The invention is a sprayable coating having noise vibration and harshness reduction or absorption properties. Such composition comprises from about 10 to about 60 percent of the flexible epoxy resin, from about 5 to about 40 percent by weight of a rigid epoxy resin formulation, and a curing agent for the epoxy moieties of the two resins. In another embodiment, the invention is a method of coating a substrate to reduce the impact of noise vibration and harshness on the substrate or users of the substrate, which process comprises spraying the above defined composition on to a substrate and curing the resin on such substrate. In yet another embodiment the invention is a coated substrate described herein before having enhanced noise vibration and harshness properties.

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.
