Abstract
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 bis-glycidyl 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.
