3M 7100053645 Aluminum Foil Tape 0.5 in X 60 Yd Acrylic

Product Description

The 3M 7100053645 is an aluminum foil tape engineered for demanding thermal, chemical, and sealing applications across HVAC, industrial, and specialty trade work. It features a dead soft aluminum foil backing coated with a pressure-sensitive acrylic adhesive. The dead soft construction allows the tape to conform to curved and irregular surfaces without lifting or creasing. The acrylic adhesive delivers long-term bond strength while still removing cleanly after masking operations. This tape is rated for heat shielding, heat reflecting, seaming, sealing, chemical masking, chemical milling, light enhancement, and de-paint operations.

This tape is a common choice for HVAC technicians sealing ductwork, sheet metal seams, and insulation jacketing. It also sees use in industrial and aerospace chemical masking, de-paint operations, and light-reflective applications. The 0.5-inch width suits tight seams and detail work where wider tapes are impractical. Each roll provides 60 yards of usable length. The aluminum foil construction withstands exposure to flame, weathering, moisture, and UV, making it suitable for both indoor and outdoor installations.

Key Features

• Dead soft aluminum foil backing conforms to curved and uneven surfaces
• Pressure-sensitive acrylic adhesive bonds long-term and removes cleanly after masking use
• 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 adjacent materials and improves lighting efficiency
• UL recognized to UL 746C and UL classified to UL 723 Class L low flammability rating
• Contains a plastic core center for consistent unwind and roll integrity

Compatibility

Designed for use in HVAC duct sealing, sheet metal work, insulation jacketing, chemical masking, and light-reflective applications requiring a conformable aluminum foil tape with acrylic adhesive.

Installation Notes

Installation is typically performed by HVAC technicians, sheet metal workers, or industrial maintenance personnel. Ensure the application surface is clean, dry, and free of oils or loose material before applying the tape for maximum adhesion. When used in duct sealing applications, follow applicable mechanical codes and manufacturer guidelines for approved sealing methods. Avoid stretching the foil backing during application to prevent tearing or loss of adhesion at seams.
