Special electrolytic grade copper foil coated with a black pigmented acrylic pressure sensitive adhesive. The copper foil is a uniformly high tensile alloy with carefully controlled dead soft temper. This allows for tight conformation to cut edges and cast surfaces. Acrylic adhesive system resistant to high temperatures such as encountered in soldering. Presents a non reflective black, internal lip for near invisibility on the workpiece. Improves the aesthetics of copper foil on clear, non opalescent glass and mirrors. Thickness: 1.25 mils.
