Abstract
An adhesive tape for bonding low-energy surfaces, comprising a UV cross-linked pressure-sensitive adhesive compound which comprises poly-acrylate, a linear or branched vinyl aromatic block co-polymer and at least one adhesive resin. The UV cross-linking of the pressure-sensitive adhesive compound is the result of irradiation with UV-A-containing light.
Claims19
An adhesive tape for bonding low-energy surfaces, comprising
- a UV-cross-linked pressure-sensitive adhesive compound, comprising poly-acrylate,
- a linear or branched vinyl aromatic block co-polymer, and
- at least one adhesive resin,
- wherein the UV cross-linked pressure-sensitive adhesive compound adaped to be cross-linked as a result of irradiation with UV-A-containing light.
1 more element
A method for producing an adhesive tape for bonding low-energy surfaces, the method comprising:
- a) melting of a vinyl aromatic block co-polymer and an adhesive resin;
- b) stirring the vinyl aromatic block co-polymer and the adhesive resin;
- c) adding a UV cross-linkable pressure-sensitive adhesive compound for producing a blend;
- d) applying the generated blend of vinyl aromatic block co-polymer, adhesive resin and pressure-sensitive adhesive compound on a sheet material;
- and
- e) irradiating the blend with UV-A-containing light to provide a UV cross-linked adhesive tape.
