Abstract:
A method and composition for damping vibration of a substrate as well as a construction configured to achieve dampened vibration transmission. The construction includes a substrate configured to transmit NVH associated vibration in at least one frequency range. The construction also includes a first polymeric layer overlying at least a portion of the substrate element. The first polymeric layer comprises at least one material having elastomeric characteristics in a Tg range between +10 to −10° C. as outlined in ASTM E1640-00 and a hardness of between 5 and 25 as measured with the Shore A methodology outlined in ASTM D2240-00 and a second polymeric layer having elastomeric characteristics less than those exhibited by the first layer.
