  • Patent number: 12577439
    Abstract: Disclosed are powerful adhesive tapes, which rapidly coat rough and/or curved surfaces with different surface energies and thereby build up high adhesion. The adhesive joints formed in this way furthermore have good shear strength, even at elevated temperatures. Finally, enduring mechanical loading on the adhesive joints does not lead to the adhesive tape peeling from the surface. This is achieved with an adhesive tape comprising at least one foamed layer and at least one adhesive compound layer, wherein the adhesive compound layer contains at least one poly(meth)acrylate, and the poly(meth)acrylate is cross-linked with at least one covalent and at least one coordinative cross-linker.
