ABSTRACT:
A binder system is provided which is suitable for use as a waterborne coating, particularly as a topcoat over hydro-basecoats. The binder in accordance with the present invention comprises a water-soluble acrylic resin which has been modified using a monoisocyanate functional compound. The waterborne coating comprises this binder system in an aqueous base. The resulting waterborne coating exhibits high gloss, high solids content with low cosolvent content, good application characteristics, and good stone-chip and weathering resistance. The present waterborne coating also finds use, for example, as an electrocoat, primer/surfacer and/or solid color topcoat.
