ACOUSTIC DAMPING COMPOSITION HAVING ELASTOMERIC PARTICULATE

摘要

An acoustic damping composition includes a urethane component, elastomeric particles, and a binder resin including an addition polymer having a carboxylic functional group. The acoustic damping composition can have a Mode 1 Damping Parameter of at least 0.45. The binder resin can have a glass transition temperature of not greater than −25° C.
