We developed 3M™ Lead Foil Tape 421 as an electrically and thermally conductive tape. This highly conformable tape resists flame, moisture, weather, UV degradation, chemicals and radiation. Mated with an easy-release film liner, our malleable tape can be shaped into complex or detailed patterns or die-cut into specific shapes to meet assembly and manufacturing process needs.

Pliable and Conductive Lead Tape Our dark silver, 6.3 mil /0.16 mm lead foil backing is coated with a distinct green rubber adhesive that offers good initial grab and a long-lasting bond. The lead in our 3M™ Lead Foil Tape 421 is a soft metal that offers excellent conformability. The lead foil is very pliable and can be shaped to the most detailed and intricate shapes or patterns. By rubbing the tape down with a smooth-edged plastic piece or similar object, the tape can be made to better conform to the substrate. This is especially important if the tape is to be used as a "thief" in electroplating, where the edges must fully contact the metal base. 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, as a radiation barrier or x-ray plate masking. Due to the density, weight and malleability of the lead foil, this tape makes an excellent choice for weighting and balancing, particularly for golf clubs where weight and conformability are crucial for balance and club performance. Application Ideas
3M™ Lead Foil Tape 421 can be used as a mask to eliminate the chemical impacts of electroplating, anodizing or chemical milling. It is also used for x-ray masking and radiopacity for x-ray makers. This versatile and reliable tape can also be used as a moisture barrier or for thermo pane window sealing. This heat and light reflective tape resists flame, moisture, weather, UV degradation, chemicals and is thermally conductive to enhance heating and cooling efficiency of electronics, windows and other applications where heat dissipation is desirable. The density of our lead tape also allows it to be used for precise weighting that requires adhering to low energy and other surfaces. Power your success with our exceptional science and engineering that provides long-lasting performance and successful solutions. |
