These highly conformable tapes are designed for many applications requiring moisture and chemical resistance, thermal conductivity, heat and light reflectance, flame resistance, and weatherbility.
3M Metal Foil Tape 425, highly reflective acrylic backing provides excellent radiation of both heat and light. 3M Metal Foil Tape 425 is our most versatile aluminum tape. Long aging, both indoors and out. Use as a mask in electroplating and paint stripping operations, where it reduces edge build-up. 3M Metal Foil Tape 425 is also good for general sealing, metal patching, moisture barrier and heat-reflecting.
420 TAPE3M Lead Foil Tape 420, linered tape used as a maskant in electroplating and as a moisture and radiation barrier in certain applications. Lead foil backing provides good conformability having electrically and thermally conductive properties. This linered tape can be easily die-cut into special sizes or shapes.
