PRODUCT FAQ
-
What is the 3M™ Aluminum Foil Tape 439 used for?
The 3M™ Aluminum Foil Tape 439 is specifically designed for applications that require a moisture, chemical, or thermal resistant barrier such as sealing seams in aluminum-faced foam insulation.
-
How much tape comes in each case of the product and what are its dimensions?
Each case of this product contains four rolls of tape. The dimension of each roll is 6 inches x 60 yards with a thickness (also known as Mil) rating of approximately 3.1 mil.
-
Is it easy to use and apply the product?
Yes! It has pressure-sensitive acrylic adhesive that ensures excellent adhesion so you can easily seal metal joints and seams even at low temperatures.
-
Is it safe for industrial/commercial use?
Absolutely! This harnesses the strength and durability attributes required for demanding industrial processes making them trustworthy tapes guaranteed to adhere under moist conditions common in HVAC systems.
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.
