3M™ Aluminum Tape 425 is the go-to foil tape for numerous applications. Comprised of a dead soft aluminum foil backing and coated with a highly engineered pressure sensitive acrylic adhesive, it is ideal for heat shielding, heat reflecting, chemical masking, light enhancement, chemical milling, seaming, sealing and de-paint operations.



  • Thermally conductive tape helps dissipate heat and improves heating and cooling efficiency to protect temperature sensitive materials
  • Resistant to chemicals to protect surfaces during de-paint process and other chemical masking operations
  • Highly engineered acrylic adhesive provides long term durability, but removes cleanly after harsh masking applications
  • Withstands exposure to flame, weathering, moisture and UV
  • Heat and light reflective tape protects surfaces and enhances lighting efficiency
  • Dead soft aluminum foil backing conforms to curved and uneven surfaces


  • Heat shielding of delicate parts
  • Heat reflecting
  • Masking in chemical paint stripping applications Moisture barrier
  • Light reflecting for light enhancement
  • Chemical milling
  • Seaming and sealing
  • Refrigerator and freezer coil attachment
  • Splicing of thin gauge foils
  • Plastic protection
