Abstract

Hot-pumpable, heat-curing compositions based on solid ethylene/vinyl acetate copolymers and liquid reactive plasticizers containing olefinically unsaturated double bonds and at least one peroxidic crosslinking agent are suitable as sealing compounds for sealing fine and rough seams in vehicle manufacture. By adding expanding agents, the compositions may be used as lining adhesives. The preferred applications are at the white-shell stage of car manufacture.
