ABSTRACT:
Thermosetting coatings which cure to provide exceptionally corrosion resistant coatings are deposited at the cathode by combining a water dispersible salt of an acid with certain polyamine resins with a water dispersible heat-hardening phenolic resin. The polyamine resin is hydroxy functional and it contains diprimary amine adducted with the epoxy groups of an epoxy urethane. These polyamines provide aqueous electrocoating baths having a pH in the range of 5-7.5.
