Withstands Exposure to High Heat and Humidity
Consisting of a dead soft, thermally conductive aluminum backing, 3M™ Aluminum Foil Tape 425 (PDF, 1.66 Mb) 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 (up to 300°F/149°C) 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.

Recommended Applications

  • Heat shielding of delicate parts
  • Heat reflecting
  • Masking in chemical paint stripping applications
  • Moisture barrier
  • Light reflecting for light enhancement
  • Chemical milling
  • Seaming and sealing
  • Refrigerator and freezer coil attachment
  • Splicing of thin gauge foils
  • Plastic protection


3M™ Aluminum Foil Tape 425 is UL Recognized to UL 746C (File E 122798) and Classified by UL to UL 723 "L" for low flammability rating (File R 7311). It can be certified to meet L-T-80C and meets F.A.R 25.853(a). Temperature use range is from -65° to 300°F (-54° to 149°C).

Customer Reviews
3M™ Aluminum Foil Tape 425 is rated 3.7 out of 5 by 3.
Rated 1 out of 5 by from The product adhesion is terrible I bought this tape 5 months ago but the quality of this product is terrible. It costed me 50USD. The adhesion of the product is not good at all. I was using 2 USD tape earlier which was showing better performance. I hope to get some sort of refund or a good alternate for the same.

Rated 5 out of 5 by from Everyday I'm Speed Taping Speed tape brings me daily joy. Is there some composite showing on a flap canoe? Time for speed tape. Is there a tray table broken? Time for speed tape! No time to fix it? Bring out the speed tape right now! Time to defer it.
