Premium industrial aluminum foil tape with thermally conductive acrylic adhesive, designed for heat shielding, chemical masking, and high-temperature applications up to 300°F. UL certified for low flammability with superior chemical and UV resistance.
3M™ Aluminum Foil Tape 425 is a premium industrial-grade foil tape engineered for demanding applications across aerospace, automotive, appliance, and construction industries. Comprised of dead soft aluminum foil backing with a highly engineered pressure-sensitive acrylic adhesive, this tape delivers exceptional thermal conductivity and chemical resistance. The tape measures 6 inches wide by 60 yards long with a total thickness of 4.6 mil, featuring a 2.8 mil backing thickness and 1.8 mil adhesive thickness.
Designed to withstand extreme conditions, this thermally conductive tape helps dissipate heat and improves heating and cooling efficiency while protecting temperature-sensitive materials. It maintains a strong, reliable bond while withstanding exposure to high heat up to 300°F (149°C), humidity, moisture, weathering, UV rays, and various solvents. The tape is resistant to chemicals, making it ideal for de-paint processes and other chemical masking operations. Its dead soft aluminum foil backing conforms seamlessly to curved and uneven surfaces, ensuring complete coverage and superior adhesion.
This professional-grade tape 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 meets F.A.R 25.853(a) specifications and operates reliably across a temperature range from -65°F to 300°F (-54°C to 149°C). Each case contains 2 rolls, providing 120 yards of total coverage for maximum value and convenience in industrial applications.
