Claim 0:
1. A method for sealing discontinuities in vehicle bodywork, comprising:
providing an at least two-layered adhesive product which comprises at least one thermally activatable adhesive layer and a film layer of a polymeric material;
positioning the adhesive layer of the adhesive product onto a discontinuity, wherein the adhesive layer sealingly wets the discontinuity; and
thermally activating the adhesive layer at an elevated temperature,
wherein the adhesive layer comprises a vulcanizable adhesive,
wherein a vulcanization of the adhesive layer occurs during the step of thermally activating the adhesive layer,
wherein the vulcanizable adhesive comprises a polybutadiene-polyurethane and a sulfur-containing vulcanizing agent, and
further wherein the vulcanization takes place in the presence of at least one vulcanizing agent comprising one or more of sulfur, a sulfur-containing compound, a peroxide and a metal oxide.
