Withstands Exposure to High Heat and Humidity

3M™ Aluminum Foil Tape 427 is made up of a thermally conductive aluminum backing that is dead soft. This backing helps to dissipate heat over the surface of the tape, reducing hot spots and protecting the substrate from the effects of high temperatures. This tape is a linered version of 3M™ Aluminum Foil Tape 425, which makes it suitable for die cutting applications. It is coated with a highly engineered acrylic adhesive that can withstand 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, making it an excellent choice for indoor or outdoor use.

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 427 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). The temperature use range for this tape is from -65°F to 300°F (-54°C to 149°C).
