The present invention provides an epoxy resin comprising: a polymer having a structure of a reaction product of a monomer of epoxy having at least two epoxide groups per molecule, a polyether monoamine, and an epoxidized oil. The present invention also provides an aqueous dispersion and a water-borne epoxy coating composition which comprise the epoxy resin. The present inventions are low in volatile organic compounds and have enhanced properties such as high hardness, high adhesion strength, high impact resistance and high corrosion resistance.

Epoxy resin, aqueous dispersion and water-borne epoxy coating composition comprising the same

This disclosure relates to reactive epoxy compounds that have high water solubility. The reactive epoxy compounds are obtained by mixing an epoxy resin having at least two epoxy groups per molecule with a carboxyl group-containing compound obtained by reacting a polyetheramine comprising a primary amine and an acid anhydride derived from a polyvalent carboxylic acid. This disclosure also relates to waterborne epoxy resin composition comprising core-shell type epoxy resin particles dispersed in a solvent, wherein the particles are formed by an epoxy resin encapsulated in the reactive epoxy compounds of the present invention. The waterborne epoxy resin composition is low in volatile organic compounds ('VOC').
