Flexible aryl alkyl epoxy resins, their amine resin derivatives and their use in electrodeposition coatings

Abstract From the Canadian patent

Abstract of the Invention, A series of oligomeric adducts of diols and diepoxides are disclosed which are precursors of amine resins for use in electrodeposition coatings. The adducts are epoxide-alcohol addition products of a polyaromatic and/or a mono-aromatic diol and a polyaromatic bisglycidyl ether, and/or a monoaromatic bis-glycidyl ether and/or an alkoxy arylene bis-glycidyl ether thioether, or amine. The coatings which include amine resin cross, linking agent, grind resin and pigment exhibit excellent corrosion resistance.
