3M 7000046616 Weatherban Sealant Tape 5354 Black

Product Description

The 3M 7000046616 Weatherban Sealant Tape 5354 is a solid butyl rubber extrusion tape used to create weathertight seals between glass, metal, and EPDM rubber surfaces. Black in color and aggressively tacky, this tape conforms readily to irregular surfaces and delivers consistent compression sealing across a wide range of temperatures. Key performance characteristics include exceptional cold flow resistance and low moisture vapor transmission, making it a reliable choice where water intrusion and air infiltration control are critical. It is typically installed by glaziers, construction tradespeople, and HVAC technicians working on fenestration, curtain wall, and mechanical enclosure applications.

This tape is suited for sealing joints and gaps in both residential and commercial construction and mechanical applications. It performs in glass-to-frame assemblies, metal panel joints, and anywhere a flexible, long-term sealant tape is required. Its adhesion to EPDM rubber expands its use to gasket-style sealing scenarios common in HVAC equipment enclosures and rooftop unit curb assemblies. Each roll measures 0.25 inches wide by 0.125 inches thick by 50 feet long, providing substantial coverage per unit.

Key Features

• Aggressive tack for immediate adhesion to glass, metal, and EPDM rubber substrates
• Exceptional cold flow resistance maintains seal integrity under compression and thermal cycling
• Low moisture vapor transmission rate reduces water intrusion risk at sealed joints
• Solid butyl extrusion format for consistent cross-section and predictable compression behavior
• Black color blends with common frame and gasket materials in commercial glazing and HVAC applications

Compatibility

Designed for sealing applications between glass and metal surfaces and adheres to EPDM rubber. Suitable for glazing, curtain wall, metal panel, and HVAC enclosure sealing applications where a flexible butyl sealant tape is required.

Installation Notes

Surface preparation is critical — clean and dry all substrates before application to ensure full adhesion. Apply tape with firm, even pressure to achieve full contact with the mating surface before compression. Wear appropriate PPE when working with adhesive tapes in overhead or confined spaces. Follow applicable building codes and manufacturer assembly guidelines for glazing and curtain wall systems.
