I would be really surprised if such an animal existed. Most tapes have an adhesive of some sort that nominally bonds with a surface. While your tape may volatilize, the adhesive probably will not Even then, when a material volatilizes, you have to ask yourself where it goes. It doesn't just disappear. Usually the smoke or othe decomposition products deposit on nearby surfaces. Never believe a salesman. Anyone who tells you you that it completely volatilizes and leaves no residue doesn't have a firm grasp of physics and little real world manufacturing experience.
