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 a 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.

3M™ Aluminum Foil Tape 431 is Classified by UL to UL 723 "L" for low flammability rating (File R 7311). It meets F.A.R 25.853(a). Temperature use range is from -65°; to 300°F (-54°; to 149°C).

Recommended Applications

Heat shielding of delicate parts Heat reflecting Moisture barrier Light reflecting for light enhancement Seaming and sealing Refrigerator and freezer coil attachment
