Abstract:
Adhesive tape for a bond which can be redetached by pulling without residue and without damage, having a foam backing coated on one or both sides with a self-adhesive composition, characterized in thata) on at least one of the two sides of the foam backing there is applied a self-adhesive composition whose ratio of tear strength to stripping force (peel force) at a peel angle of less than 10.degree. to the bond surface is greater than 1.2:1,b) the elongation at break of the adhesive tape is greater than the elongation at break of the foam backing, andc) the foam backing tears during the redetachment of the bond by pulling (stripping).
Abstract:
Use of a transparent grip tab for a strip of adhesive film for a temporary bond based on thermoplastic rubber and tackifier resins, where the adhesive film is of high elasticity and low plasticity and where the adhesion is lower than the cohesion, the adhesion largely disappears when the film is extended, the ratio of peel force to tear load is at least 1:1.5, and where an adhesive bond produced therewith can be detached by pulling on the adhesive film in the direction of the bond plane.
Abstract:
Redetachable, self-adhesive hook or similar fixing device, characterized by a strip (1) of an adhesive film for reseparable bonding based on a thermoplastic rubber and tackifying resins, wherein the adhesive film has high elasticity and low plasticity and wherein the adhesion is lower than the cohesion, the adhesive power largely disappears on extension of the film, the ratio of the peel strength to the tear load is at least 1:1.5, and wherein an adhesive bond produced with this can be separated by pulling on the adhesive film in the direction of the adhesion plane, wherein one end of the strip (1) is provided on both sides with a covering (4), which at the same time serves as a tab for pulling, wherein at least the covering (4) located on the front side is opaque to UV and wherein the front side of the strip (1) carries, except for in the region of the covering (4), a baseplate (3) having a peg-shaped extension (2) pointing forwards, and the reverse of the strip (1) is covered with a release paper or a release film (5) which has a tab (6) in the region of the covering (4).
