PRODUCT FAQ

  1. What is 3M™ Aluminum Foil Tape 439 used for?

    3M™ Aluminum Foil Tape 439 is typically used for sealing, patching and holding aluminum-backed duct boards and other HVAC components. It can also be used for general purpose functions such as masking, sealing, and non-reflective whiteboard writing.

  2. Can it withstand high temperatures?

    Yes! The foil backing on the tape can withstand temperatures ranging from -65°F/-54°C to 300°F/149°C without losing its performance.

  3. Does the adhesive hold up well in oily or greasy environments?

    Absolutely! Our cold temperature acrylic adhesive is specially designed to stick to a variety of surfaces including those that are oily or greasy.

  4. Is this tape easy to tear by hand?

    No worries there! The tape has been engineered with a zigzag pattern along the edges making it easy to tear by hand in both directions, lengthways and widthways.

  5. How much comes in each case?

    The pack includes twelve (12) rolls of the silver-colored aluminum foil tape each measuring 3.5 inches wide by

  6. 60 yards long, with a thickness of roughly three mils.

Withstands Exposure to High Heat and Humidity

3M™ Aluminum Foil Tape 439 is a thermally conductive tape that is designed to dissipate heat over the surface of the tape to reduce hot spots and protect the substrate from the effects of high temperatures. The tape is made up of a dead soft, thermally conductive aluminum backing and is a linered version of 3M™ Aluminum Foil Tape 431, making it suitable for die cutting applications. The tape is coated with a highly engineered acrylic adhesive that is capable of withstanding exposure to high heat and humidity while maintaining a strong and reliable bond. It can withstand a variety of moisture, weathering, UV, and solvents, making it an excellent choice for indoor or outdoor use.
