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
-
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.
-
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.
-
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.
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.
