SPECIALTY TAPES

 3M 420 Lead Foil Tape is dark silver, 0.17 mm lead foil backing with rubber adhesive and a clear, easy-release film liner. A linered tape used as a maskant in electroplating and as a moisture and radiation barrier in certain applications.

Electrically conductive lead foil tapes minimize tape edge build-up during electroplating. The lead foil tapes' x-ray opacity characteristic helps protect and locate components during x-ray operations. Highly conformable, malleable, high density tapes with electrical conductivity, acid resistance and X-ray opacity.
