Product Overview
The 3M™ Lead Foil Tape 420 is an electrically and thermally conductive tape. This highly conformable tape resists flame, moisture, weather, UV degradation, chemicals, and radiation. Combined 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.The 3M Lead Foil Tape 420 is a dark silver, lead foil backed tape coated with a distinct green rubber adhesive that offers good initial grab and a long-lasting bond that removes cleanly for 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. Lead foil tape is often used on golf clubs to control weight distribution.
