Abstract
In one aspect, the present disclosure relates generally to a set acoustic adhesive composition having a storage modulus at 20° C. of at least 2.0 MPa over a frequency of 1-10 kHz, the set acoustic adhesive composition comprising: a continuous phase of a viscoelastic material present in an amount in the range of 60-95 wt % of the set adhesive composition; and dispersed in the continuous phase, a particulate polymer filler present in an amount in the range of 5-40 wt % of the set adhesive composition, wherein the particulate polymer filler has a storage modulus at 20° C. of at least 50 times a storage modulus at 20° C. of the continuous phase at 20° C., over a frequency of 1-10 kHz; and/or the viscoelastic material of the continuous phase has a glass transition temperature (T) no greater than 0° C., and the particulate polymer filler has a glass transition temperature (T) of at least 60° C.
