3M 7010374390 Aluminum Foil Tape 8 in X 60 Yd Silicone

Product Description

The 3M 7010374390 is a high-temperature aluminum foil tape designed for heat shielding and thermal insulation applications in HVAC, aerospace, and industrial environments. The tape features a dead-soft aluminum foil backing coated with a clear silicone pressure-sensitive adhesive that maintains a strong bond at elevated temperatures where standard acrylic or rubber-based adhesive tapes would fail. It is thermally conductive, helping to dissipate heat away from temperature-sensitive components and materials. HVAC technicians, insulation contractors, and industrial maintenance trades install this tape where reliable performance at extreme temperatures is required.

This tape is suited for wrapping over and along thermal insulation, sealing ductwork jacketing, and protecting heat-sensitive surfaces in both residential and commercial mechanical systems. Its linered construction makes it a field-friendly alternative to the unlinered 3M 433, allowing for cleaner handling and precise placement on curved or uneven surfaces. Typical applications include heat blanket fabrication, exhaust and engine bay heat shielding, and high-temperature duct sealing where silicone adhesive performance is specified.

Key Features

• Withstands limited exposure up to 600 degrees F / 316 degrees C for heat shielding applications
• Thermally conductive backing dissipates heat to protect temperature-sensitive materials
• Dead-soft aluminum foil conforms to curved and irregular surfaces
• Clear silicone pressure-sensitive adhesive bonds to a wide variety of substrates
• Flame resistant, meeting F.A.R. 25.853(a) requirements
• UL Recognized component (file QQQW2.MH122798)
• Linered version of 3M 433 for easier handling and application

Compatibility

Designed for high-temperature heat shielding and insulation wrap applications; compatible with a broad range of smooth, semi-smooth, and irregular surfaces where silicone adhesive tapes are specified.

Installation Notes

This tape is installed by HVAC technicians, insulation mechanics, and industrial maintenance personnel. Ensure the application surface is clean, dry, and free of oils or loose debris before applying. When used in duct or HVAC insulation applications, follow applicable mechanical codes and manufacturer installation guidelines for tape overlap and seam coverage. Do not exceed the rated temperature exposure limits for sustained service.
