The copper foil is a special electrolytic grade copper foil, uniformly high tensile alloy with carefully controlled dead soft temper. This allows for tight conformation to cut edges and cast surfaces. The acrylic adhesive system is resistant to high temperatures such as those encountered in soldering. The black-backed option is developed for use on clear glass and mirrors. When the finished project is coated with black patina, the adhesive side is not evident as it would be with regular foil.
