention is a coating composition comprising an aqueous emulsion containing the hereinbefore describe epoxy resin coating composition, and a water-soluble dispersible, or emulsifiable curing agent or hardener for such epoxy resin composition.
