3M™ Aluminum Foil Tape 431 is a 2 mil dead-soft lightweight aluminum foil combined with our acrylic adhesive for excellent heat and light reflection to protect against high temperatures and U.V. degradation. The foil also serves as an excellent barrier against moisture, dust, flame, and certain chemicals.

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.

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
