Premium thermally conductive aluminum foil tape with acrylic adhesive for heat shielding, chemical masking, and industrial sealing applications. UL recognized, temperature range -65°F to 300°F, 12 in x 60 yd roll.
3M™ Aluminum Foil Tape 427 is a premium industrial-grade foil tape engineered for demanding applications requiring superior thermal conductivity and chemical resistance. This versatile tape features a dead soft aluminum foil backing with a highly engineered acrylic adhesive, making it ideal for heat shielding, heat reflecting, chemical masking, light enhancement, chemical milling, seaming, sealing and de-paint operations. The linered version design makes it particularly suitable for die cutting applications, offering exceptional performance across aerospace, automotive, appliance, construction, electronics, and general industrial sectors.
The tape excels at dissipating heat over its surface to reduce hot spots and protect substrates from high temperature effects while maintaining a strong, reliable bond even under exposure to high heat and humidity. With a temperature use range from -65°F to 300°F (-54°C to 149°C), it withstands exposure to flame, weathering, moisture, UV radiation, and various solvents, providing excellent work life both indoors and outdoors. The dead soft aluminum backing conforms easily to curved and uneven surfaces, while the pressure-sensitive acrylic adhesive removes cleanly after harsh masking applications without leaving residue.
UL Recognized to UL 746C (File E 122798) and Classified by UL to UL 723 Class "L" for low flammability rating (File R 7311), this tape meets FAR 25.853(a) specifications and can be certified to L-T-80C standards. Each roll measures 12 inches wide by 60 yards long with a total thickness of 4.6 mil, backed by 2.8 mil aluminum foil and 1.8 mil acrylic adhesive, featuring an easy release film liner at 3.1 mil thickness. The tensile strength of 28 lb/in ensures durability and reliability in demanding industrial environments.
