ABSTRACT:
Thermally stable hot applied plastisol compositions are especially useful in the assembly of metal parts. The compositions have adhesive and sealant qualities which allow them to be used in automotive assembly plants. Compositions of the invention comprise as major ingredients finely divided polyvinyl chloride resin, plasticizer, thermoplastic polymeric resin which is solid at room temperature but softens to a flowable state at application temperature, and an adhesion promotion system. Optionally a filler, wax, heat stabilizer, pigment, wetting agent, or mixtures thereof may be added. The individual components work synergistically to get good application properties, metal adhesion, wash-out resistance, and paintability.
