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

PRODUCT FAQ

  1. What is 3M™ Aluminum Foil Tape 425 used for?

    Great question! This tape is typically used for sealing and protecting joints and seams on aluminum-faced fiberglass insulation, as well as on sheet metal ducts.

  2. Is this tape easy to use?

    Yes indeed! The aggressive acrylic adhesive bonds quickly and securely to a variety of surfaces, and the backing conforms easily to irregular shapes or surfaces. Plus, it's designed to resist flame, moisture deterioration, UV exposure, chemicals solvents and outdoor weathering.

  3. How much of the tape comes in a case?

    each order contains 36 rolls per case so you can enjoy high quality product with enough stock that lasts for your project needs.

Withstands Exposure to High Heat and Humidity

3M™ Aluminum Foil Tape 425 is a reliable solution for heat dissipation and substrate protection in high-temperature environments. Its dead soft, thermally conductive aluminum backing reduces hot spots and its highly engineered acrylic adhesive maintains a strong bond even when exposed to high heat (up to 300°F/149°C) and humidity. It's used in the aviation and automotive industry, predominantly for paint stripping applications. This high-performance tape can withstand moisture, weathering, UV, and solvents, making it suitable for indoor and outdoor use.

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).
