ABSTRACT:
Electrodepositable resins that do not require chromate corrosion inhibiting pigments and comprise (A) the at least partially neutralized reaction product of (1) an epoxy reactant having about two or more epoxy groups that are not linked by carboxy-ester moieties and (2) an amine reactant selected from mono and diamines containing primary or secondary amino groups and also being at least about 50 mole percent hydroxy amine, (B) water soluble or dispersible amino resin crosslinking agent are improved by incorporation of (C) a co-reactive flow control agent that comprises, for example, a polyepoxy copolymer having a molecular weight desirably between 1000-20,000. The co-reactive flow control agent, used at low levels, allows formation of smooth, non-tacky films exhibiting desirable corrosion resistant properties.
