Abstract

Use of a prior-cleaning cloth for an adhesive bond brought about by means of an adhesive film which is rereleasable without damage by pulling in the direction of the bond plane and which has an adhesive composition based on polymers and/or copolymers of synthetic rubber and/or natural rubber, characterized in that the substrate to be bonded is rubbed with a prior-cleaning cloth of this kind which is impregnated with a moisture-reactive organosilane, the organosilane being dissolved in a solvent or solvent mixture and being present therein in a concentration of 0.1-3% by weight, whereupon, following a waiting time of a few minutes, the adhesive film is pressed onto the treated area and then an article, hook or the like is bonded to the other side of the adhesive film, or else in that, after a waiting time of a few minutes, the adhesive film is pressed onto the treated area, an article, hook or the like already being located in bonded-on form on the reverse of the adhesive film.
