Viscoelastic adhesive tape made of butyl putty supported by high-density polyethylene films. Thanks to its great stretch capacity on both directions and given the high adhesive self-amalgamating power, it does not need a fixing primer. It perfectly impermeabilizes surfaces, insulating them from soft chemical and atmospheric agents. Excellent corrosion proofing covering for underground and overhead pipes (in this case protected by aluminium), sealing of metallic and cement surfaces in the building sector (joints, skylights, chimney flashings, cold flues, conditioning channels, etc.). Thanks to its great stretch capacity the tape has a quite universal adaptability to all surfaces, even to the most irregular ones (curves, Te, spigot joints, etc).

The surface has only to be clean and not humid. It has to be stripped exerting the necessary pulling stress according to the situation. Indeed, it can be stretched up to more than 700%. The final thickness changes according to the pulling stress exerted. An overlap of at least 10% of the tape width is recommended.
