A laminate is provided, more particularly an adhesive tape, comprising a) a release liner having at least one carrier layer (CL) and also, applied to this carrier layer (CL), at least one silicone coating (SC) of specific addition-crosslinked or radically crosslinked pressure-sensitive silicone adhesives, and b) at least one further layer (L1), comprising polyacrylate-based adhesives with low tack at room temperature or heat-activable bondable adhesives which have little or no pressure-sensitive adhesion at room temperature. The use of an arrangement as a release liner is also provided, where the arrangement comprises a carrier layer (CL) and also, applied to this carrier layer (CL), a silicone coating (SC) of specific addition-crosslinked or radically crosslinked pressure-sensitive silicone adhesives.

Adhesive tape with a poorly flowable pressure-sensitive adhesive and release liner based on a pressure-sensitive silicone coating

The invention relates to a method for producing a release liner which comprises at least one crosslinked silicon coating based on addition crosslinking silicone polysiloxanes and hydrosilylation catalysts, the silicon coating being treated with compounds that are effective as catalyst poisons for hydrosilylation catalysts. The invention further relates to a release liner which can be obtained according to said method and to the use of compounds that are effective as catalyst poisons for hydrosilylation catalysts for treating a silicon coating present on a release liner to control the release forces with which the release liner can be released from a pressure-sensitive adhesive composition that has been coated onto it.
