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).

Adhesive tape, in particular, double-sided adhesive tape, and use thereof for attaching to non-polar surfaces

An acrylate copolymer for use in pressure-sensitive adhesives, particularly suitable for the bonding of low-energy surfaces, is composed of the following monomer components: A) 60 to 95% by weight of one or more monomers selected from alkyl acrylates and alkyl methacrylates, the alkyl containing 1 to 10 carbon atoms; B) 5 to 15% by weight of one or more monomers selected from esters of (meth)acrylic acid with a polyethylene glycol derivative having from 2 to 4 ethylene glycol units, the (meth)acrylic esters being free from hydroxyl groups; and C) 1 to 35% by weight of a mixture of at least two vinyl compounds selected from vinyl compounds which contain one or more of the following functional groups: free carbonyl groups, free carboxyl groups, groups having one or more active hydrogen atoms.
