Abstract

A quaternary ammonium group-containing material which is obtained from reacting a polyepoxide with an amine containing at least one acyclic group of about 8 to 30 carbon atoms and optionally an amine containing an alkylarylpoly ether moiety is disclosed. The resins are useful as pigment grinding vehicles and in the formulation of pigment paste, particularly pigment paste with high pigment loadings. When formulated into cationic electrodepositable compositions, the pigment grinding vehicles provide for cured electrodeposited coatings of excellent corrosion resistance, particularly over untreated and oily steel.
