REACTIVE EPOXY COMPOUNDS AND METHOD FOR PRODUCING THE SAME, CORE-SHELL TYPE EPOXY RESIN PARTICLES, WATERBORNE EPOXY RESIN COMPOSITION, AND COATING COMPOSITION CONTAINING THE REACTIVE EPOXY COMPOUNDS

摘要

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”).
