Abstract

Thermally vulcanisable, meltable adhesives and processes have a meltable polybutadiene-polyurethane, ground sulphur and optionally at least one vulcanisation accelerator, at least one filling material, at least one epoxide resin, at least one tackifier resin, bitumen, at least one softener and further auxiliary and additive materials, wherein said adhesives and processes can be thermally vulcanised within a temperature range of 130° C. to 230° C., such that same, as well as an adhesive strip produced from same, can be used for adhesion and/or sealing in the automotive industry, as well as in structural work on oiled sheet metal, and in the painting line on e-coated or otherwise painted sheet metal, for example, for crimp fold adhesion, for crimp fold sealing, for seam sealing, for lining adhesion, for hole closure and much more.
