Abstract (en)
[origin: WO2019145194A1] The present invention relates to a layer composite, in particular an adhesive tape, which comprises a) a release liner composed of a carrier layer and a non-tacky silicone coating of special addition-crosslinked or radically crosslinked silicone pressure-sensitive adhesives, and b) at least one layer of polyacrylate-based adhesives which are only slightly tacky at room temperature or adhesives which can be adhered under the action of heat and are not or only little pressure-sensitive at room temperature. The present invention further relates to the use of an arrangement as a release liner which contains a carrier layer and the previously stated silicone coating of special addition-crosslinked or radically crosslinked silicone pressure-sensitive adhesives.
