ABSTRACT:
A formulation for covering vehicle panels, such as the inner fenders or floor boards of an automobile, with a chip resistant, vibration damping coating. The formulation includes a blocked polyurethane prepolymer (or a blocked polyisocyanate and a polyol), an epoxy resin, a filler and a plasticizer. A method for forming a chip resistant, vibration damping coating on such a panel including the steps of applying a coating mixture to the panel, the coating mixture including a blocked polyurethane prepolymer (or a blocked polyisocyanate and a polyol) and an epoxy resin, and then heating the panel to form the coating. An improved vehicle panel, wherein the improvement is a polyurethane modified epoxy coating (or a coating which is an interpenetrating network of polyurethane resin and epoxy resin) on the panel.
