Abstract:
A pigment dispersing resin is disclosed along with pigment dispersion, electrodepositable coating compositions using the pigment dispersing resin, and methods for applying the electrodepositable coating composition. The pigment dispersing resin consists essentially of the carboxylic acid salt of an aminated bisphenol epoxy resin and an alkoxylated styrenated phenol. Pigment dispersions made from the dispersing resin are especially useful for forming low or no volatile organic content electrocoating baths.
