More Information
Summary:An aqueous polymer dispersion containing a water-dispersible polyurethane and a vinyl polymer, the polyurethane being the product of reacting an active hydrogen containing chain extender with a water-dispersible isocyanate-terminated polyurethane prepolymer derived from a polyisocyanate component containing at least 5% by weight of 2,4 min -diphenylmethane diisocyanate. The dispersions are useful as coating compositions.
