Procedure

A zinc acrylate polymer was prepared by the reaction of zinc oxide and naphthenic acid (acid value 200 mgKOH/g) with a carboxylic acid functional acrylic copolymer based on the monomers; Acrylic acid (18.4 mol %), ethyl acrylate (80.35 mol %) and, methoxy polyethyleneglycol methacrylate (MPEG350) (1.25 mol %). These components were mixed at a 1:1:1 molar ratio (Zinc oxide:Naphthenic acid:polymer carboxylic acid groups) in xylene/n-butanol (4:1 weight ratio) and heated and stirred at 95° C. until a clear solution was obtained resulting in a solution of zinc acrylate polymer of 45 wt % in xylene/n-butanol/water (43.3:10.8:0.9 wt %).
