3M 7010379708 Aluminum Foil Tape 2.5 in X 60 Yd

Product Description

The 3M 7010379708 is a heavy-duty aluminum foil tape engineered for heat shielding, heat reflection, seaming, and sealing in demanding trade applications. It features a dead-soft aluminum foil backing paired with a pressure-sensitive acrylic adhesive that delivers long-term durability while still removing cleanly after masking use. The tape measures 2.5 inches wide and 60 yards long per roll. It withstands exposure to flame, weathering, moisture, and UV, making it well suited for high-temperature and outdoor service environments. HVAC technicians, sheet metal contractors, and industrial maintenance professionals are the primary installers of this product.

This tape is used across HVAC ductwork fabrication and repair, insulation seaming, heat shield fabrication, and reflective surface applications in both residential and commercial settings. Its foil construction reflects heat and light, which supports energy efficiency in duct systems and protects adjacent surfaces from radiant heat. The acrylic adhesive bonds to metal, glass, and most rigid substrates commonly encountered in mechanical and industrial work.

Key Features

• Dead-soft aluminum foil backing conforms to irregular surfaces for effective heat shielding
• Pressure-sensitive acrylic adhesive provides long-term hold and clean removal after masking
• Resists flame, UV, moisture, and weathering for outdoor and high-temperature service
• Heat and light reflective surface protects substrates and supports lighting or thermal efficiency
• UL Recognized to UL 746C and UL Classified to UL 723 Class L for low flammability

Compatibility

Designed for use on metal ductwork, rigid insulation, glass, and other hard substrates in HVAC, sheet metal, and industrial maintenance applications where a foil tape with pressure-sensitive acrylic adhesive is specified.

Installation Notes

This tape is typically applied by HVAC technicians or sheet metal workers using a tape roller or seam roller to ensure full adhesive contact. Surfaces should be clean, dry, and free of dust or grease before application for best adhesion. No tools beyond a utility knife and roller are generally required. Follow all applicable mechanical and building codes when sealing ductwork or installing heat shielding assemblies.
