3M Aluminum Foil Tape 425 is the go-to foil tape for numerous applications across a broad range of industries. 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

Withstands Exposure to High Heat and Humidity

3M™ Aluminum Foil Tape 425 is made up of a thermally conductive aluminum backing that is incredibly soft. This backing helps to dissipate heat over the surface of the tape, reducing hot spots and protecting the substrate from the effects of high temperatures. The tape is coated with a highly engineered acrylic adhesive that can withstand exposure to high heat (up to 300°F/149°C) and humidity while maintaining a strong and reliable bond. It can also withstand a variety of moisture, weathering, UV, and solvents, making it an excellent choice for indoor or outdoor use and especially in the aviation industry as it is used for masking sensitive components during aircraft paint stripping.

Recommended Applications
  • 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

3M™ Aluminum Foil Tape 425 is UL Recognized to UL 746C (File E 122798) and Classified by UL to UL 723 "L" for low flammability rating (File R 7311). It can be certified to meet L-T-80C and meets F.A.R 25.853(a). The temperature use range is from -65°F to 300°F (-54°C to 149°C).
