3M Lead Foil Tape 421 Is an electrically and thermally conductive tape. This highly conformable tape resists flame, moisture, weather, UV degradation, chemicals and radiation. The malleable tape can be shaped into complex or detailed patterns or die-cut into specific shapes to meet assembly and manufacturing process needs.
- Conformable tape resists flame, moisture, weather, UV degradation, and many chemicals
- Performs over a wide variety of temperature conditions and is heat reflective
- Heat and light reflective tape protects, insulates and enhances lighting efficiency
- Can be die-cut into specific shapes for assembly and manufacturing processes
- The rubber-based adhesive combined with the rugged, durable backing provides long service life

PRODUCT FAQ
-
What is the lead content of 3M™ Lead Foil Tape 421?
The lead content in this tape is below trace levels to meet industry standards.
-
Can I use it for outdoor applications?
Yes, you can use the 3M™ Lead Foil Tape 421 outdoors as it has weather-resistant properties that keep its adhesive intact.
-
How strong is the adhesive on this tape?
The aggressive acrylic adhesive layer offers immediate adhesion and long-term holding power on surfaces both indoors and outdoors.
This 3M™ Lead Foil Tape 421 is a pliable and conductive tape that is perfect for a variety of applications. The tape has a dark silver, 6.3 mil /0.16 mm lead foil backing that is coated with a distinct green rubber adhesive. This adhesive offers good initial grab and a long-lasting bond. The lead foil is a soft metal that offers excellent conformability, making it easy to shape 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- Electroplating
- Radiation barrier
- Moisture barrier
- Chemical milling
- X-ray plate masking
- Add weight and balance to equipment parts, golf clubs, tennis rackets, etc.
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 the lead tape also allows it to be used for precise weighting that requires adhering to low energy and other surfaces.
