Coating compositions, coatings and methods for sound and vibration damping and water resistance

Abstract

A coating composition having a measured solids content of at least 95% according to test method ASTM D2369 is disclosed. The composition includes a mixture of (a) a polymer prepared from one or more functional monomers comprising a (meth)acrylic monomer, an allyl monomer, or combinations thereof each having an ethylenically unsaturated double bond and an additional reactive functional group, and (b) a reactive diluent. At least some of the additional reactive functional group of the functional monomer remains unreacted during formation of the polymer. The reactive diluent has a boiling point of greater than 100° C. and a reactive functional group that reacts with the reactive functional group on the polymer at a temperature that is lower than the boiling point of the reactive diluent. Also disclosed are substrates having a cured coating thereon, the coating formed from the cured coating composition, and methods for providing sound and vibration damping.
