Product Description

3M Lead Foil Tape 420 Flame Retardant Moisture Resistant Electrically Conductive Tape

 

Product Description
 

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. Mated with an easy-release film liner, this 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 420 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 or as a radiation barrier. 

 

Features
 

• Very good conformability.

• Good thermal properties and will perform over a wide variety of temperature conditions (-60° to 225°F or -54° to 106°C). It has been used at higher temperatures for shorter duration.

• Electrically and thermally conductive.

• Can be die-cut into specific shapes.

• This material when disposed of separately is classified as RCRA hazardous waste. Please consult applicable Federal, State and local regulations for proper disposal.

• Elevated lead levels in water may result from long term submersion of this product.

• Best results are obtained when applied to a clean dry surface above 32°F (0°C). Also, by "feathering" the edges - 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.

Applications:

With the strong adhesive system of 3M 100MP, 3M 9460PC  Tape has very high adhesion of strength, which can replace the function of rivets, spot welds, liquid adhesives to a permanent bond. It's designed for used with medium and high surface energy materials like metals, polyimides and polycarbonate, it also performs well under high heat or cold and cyclic conditions. The long term operation temperature is 149ºC (300°F) and short term temperature resist to 260ºC(500°F) It can used to bond metal to metal , or bond polyimide to aluminum or bond metals decals to mufflers.

 

 

Application industry:

 

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