3M 7010334620 Aluminum Foil Tape 433L 6 Inch X 60 Yd

Product Description

The 3M 7010334620 is a high-temperature aluminum foil tape designed for heat shielding applications in HVAC, aerospace, and industrial settings. It features a dead soft aluminum foil backing coated with a clear silicone pressure-sensitive adhesive, allowing it to conform to curved and irregular surfaces while maintaining a strong bond across a wide temperature range. The tape can withstand limited exposure up to 600 degrees F (316 degrees C), making it suitable for thermal insulation wrapping, heat dissipation, and applications where standard acrylic-adhesive tapes fail. This is the linered version of the 3M 433 tape, which simplifies handling and application during installation.

This tape is used primarily in HVAC duct sealing, heat shield wrapping, and thermal insulation jacketing applications. It is appropriate for both residential and commercial installations where thermally conductive, flame-resistant tape is required. Its ability to improve heating and cooling efficiency by reducing heat loss makes it a common choice for insulation contractors, sheet metal mechanics, and HVAC service technicians working on duct systems and equipment enclosures.

Key Features

• Withstands limited exposure up to 600 degrees F (316 degrees C) for heat shielding service
• Dead soft aluminum foil backing conforms to curved and uneven surfaces
• Clear silicone pressure-sensitive adhesive bonds to a variety of substrates
• Thermally conductive construction helps dissipate heat and protect temperature-sensitive materials
• Flame resistant — meets F.A.R. 25.853(a) requirements
• UL Recognized component (file QQQW2.MH122798)
• Linered design for easier handling and precise placement during installation

Compatibility

Designed for heat shielding and thermal insulation wrapping applications where a high-temperature, silicone-adhesive aluminum foil tape is required.

Installation Notes

Installation is typically performed by HVAC technicians, insulation contractors, or sheet metal mechanics. Power down or shut off any associated HVAC equipment before applying tape to ductwork or equipment surfaces. Ensure surfaces are clean, dry, and free of dust or oil before application to achieve full adhesive contact. Consult applicable mechanical codes and manufacturer guidelines for duct sealing requirements in your jurisdiction.
