3M 7100011639 Flame Resistant Hook Fastener 2in X 50yd

Product Description

The 3M 7100011639 is a flame resistant reclosable hook fastener roll designed for applications where fire safety compliance is required. Built on a woven nylon substrate, it uses a synthetic rubber-based adhesive that is formulated to resist flame spread. The roll measures 2 inches wide by 50 yards long and carries a beige finish. It meets the F.A.R. 25.853 paragraph (a)(1)(i) 60-second vertical burn test standard, making it appropriate for aerospace, transit, and other regulated environments. Installers and fabricators working in flame-rated assemblies rely on this fastener for reliable loop-and-hook closure without compromising compliance.

This fastener roll is suited for use in aerospace interiors, commercial transit vehicles, and any regulated installation where flame resistant reclosable fastening is specified. The hook side mates with the 3M SJ3518FR loop fastener to complete the closure system. It bonds to a wide range of surfaces including paper, cardboard, painted and bare metal, glass, sealed wood, and many plastics, making it adaptable to diverse panel and assembly applications across commercial and industrial settings.

Key Features

• Meets F.A.R. 25.853 paragraph (a)(1)(i) 60-second vertical burn test for flame resistance compliance
• Woven nylon hook construction for durable, repeatable open-and-close cycles
• Flame resistant synthetic rubber adhesive provides high-temperature performance
• Bonds to metal, glass, painted surfaces, sealed wood, cardboard, and many plastics
• Mates with 3M SJ3518FR loop fastener for a complete flame resistant closure system
• Continuous 50-yard roll allows field cutting to required lengths

Compatibility

Designed to mate with the 3M SJ3518FR flame resistant loop fastener as part of a reclosable hook-and-loop closure system.

Installation Notes

Surface preparation is critical before applying pressure-sensitive adhesive fasteners — clean surfaces should be free of dust, oil, and loose coatings. Apply firm, even pressure across the full bond area to ensure full adhesive contact. In regulated environments such as aerospace or transit, verify that the assembled installation meets the applicable flame resistance requirements of the governing authority. Cutting tools such as scissors or a utility knife are appropriate for sizing strips from the roll.
