Abstract
A waterborne sound and vibration damping composition including a waterborne emulsion polymer, the polymer having a calculated acid number of from 2 to 100; from 0.1% to 50%, solids based on emulsion polymer solids, of certain liquid compounds having a boiling point greater than 150° C.; and a solid filler at a level of from 25% to 85% PVC; wherein the waterborne damping composition has a water content of from 6% to 25% by weight is provided. A method for providing a coated substrate using the waterborne damping composition and a substrate so coated are also provided.
