3M 7010330438 Weatherban Sealant Tape 5354 Black

Product Description

The 3M 7010330438 Weatherban Sealant Tape 5354 is a solid-extrusion, butyl-based sealing tape designed for weatherproofing and glazing applications in commercial and residential construction. It ships in a black formulation and measures 3/4 inches wide by 1/8 inches thick by 50 feet per roll. The tape is aggressively tacky out of the box, which means it conforms and adheres on contact without requiring a primer on most surfaces. Its low moisture vapor transmission rate helps prevent water intrusion at seams and joints. Cold flow resistance keeps the bead in place under sustained compression loads, making it a reliable choice where long-term seal integrity is required.

Weatherban Sealant Tape 5354 is suited for sealing glass-to-metal interfaces found in storefronts, curtain walls, window frames, and glazing systems. It also bonds to EPDM rubber, expanding its use to gasket-to-frame joints and certain roofing or panel applications. Glaziers, sheet metal contractors, and general construction trades typically specify this tape when a conformable, non-curing sealant bead is needed in place of wet-applied caulk. Each roll provides 50 feet of coverage, making it practical for both small repair work and production glazing runs.

Key Features

• Aggressively tacky solid extrusion — bonds on contact to glass and metal without primer
• Exceptional cold flow resistance — maintains seal geometry under sustained compression
• Low moisture vapor transmission — limits water intrusion at sealed joints
• Adheres to EPDM rubber as well as glass and metal substrates
• Black formulation — 3/4 inches wide, 1/8 inches thick, 50 feet per roll

Compatibility

Designed for sealing applications between glass and metal substrates and compatible with EPDM rubber surfaces. Suitable for glazing, curtain wall, and weatherproofing assemblies where a solid butyl sealant tape is specified.

Installation Notes

This tape is installed by glaziers and sheet metal contractors as part of window, storefront, or panel assembly work. Surface should be clean, dry, and free of oils or loose debris before application. Apply consistent pressure across the full length of the tape to activate tack and achieve full contact. Do not stretch the tape during installation, as elongation can reduce cross-sectional thickness and compromise the sealed joint.
