Sound damping coating of flexible and rigid epoxy resins |
摘要 |
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.
