Abstract
Pumpable thermally foaming filler compositions based on combinations of a liquid epoxy resin and a polyvinyl chloride resin and/or an acrylic resin powder. The pumpable filler materials provide the advantage that they can be applied as needed using conventional injection equipment and can be expanded to provide foam with good physical strength, high expansion and excellent adhesion on oiled metal substrates. Methods for filling closed spaces with the pumpable thermally foaming filler composition as well as vehicle parts are obtainable with the indicated methods.
