Withstands Exposure to High Heat and Humidity
Consisting of a dead soft, thermally conductive aluminum backing, 3M Aluminum Foil Tape 431 dissipates heat over the surface of the tape to reduce hot spots and protect the substrate from the effects of high temperatures. Coated with our highly engineered acrylic adhesive, it is capable of withstanding exposure to high heat and humidity while maintaining a strong and reliable bond. This tape can withstand a variety of moisture, weathering, UV and solvents in order to provide an excellent work life, indoors or out.
