Adhesive sheet strip

1. An adhesive sheet strip for a redetachable bond, removable from a joint by pulling in the direction of the bond plane, having a nonadhering grip tab and a subsequent single-sided or double-sided adhering strip, which comprises:

a) a backing composed of a film having a tensile strength of 2-20 N/cm and an elongation at break of 200-800%, and

b) applied to at least one side thereof polyurethane based adhesive comprising:

60-80% by weight of on aliphatic isocyanate/polyol crosslinking system.

15-35% by weight of a filler, and

0.05-0.20% by weight of an activator, based on the total weight of the adhesive.

2. The adhesive sheet strip as claimed in claim 1 , wherein the film is 40-80 μm thick.

3. The adhesive sheet strip of claim 2 wherein the film is made of a compound selected from the group consisting of polyethylene, polypropylene and polyurethane.

4. The adhesive sheet strip as claimed in claim 1 , wherein the adhesive is crosslinked thermally and, optionally, additionally by electron-beam curing, and optionally is additionally crosslinked at the cut edges, which are formed after the adhesive sheet strip has been cut, by UV or by further electron-beam curing.

5. The adhesive sheet strip as claimed in claim 1 , wherein the alphatic isocyanate/polyol crosslinking system comprises of: (1) an optionally modified hexamethylene diisocyanate as the aliphatic isocyanate component and (2) a polyetherpolyol and castor oil, which is optionally stabilized with tocopherols, as the polyol component.

6. The adhesive sheet strip as claimed in claim 1 , wherein the filler is selected from the group consisting of an absorbent, zinc oxide, calcium carbonate, magnesium carbonate and mixtures thereof.

7. The adhesive sheet strip as claimed in claim 1 , wherein the adhesive has been applied to both sides of the backing.

8. The adhesive sheet strip as claimed in claim 1 , wherein the adhesive is 10-80 μm thick.

9. The adhesive sheet strip as claimed in claim 1 , wherein the entire thickness of the adhesive sheet strip is 50-5000 μm.

10. The adhesive sheet strip as claimed in claim 1 , wherein the entire thickness of the adhesive sheet strip is 100-2000 μm.

11. A method of providing an adhesive bond to a surface which comprises applying the adhesive sheet strip of any one of claims 1-10 to said surface wherein parting of the adhesive bond, by pulling on said sheet strip in the direction of the bond plane, renders said surface damage-free and residueless.
