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.
