Abstract
A heat-activated sound and vibration damping sealant composition is provided. The composition includes dried automotive paint powder and an unsaturated polymer, where the paint powder reacts with the unsaturated polymer when the composition is heated to greater than 200° F. (80° C.). Upon heating, composition expands and increases in tensile strength. The composition may be provided in the form of a tape which is adhered to a substrate such as an automotive or appliance part and then exposed to elevated temperatures such as those encountered in automotive, appliance, or other commercial paint bake processes. Thereafter, the composition provides sound and vibration damping properties.
