Pliable and Conductive Lead Tape
3M™ Lead Foil Tape 420 is a dark gray, lead foil backed tape coated with a distinct green rubber adhesive that offers good initial grab and a long-lasting bond that removes cleanly from most surfaces. It is an extremely conformable and pliable tape that can be formed into detailed and intricate shapes and patterns. The lead foil backing can be burnished to fully cover the adhesive and allow full contact of the lead foil to the metal base. This metal to metal contact results in a continuation of the electrical path, reducing build-up at the adhesive interface. This lead foil tape is formulated to be electrically and thermally conductive and carries a strong acid and base resistance, making it ideal for electroplating or as a radiation barrier.
