3M 421 Dark Silver Lead Foil Tape - 0.75 in. x 5 yds. Roll, Conformable Tape, Rubber Adhesive. Electrically and Thermally Conductive Tape [1 Roll]
3M 421 flexible lead foil tape with rubber adhesive is an electrically and thermally conductive tape for use in masking, shielding, sealing and decorative applications. Lead tape resists flame, moisture, weather, U.V. degradation, chemicals and performs over a wide variety of temperatures. Lead foil tape is acid resistant, ideal in the surface finishing industry for electroplating, anodizing and chemical milling masking applications. Plastic plating tapes often result in build-up at the stop-off line of the tape resulting in additional grinding; the lead foil backing can be burnished to fully cover the adhesive and allow full contact for uniform plating, the electrically conductive “thieving” action of lead foil tape eliminates metal plating edge build-up at the stop-off line creating an overall smooth surface. Lead foil tape offers good initial grab and a long-lasting bond that removes cleanly from most surfaces; use in the medical, aerospace, industrial and security industries as a radiation barrier for x-ray equipment; ideal for masking x-ray plates and sealing seams and joints between shielding panels in low energy x-ray applications. Lead foil tape works as a marker or locator for x-ray inspection operations. Very good conformability, use in the arts and crafts industry for decorative applications such as to simulate lead glass windows. Ideal weighting or balancing tape, works well to add weight to sports equipment parts such as golf clubs and tennis rackets.
