Premium thermally conductive aluminum foil tape with acrylic adhesive for heat shielding, chemical masking, and industrial sealing applications. UL certified, temperature range -65°F to 300°F, 3 inches x 60 yards, 16 rolls per case.
3M™ Aluminum Foil Tape 427 is a premium industrial-grade foil tape engineered for demanding applications requiring heat dissipation, chemical resistance, and reliable adhesion. This linered version 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 is thermally conductive and helps dissipate heat to reduce hot spots while protecting temperature-sensitive materials from high-temperature exposure.
With exceptional durability and versatility, 3M Aluminum Foil Tape 427 withstands exposure to high heat, humidity, moisture, weathering, UV radiation, and solvents. The acrylic adhesive provides long-term durability while removing cleanly after harsh masking applications, making it suitable for both temporary and permanent installations. The dead soft aluminum foil backing conforms easily to curved and uneven surfaces, ensuring excellent coverage and adhesion even on complex geometries. This 3-inch wide tape comes in 60-yard rolls with a 4.6 mil total thickness, packaged 16 rolls per case for industrial and occupational use.
Recognized by UL to UL 746C and classified by UL to UL 723 Class L for low flammability rating, this tape meets FAR 25.853(a) specifications and operates reliably across a wide temperature range from -65°F to 300°F (-54°C to 149°C). Ideal applications include heat shielding of delicate parts, refrigerator and freezer coil attachment, HVAC duct sealing, wiring harness attachment, and moisture barrier applications across aerospace, automotive, appliance, construction, electronics, and metalworking industries.
