ABSTRACT:
Disclosed is a liquid coating composition, useful for making a chip resistant coating, comprising a binder of: a first and a second urethane resin each containing terminal, reactive ethylenically unsaturated groups. Each urethane resin is prepared by reacting components comprising (A) an isocyanate-terminated prepolymer which is the product of reacting an organic polyisocyanate with an organic polyol with (B) an isocyanate reactive group-containing unsaturated monomer selected from hydroxyalkyl acrylates, hydroxyalkyl methacrylates and hydroxyalkyl acrylamides. The organic polyol for the first urethane resin has a hydroxyl functionality of 3 or more; the organic polyol for the second urethane resin has a hydroxyl functionality of less than three; and the average functionality of the polyols utilized for the first and second urethane resins is less than three.
Also disclosed is a method of making a cured chip resistant, coating.
