FLEXIBLE EPOXY SOUND DAMPING COATINGS

摘要

The invention is a sprayable coating having noise vibration and harshness reduction or absorption properties. Such composition comprises from 10 to 60 percent of the flexible epoxy resin, from 5 to 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 onto 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. The coatings of the invention provide for good noise and vibration properties, excellent corrosion resistance and abrasion resistance. The process of the invention allows for coating irregular shaped object in an easy manner.
