3M 7010379738 Aluminum Foil Tape 3.5 in X 60 Yd Acrylic

Product Description

The 3M 7010379738 is a dead-soft aluminum foil tape with a pressure-sensitive acrylic adhesive designed for demanding thermal, chemical, and surface-protection applications across HVAC, industrial, and aerospace trades. The aluminum foil backing conforms to curved and irregular surfaces, while the acrylic adhesive bonds aggressively under service conditions yet releases cleanly after masking operations. At 3.5 inches wide and 60 yards long per roll, this tape covers large seaming and sealing jobs without frequent splicing. It withstands exposure to flame, moisture, UV radiation, and weathering, making it a reliable choice wherever foil tape must perform long-term in harsh environments.

This tape is used in HVAC duct seaming and sealing, heat shielding, heat reflection, light enhancement, chemical masking, chemical milling, and de-paint operations. It is suited for both residential and commercial mechanical systems as well as industrial and manufacturing environments. HVAC technicians use it to seal duct joints and insulation seams. Industrial and aerospace technicians rely on it for chemical masking during de-paint and surface-treatment processes. Its thermal conductivity helps dissipate heat and improves heating and cooling efficiency around temperature-sensitive components.

Key Features

• Dead-soft aluminum foil backing conforms to curved and uneven surfaces for complete coverage
• Pressure-sensitive acrylic adhesive provides long-term durability and clean removal after masking
• Thermally conductive construction dissipates heat and supports heating and cooling efficiency
• Resistant to chemicals, flame, moisture, UV radiation, and weathering
• Heat and light reflective surface protects adjacent 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 as a general-purpose aluminum foil tape in HVAC duct sealing, insulation seaming, heat shielding, chemical masking, and surface-protection applications across residential, commercial, and industrial installations.

Installation Notes

Installation is performed by HVAC technicians, sheet metal workers, and industrial maintenance personnel. Power down or de-energize any associated equipment before applying tape near electrical or thermal components. Surfaces should be clean, dry, and free of dust or oils before application to ensure full adhesive contact. Consult applicable mechanical codes and manufacturer guidelines for duct sealing requirements in your jurisdiction.
