US Patent 11958995 Sealing adhesive tape for vehicle bodies

A method is provided for sealing discontinuities in vehicle bodywork, using an at least two-layer adhesive product which comprises at least one thermally activatable adhesive layer and a film layer of a polymeric material, where first the adhesive product is positioned with the adhesive layer onto the discontinuity for sealing, the adhesive layer sealingly wets the discontinuity, optionally after temperature increase, at elevated temperature the thermal activation of the adhesive ensues, characterized in that the adhesive layer used comprises a layer of a thermally activatable adhesive, specifically a layer based on a vulcanizable adhesive, and the thermal activation takes place with vulcanization of the adhesive.
