Abstract

Water soluble epoxy‐amine adducts were prepared by reacting epoxy resin with diethanolamine in different molar ratios. These adducts were further partially esterified with linseed oil fatty acids. Aqueous coating compositions for cathodic electrodeposition were prepared from epoxy‐amine adducts and esterified epoxy‐amine adducts separately. Film properties of cathodically electrodeposited coatings were evaluated and studied. It was observed that coatings based on 20% and 30% esterified epoxy‐amine adducts had good overall film properties.
