3M 7010379578 Aluminum Foil Tape 3.78 in X 60.14 Yd 4.6 Mil

Product Description

The 3M 7010379578 is a dead-soft aluminum foil tape built for demanding industrial and HVAC applications. The foil backing is coated with a pressure-sensitive acrylic adhesive that bonds firmly under a wide range of conditions and still removes cleanly after harsh masking work. At 4.6 mil total thickness, the tape delivers reliable conformability over curved and uneven surfaces. It handles heat shielding, heat reflecting, light enhancement, chemical masking, seaming, sealing, and de-paint operations. Qualified technicians and tradespeople working across HVAC, aerospace, and general industrial settings rely on this tape where durability, chemical resistance, and thermal performance are all required.

This tape is well suited for residential and commercial HVAC duct sealing and seaming, as well as chemical masking in industrial manufacturing environments. The acrylic adhesive system maintains adhesion through temperature cycling, moisture exposure, UV, and weathering. The dead-soft foil backing conforms readily to irregular substrate geometry, making it practical for wrapping insulation, patching duct work, and surface protection tasks during de-paint or chemical milling operations. It is packaged as a single roll measuring 3.78 inches wide by 60.14 yards long.

Key Features

• Dead-soft aluminum foil backing conforms to curved and irregular surfaces
• Pressure-sensitive acrylic adhesive provides long-term bond strength and clean removal after masking
• Thermally conductive construction helps dissipate heat and supports heating and cooling efficiency
• Resistant to flame, weathering, moisture, and UV exposure
• Heat and light reflective surface protects substrates 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 seaming and sealing, heat shielding, chemical masking, chemical milling, de-paint operations, and light-enhancement applications across a broad range of industrial and trade settings.

Installation Notes

Installation is typically performed by HVAC technicians, sheet metal workers, or qualified industrial maintenance personnel. De-energize or shut down any associated HVAC equipment before applying tape to duct seams or insulation surfaces. Ensure the substrate is clean, dry, and free of dust or grease before application to achieve full adhesive contact. When used in chemical masking or de-paint operations, follow all applicable site safety protocols and material handling guidelines.
