摘要： A composition having sealing and sound dampening properties is disclosed which comprises one or more polyepoxides comprising at least two epoxide groups per molecule; a thermoplastic polyester polymer; a curing agent adapted to react with the polyepoxides; inorganic particles having an oil absorption value of less than 70; and inorganic microparticles different from the previously mentioned inorganic particles, the inorganic microparticles having an average particle size prior to incorporation into the composition ranging from 0.5 to 200 microns. Multilayer composites, coated substrates, and methods for forming sound dampening coatings on a metallic substrate are also provided.
