3M™ Aluminum Foil Tape 425 serves has excellent heat and light reflection to protect against high temperature and U.V. degradation. It's also an effective barrier against moisture, dust, flame, dirt and mild chemicals used in paint stripping and masking. The thermally conductive backing helps maximize efficiency by dissipating heat over a wider surface area. The synthetic acrylic adhesive provides superior temperature, U.V. and solvent resistance to produce a strong, lasting and reliable bond. It provides excellent age life and is ideal for harsh, long-term indoor and outdoor environments.

Recommended Applications

  • Aircraft paint stripping maskant
  • Moisture barrier in “white goods” appliances
  • General purpose heat reflector and heat dissipater
  • Mechanically hold wires and cooling coils in “white goods” appliances
  • Repair tears on truck trailers and aircraft
  • Splicing of thin gauge foils
  • General purpose holding, patching, sealing applications – indoors and out
  • Designed to seal the cut edges of 3M™ Interam Mats and 3M™ Duct Wrap to complete total encapsulation
  • Aluminum is just one of the metal-backed tapes available from 3M. Our line of foil tapes resist failure from many common sources of degradation, including moisture, ultraviolet rays and many chemicals. As with all 3M products, our Aluminum Foil Tape 425 comes with exclusive 3M technical expertise and application advice.
