Abstract
Disclosed is a method for improving vibration damping of a substrate, such as the underbody of an automobile. The method comprises applying a plastisol which comprises a polymeric component, a general purpose plasticizer and a rosin ester resin. The fused plastisol has improved damping behavior as determined using Dynamic Mechanical Thermal Analysis.
