摘要:
Adhesive tape for a bond which can be redetached without residue or damage by pulling, having a backing coated on one or both sides with a self-adhesive composition, characterized in that a) a self-adhesive composition whose ratio of tear strength to stripping force (peel strength) at a peel angle of less than 10° to the bond surface is greater than 1.2:1 is applied to at least one of the two sides of the backing, b) the backing has been subjected to controlled pretreatment/damaging in such a way that the detachment force (stripping force) is lower than that of a similar self-adhesive tape with a backing which has not been so pretreated/damaged, and c) the tear strength of the backing is insufficient for redetachment without residue or damage.
