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.
