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

Plastic protection against heat and UV exposure


  • Thermally conductive tape helps dissipate heat and improves heating and cooling efficiency to protect temperature sensitive materials
  • Highly engineered acrylic adhesive provides long term durability, but removes cleanly after harsh masking applications
  • Dead soft aluminum foil backing conforms to curved and uneven surfaces
  • Withstands exposure to flame, weathering, moisture and UV
  • Heat and light reflective tape protects surfaces and enhances lighting efficiency
  • Classified by UL to UL 723, Class "L" for low flammability rating
