Abstract
An adhesive tape (), in particular a double-sided adhesive tape has a substrate made of plastic with a self-adhesive, pressure-sensitive layer () consisting of a pressure-sensitive adhesive containing a UV-crosslinkable acrylate as primary constituent. In order to achieve an at least moderate, preferably increased adhesive force on nonpolar surfaces () as well as preferably an increased shear strength, while preserving the advantages of the use of UV-crosslinkable acrylates in the adhesive coating and ensuring an at least moderate, preferably increased adhesive force on steel, the pressure-sensitive adhesive contains powdered silicon dioxide, wherein the substrate () made of plastic is configured as a film. The pressure-sensitive adhesive is modified with tackifying resins, such as pinene, indene and/or colophonium resins, their disproportioned, hydrated, polymerized, esterified derivates and/or salts and/or terpene and/or terpene phenol resins and/or aliphatic, aromatic, alkyl aromatic hydrocarbon resins, and/or with one or several C5- to C9-hydrocarbon resin(s).
