ABSTRACT:
Electrocoating compositions are provided in the form of aqueous dispersions of particulated polyimide. In addition, a method is also described for electrocoating metallic conductors, such as copper wire or aluminum strip. The particulated polyimide aqueous dispersions can be electrodeposited at significantly lower voltages than the corresponding polyamide acid salts.
