Abstract
A sound damping material for use in a sound damping laminate having one or more rigid layers, such as those used in the automotive industry. The sound damping material is preferably a viscoelastic material that damps or otherwise inhibits the transmission of vibrational or acoustical energy through the laminate, and also acts as an adhesive for bonding the rigid layers together. In its cured form, the sound damping material layer can include an acrylate-based polymer matrix, and one or more of the following components: a precipitated phase, a viscous phase, and miscellaneous constituents. The acrylate-based polymer matrix is the reaction product of at least one acrylate-based monomer, such as isobornyl acrylate.
