3M 7100059421 Aluminum Foil Tape 1 Inch X 60 Yards

Product Description

The 3M 7100059421 is a dead-soft aluminum foil tape with a pressure-sensitive acrylic adhesive, supplied in a 1-inch-wide by 60-yard roll. It is designed for heat shielding, heat reflecting, seaming, sealing, chemical masking, chemical milling, light enhancement, and de-paint operations across HVAC, aerospace, electronics, and industrial applications. The dead-soft foil backing conforms readily to curved and irregular surfaces. The thermally conductive construction helps dissipate heat and improves heating and cooling efficiency. UL recognition to UL 746C and UL 723 Class L for low flammability makes this tape suitable for installations where fire and safety standards apply.

This tape is widely used in HVAC ductwork seaming and sealing, heat shielding around temperature-sensitive components, and chemical masking during industrial surface prep and de-paint processes. It performs across a broad range of industries wherever a conformable, chemically resistant, thermally reflective foil tape is needed. HVAC technicians commonly use it for duct sealing and insulation facing repairs. Industrial and maintenance trades rely on it for masking and surface protection during chemical processing operations.

Key Features

• Dead-soft aluminum foil backing conforms to curved, irregular, and uneven surfaces
• Thermally conductive construction dissipates heat and improves heating and cooling efficiency
• Pressure-sensitive acrylic adhesive provides long-term durability and removes cleanly after masking applications
• Resistant to flame, weathering, moisture, and UV 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
• Plastic core center for roll integrity during dispensing

Compatibility

Designed for use across HVAC, aerospace, electronics, and general industrial applications requiring a conformable, heat-reflective, chemically resistant aluminum foil tape.

Installation Notes

Surface must be clean, dry, and free of oils or loose material before application to ensure full adhesive contact. Apply firm pressure across the full tape width using a roller or squeegee for maximum bond. No power shutoff is required for most tape applications, but follow applicable site safety protocols when working near energized equipment or HVAC systems under pressure. Consult local mechanical codes and manufacturer guidelines for duct sealing applications where tape ratings are specified.
