A coating composition particularly suitable for coating poly(phenylene oxide) comprises aqueous medium-dispersed particles of: A) between about 30 and about 35 wt %, of a first styrene-acrylic polymer formed of monomers, between about 50 and about 80 mole % of which monomers are styrene or substituted styrene monomers, between about 2 and about 15 mole percent of which monomers are acrylonitrile, and between about 18 and about 48 mole percent of which are acrylic monomers, said first styrene-acrylic polymer having an acid number of about 15 or below; B) between about 30 and 35 wt %, of an acrylic second polymer formed of monomers, at least about 90 mole percent of which monomers are acrylate monomers, balance other &agr;, &bgr;-ethylenically unsaturated monomers, said acrylic second polymer having an acid number between 0 and about 25; and C) between about 30 and about 40 wt % of an acrylic-urethane hybrid polymer.

One component waterborne coating with improved chemical resistance

A one-coat, waterborne coating system for a polypropylene substrate comprises a mixture of an an acid functional acrylic resin latex, a latex of chlorinated polyolefin resin, and a cross-linking agent reactive with the acid functionality of the acrylic resin.
