ABSTRACT:
The addition of blends of zinc borate and barium metaborate pigments to resinous film forming vehicles comprising blends of: (1) an aqueous acrylic latex with an alkyd resin, a styrene allyl alcohol ester adduct or a polymerized dehydrated castor oil product or (2) a solvent-based epoxy ester resin with a chlorinated paraffin; produce primer compositions in which corrosion resistance is synergistically enhanced. The resultant primer compositions may be used on ferrous or non-ferrous metallic substrates such as motor vehicles, appliances, aluminum lawn furniture, etc.
