Abstract: An epoxy resin composition comprising a blend of at least (i) at least one epoxy group containing a polycyclic group, and (ii) at least one epoxy group that is different from the epoxy resin in component (i). As exemplary of component (i) is an epoxidized tricyclo decanedimethanol. A renewable epoxy of component (ii) is cardanol epoxy, derived from cashew nut shell oil (CNSL). Optionally, a component (iii) which is any other epoxy from that of (i) and (ii) can be included, such as Bisphenol-A/F diglycidal ether. The blend is characterized by low viscosity, making it amenable to airless spray application, high solids content and excellent solvent resistance and abrasion resistance.

Abstract: 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.

Abstract: 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”).
