ABSTRACT:
A heterogeneous two component waterborne urethane/vinyl polymer composition, the method of making the composition, and the coating derived therefrom. The composition is a low or zero VOC composition containing a polyol stabilized non-functional, high Tg, aqueous vinyl polymer latex, a water dispersible polyisocyanate, and, optionally, a polyhydric alcohol. The composition is formed by emulsion polymerizing one or more vinyl monomers which will form a high Tg polymer, in the presence of an emulsifier containing one or more acid-containing polyols which have been neutralized with one or more reactive amines, and combining the resulting polyol-stabilized high Tg aqueous vinyl polymer latex with a water-dispersible polyisocyanate and, optionally, a polyhydric alcohol.
