3M 7010378529 Aluminum Foil Tape 6 Inch 60 Yd Acrylic

Product Description

The 3M 7010378529 is a dead-soft aluminum foil tape with a pressure-sensitive acrylic adhesive, designed for heat shielding, heat reflecting, chemical masking, seaming, sealing, and de-paint operations. At 6 inches wide and 60 yards long, it delivers ample coverage for demanding industrial and trade applications. The thermally conductive aluminum backing helps dissipate heat and improves heating and cooling efficiency, protecting temperature-sensitive materials in environments where foil tape is a critical component of the install or surface-protection process.

This tape is used across HVAC, electrical, aerospace, and general industrial applications where a reliable, chemically resistant foil tape is required. Its dead-soft aluminum foil backing conforms readily to curved, irregular, and uneven surfaces, making it suitable for duct seaming, heat shield fabrication, light-reflective work, and chemical milling masking. HVAC technicians commonly use this product for sealing sheet metal duct assemblies and lining penetrations where thermal performance and long-term adhesion are priorities.

Key Features

• Dead-soft aluminum foil backing conforms to curved and uneven surfaces
• Pressure-sensitive acrylic adhesive provides long-term durability and removes cleanly after masking applications
• Thermally conductive construction helps dissipate heat and improves heating and cooling efficiency
• Resistant to chemicals, flame, weathering, moisture, and UV exposure
• Heat and light reflective surface protects adjacent materials and enhances lighting efficiency
• Linered construction for controlled application during precision masking operations

Compatibility

Designed for use in HVAC duct sealing, heat shielding, chemical masking, seaming, and light-enhancement applications across industrial and trade environments.

Installation Notes

This tape is typically applied by HVAC technicians, sheet metal workers, and industrial maintenance trades. Ensure the substrate surface is clean, dry, and free of grease or dust before application for maximum adhesion. Apply firm, even pressure across the full tape width to seat the acrylic adhesive. When used in chemical masking operations, verify tape edges are fully sealed to prevent chemical migration beneath the tape.
