Abstract
Sprayable low-viscosity compositions have improved acoustic damping properties through the addition to the composition of a sterically hindered phenol, present in an amount from 9% to 18% by weight of the composition. In other embodiments, the sterically hindered phenol will have a melting point within the range from 60° C. to 250° C. and a molecular weight of 300 g/mol or less (but not 0).
