3M 7010375464 Aluminum Foil Tape 4380 1 Inch 55 Yd

Product Description

The 3M 7010375464 is a self-wound aluminum foil tape in the 4380 series, combining a malleable aluminum foil backing with a pressure-sensitive acrylic adhesive. Designed for general purpose sealing, holding, splicing, and masking, this tape provides reliable protection in applications where resistance to heat or flame is required. The foil construction is thermally conductive, helping to reflect and dissipate radiant heat away from sensitive components or surfaces. HVAC technicians, sheet metal workers, and industrial maintenance professionals install this tape where a conformable, durable foil solution is needed on irregular or flat surfaces.

This tape is suited for both residential and light commercial applications including ductwork sealing, insulation facing repair, heat shielding, and surface masking during high-temperature processes. The acrylic adhesive maintains bond integrity across a wide range of indoor and outdoor conditions, making it appropriate for installations subject to moisture, UV exposure, and chemical contact. It conforms well to contoured or uneven surfaces where rigid tapes would bridge or lift.

Key Features

• Aluminum foil backing resists flame, moisture, weather, UV degradation, and many chemicals
• Thermally conductive construction reflects and dissipates radiant heat to protect heat-sensitive components
• Malleable foil conforms to irregular shapes and surfaces without bridging
• Low moisture vapor transmission rate for effective sealing and patching
• Pressure-sensitive acrylic adhesive for reliable bond without heat activation
• Self-wound roll construction with no liner waste

Compatibility

Designed as a general purpose aluminum foil tape suitable for ductwork, insulation, sheet metal, and heat shielding applications in HVAC, industrial, and construction environments.

Installation Notes

Surface should be clean, dry, and free of oils or loose material before application to ensure full adhesive contact. Apply firm hand pressure or use a roller to seat the tape fully, particularly on contoured surfaces. No special tools are required, though a tape dispenser or utility knife is recommended for clean cuts. Remove power or shut down HVAC equipment before applying tape to active duct systems or near energized components.
