Withstands Exposure to High Heat and Humidity

3M™ Aluminum Foil Tape 427 is a reliable solution for heat dissipation and substrate protection in high temperature environments. Its dead soft, thermally conductive aluminum backing reduces hot spots and ensures that delicate parts are shielded from the effects of high temperatures. This tape is a linered version of 3M™ Aluminum Foil Tape 425, making it ideal for die cutting applications. Its highly engineered acrylic adhesive can withstand exposure to high heat and humidity while maintaining a strong and reliable bond. It can also withstand moisture, weathering, UV and solvents, making it suitable for indoor and 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
