Industrial-grade aluminum foil tape with thermally conductive acrylic adhesive for heat shielding, chemical masking, and sealing applications. Temperature range -65°F to 300°F. UL certified for low flammability. 2 inches wide, 180 yards per roll, 6 rolls per case.
3M™ Aluminum Foil Tape 427 is a premium industrial-grade foil tape designed for demanding applications across aerospace, automotive, appliance, construction, electronics, and military industries. This linered version of the 3M™ Aluminum Foil Tape 425 features a dead soft aluminum foil backing with a highly engineered pressure-sensitive acrylic adhesive, making it ideal for heat shielding, heat reflecting, chemical masking, light enhancement, chemical milling, seaming, sealing, and de-paint operations. The tape's thermally conductive properties help dissipate heat and improve heating and cooling efficiency while protecting temperature-sensitive materials from thermal damage.
With a backing thickness of 2.8 mil and total tape thickness of 4.6 mil, this tape provides excellent durability and reliability in harsh industrial environments. The acrylic adhesive formulation is specifically engineered for long-term durability while maintaining the ability to remove cleanly after harsh masking applications. The tape withstands exposure to extreme temperatures ranging from -65°F to 300°F (-54°C to 149°C), as well as weathering, moisture, UV radiation, and various solvents, ensuring excellent work life both indoors and outdoors. Its chemical resistance makes it particularly valuable for de-paint processes and other chemical masking operations.
The product meets stringent safety and performance standards, including UL Recognition to UL 746C and UL Classification to UL 723 Class "L" for low flammability rating, and meets FAR 25.853(a) requirements. The dead soft aluminum foil backing conforms easily to curved and uneven surfaces, while the heat and light reflective properties enhance lighting efficiency and provide surface protection. Each case contains 6 rolls, with each roll measuring 2 inches wide by 180 yards long, providing 1,080 linear yards of tape per case for high-volume applications.
