Siliconized release film for the production of polymer moldings from fiber composites using a mold, which comprises a support film which is capable of vacuum deep drawing at room temperature and a coating which can be applied in liquid form and consists, optionally after removal of any solvent, of more than 90 atom % of silicon, carbon and/or oxygen, more than 45 atom % of carbon and more than 20 atom % of silicon, in each case based on the total coating and measured by XPS, characterized in that the coating has been crosslinked by means of condensation reactions, addition reactions or radiation.

A precursor composite material (60) is provided, having a layer sequence (50) comprising an adhesive layer (20), a carrier layer (10) on the adhesive layer (20), a release layer (40) on the carrier layer (10) and a parting layer (30) on the release layer (40), wherein the layer sequence (50) is arranged in such a way that the side of the adhesive layer (20) facing away from the layer sequence (50) is arranged at least in sub-regions on the side of the parting layer (30) facing away from the layer sequence (50). Further provided are a composite material, a method for producing the precursor composite material, a method for producing the composite material and a use of the precursor composite material and of the composite material.

A masking film includes an adhesion layer that includes at least one hydrogenated styrene block copolymer and an adhesive surface having a surface roughness (Sa) of greater than about 2.0 m. An Adhesion Build Value of the masking film is less than about 2.0 after the adhesion layer has been attached to a textured polycarbonate substrate and heated to 85 C. for 30 minutes.
