ABSTRACT:
A preferably unbacked adhesive tape with permanent full-area pressure sensitive adhesion, composed of a film of a pressure sensitive adhesive which is preferably coated onto an antiadhesive medium and comprisesan alkaline, solid, pulverized, mineral filler with a weight fraction of between more than 5% by weight and 60% by weight, based on the total weight of the adhesive, so that the permanently pressure sensitively adhesive surface of the adhesive tape has a pH of more than 8, anda conductive additive, especially a metal powder, a powder coated with a metal, and/or metallized beads, with a weight fraction of between more than 5% by weight and 60% by weight, so that the adhesive tape is electrically conductive in the z direction, i.e., in the direction of the thickness of the tape.
