COATING COMPOSITIONS, COATINGS AND METHODS FOR SOUND AND VIBRATION DAMPING AND WATER RESISTANCE

摘要

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 having 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 at least one ethylenically unsaturated functional group, no additional functionality, and a boiling point of greater than 100° C. The ethylenically unsaturated functional group of the reactive diluent and the additional reactive functional group remaining within the polymer do not react. Also disclosed are coatings formed from the cured coating composition and methods for providing sound and vibration damping through a substrate.

1. A coating composition comprising:
a mixture comprising: (a) a polymer prepared from 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, wherein at least some of the additional reactive functional group of the functional monomer remain unreacted during formation of the polymer; and (b) a reactive diluent having at least one ethylenically unsaturated double bond, no additional functionality, and a boiling point of greater than 100° C.; and a filler material; wherein the ethylenically unsaturated functional group of the reactive diluent and the additional reactive functional group remaining within the polymer do not react; and wherein the coating composition has a measured solids content of at least 95% according to test method ASTM D2369.
