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.

Pliable and Conductive Lead Tape
3M™ Lead Foil Tape 421 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, as a radiation barrier or x-ray plate masking.

Application Ideas


Electroplating
Radiation barrier
Moisture barrier
Chemical milling
X-ray plate masking

3M 421 Features:
  • 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
3M 421 Specifications:
  • Color: Dark Silver
  • Package Quantity: 36 RLS
  • Width: 0.25 in
