3M 7100142835 Aluminum Foil Tape 3 in X 60 Yd Acrylic

Product Description

The 3M 7100142835 is a dead-soft aluminum foil tape with a pressure-sensitive acrylic adhesive, designed for demanding thermal management, masking, and sealing applications across trade and industrial settings. The aluminum foil backing conforms readily to curved and uneven surfaces, making it well suited for ductwork seams, heat shielding runs, and chemical masking work. The acrylic adhesive delivers long-term bond strength while still releasing cleanly after harsh masking operations. This tape is 3 inches wide and 60 yards long per roll, supplied on a liner as the linered counterpart to the 3M 425 foil tape.

This tape is used across HVAC, aerospace, manufacturing, and general trade applications where heat reflection, chemical resistance, or moisture sealing is required. Typical HVAC uses include seaming and sealing sheet metal ductwork, wrapping heat-sensitive components, and light-enhancement work in plenum spaces. It also sees use in chemical milling and de-paint masking operations where a durable, chemically resistant barrier is needed. Installation is performed by HVAC technicians, sheet metal workers, and industrial maintenance trades.

Key Features

• Dead-soft aluminum foil backing conforms to curved and irregular surfaces
• Pressure-sensitive acrylic adhesive bonds firmly 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
• Reflective surface shields heat and enhances lighting efficiency in applicable installations
• Chemically resistant for use in de-paint and chemical masking operations

Compatibility

Designed as a linered foil tape suitable for heat shielding, seaming, sealing, and chemical masking applications across HVAC, industrial, and general trade use.

Installation Notes

Apply to clean, dry surfaces free of oil, dust, and loose material for best adhesion. No special tools are required beyond a tape measure, cutting tool, and roller or squeegee for firm seating. When used on HVAC ductwork, verify that the installation meets local code requirements and applicable standards for duct sealing materials. Avoid stretching the foil during application to prevent adhesive voids at seams.
