3M 7100053630 Aluminum Foil Tape 2in 4.6mil Series 425

Product Description

The 3M 7100053630 is a silver aluminum foil tape from the 3M 425 Series, engineered for demanding sealing, seaming, and joining applications in HVAC, sheet metal, and industrial environments. It features a 4.6 mil total thickness and an acrylic adhesive backing that bonds firmly to metal, foil-faced insulation, and similar surfaces. The tape delivers 30 pounds per inch of tensile strength and an operating temperature range of -65.2 degrees F to 300 degrees F, making it suitable for both low-temperature duct work and high-heat reflective applications. Licensed HVAC technicians and sheet metal workers are the primary installers of this product type.

This tape is used across residential and commercial HVAC installations for duct sealing, insulation seaming, heat reflecting, and splicing foil-faced materials. It is also applicable in chemical stripping protection, holding, and joining tasks where a conformable, thermally stable foil tape is required. The roll measures 2 inches wide and 55 meters (approximately 60 yards) in length, providing substantial coverage per roll for multi-joint duct projects or large insulation seaming jobs.

Key Features

• 4.6 mil total thickness with aluminum foil construction for conformability and tear resistance
• Acrylic adhesive provides strong, long-term bond to metal and foil-faced surfaces
• 30 lb per inch tensile strength for secure holding in high-stress seam applications
• Operating range of -65.2 degrees F to 300 degrees F suits both cold and hot system environments
• Meets F.A.R. 25.853(a), L-T-80B, SAE-AMS-T-23397, UL 723, and UL 746C standards
• Suitable for sealing, seaming, splicing, heat reflecting, joining, holding, and chemical stripping applications

Compatibility

Designed as an OEM-style foil tape for use on HVAC ductwork, foil-faced insulation, sheet metal joints, and similar surfaces requiring a thermally stable, pressure-sensitive aluminum foil tape.

Installation Notes

Installation is typically performed by licensed HVAC technicians or sheet metal workers. Surfaces should be clean, dry, and free of dust or grease before application to ensure full adhesive contact. Power down and lock out any associated HVAC or mechanical system before working in confined duct spaces. Follow applicable mechanical codes and manufacturer surface-preparation guidance for permanent duct sealing installations.
