Electrically and thermally conductive lead foil tape with rubber adhesive, flame and chemical resistant, ideal for electroplating masking and radiation shielding applications.
3M™ Lead Foil Tape 420 is an electrically and thermally conductive tape designed for industrial applications requiring superior performance in demanding environments. This highly conformable tape features a dark gray lead foil backing coated with a distinctive green rubber adhesive that provides excellent initial grab and long-lasting bond strength while removing cleanly from most surfaces. The tape resists flame, moisture, weather, UV degradation, and many chemicals used in electroplating and anodizing processes, making it ideal for specialized industrial masking and shielding applications.
The pliable and malleable construction of this lead foil tape allows it to be formed into detailed and intricate shapes and patterns, or die-cut into specific shapes to meet assembly and manufacturing process requirements. The lead foil backing can be burnished to fully cover the adhesive and allow full metal-to-metal contact with the base, resulting in a continuation of the electrical path and reducing build-up at the adhesive interface. With an easy-release film liner, this tape facilitates efficient application and handling in production environments.
With strong acid and base resistance, excellent electrical and thermal conductivity, and performance across a wide temperature range from -60°F to 225°F, this tape is formulated for use in aerospace, automotive, electronics, metalworking, and specialty vehicle manufacturing. Each case contains 36 rolls, providing ample supply for high-volume industrial operations requiring reliable masking, radiation barrier, moisture barrier, and chemical milling applications.
