3M 7010337274 Aluminum Foil Tape 3/4 in X 60 Yd Silver

Product Description

The 3M 7010337274 is a dead soft aluminum foil tape with a pressure-sensitive acrylic adhesive backing, designed for demanding sealing, seaming, heat shielding, and chemical masking applications across HVAC, industrial, and specialty trade work. The aluminum foil construction is thermally conductive, allowing it to dissipate heat and reflect light effectively. The acrylic adhesive bonds durably over time but releases cleanly after masking operations. The tape measures 3/4 inch wide and runs 60 yards per roll, making it well-suited for repetitive sealing runs and detail work on irregular surfaces.

This tape is used in HVAC ductwork sealing, heat shield fabrication, light enhancement setups, chemical milling masking, and de-paint operations. The dead soft foil backing conforms to curved and uneven surfaces without cracking or lifting, which makes it practical for wrapping fittings, seaming insulation, and covering contoured components. It withstands exposure to flame, UV, moisture, and weathering, making it a reliable choice in both indoor mechanical spaces and outdoor or semi-exposed environments. HVAC technicians, sheet metal workers, and industrial maintenance crews are the primary installers.

Key Features

• Dead soft aluminum foil backing conforms to curved and uneven surfaces without splitting
• Thermally conductive construction helps dissipate heat and improves heating and cooling efficiency
• Pressure-sensitive acrylic adhesive bonds long term and removes cleanly after masking applications
• Resistant to chemicals, moisture, UV, weathering, and flame exposure
• Heat and light reflective surface protects temperature-sensitive materials and enhances lighting efficiency
• UL Recognized to UL 746C and UL Classified to UL 723, Class L low flammability rating

Compatibility

Designed for use in HVAC duct sealing, thermal insulation seaming, heat shielding, chemical masking, chemical milling, and light-enhancement applications across residential and commercial installations.

Installation Notes

This tape is typically applied by HVAC technicians, sheet metal workers, and industrial maintenance professionals. Surfaces should be clean, dry, and free of oil or loose debris before application to ensure full adhesive contact. Apply firm hand pressure or use a roller to fully seat the tape, especially on curved or textured surfaces. When used for chemical masking or de-paint operations, verify chemical compatibility before extended exposure.
