Industrial-grade aluminum foil tape with thermally conductive acrylic adhesive for heat shielding, masking, and sealing applications. Temperature range -65°F to 300°F, UL certified, 24 rolls per case.
3M™ Aluminum Foil Tape 425 is a premium industrial-grade adhesive tape designed for demanding applications across aerospace, automotive, construction, and electronics industries. This versatile foil tape features a dead soft aluminum foil backing that is thermally conductive and heat reflective, combined with a highly engineered acrylic pressure-sensitive adhesive. The tape excels at dissipating heat, reducing hot spots, and protecting temperature-sensitive materials from thermal damage. With a temperature operating range from -65°F to 300°F (-54°C to 149°C), it provides reliable performance in extreme conditions. The dead soft aluminum backing conforms easily to curved and uneven surfaces, making it ideal for complex geometries and irregular applications.
This professional-grade tape is specifically engineered for heat shielding, heat reflecting, chemical masking, light enhancement, chemical milling, seaming, sealing, and de-paint operations. It withstands exposure to high humidity, moisture, weathering, UV radiation, and various solvents, ensuring excellent work life both indoors and outdoors. The tape is resistant to chemicals, protecting surfaces during de-paint processes and other chemical masking operations. Its highly engineered acrylic adhesive provides long-term durability and maintains a strong, reliable bond even under harsh conditions, while still removing cleanly after masking applications.
3M™ Aluminum Foil Tape 425 meets stringent industry standards and certifications, including UL Recognition to UL 746C (File E 122798) and UL Classification to UL 723 "L" for low flammability rating (File R 7311). It meets F.A.R 25.853(a) and L-T-80C specifications, making it suitable for aerospace and aviation applications. Each case contains 24 rolls, with each roll measuring 2 inches wide by 60 yards long with a 4.6 mil total thickness. This product is intended for industrial and occupational use only.
