It is an attachment alternative to a wide variety of closures, including zippers, screws, snaps, hooks and more. This fastener is covered with flexible J-shaped hooks, about 300 hooks per square inch (46 hooks/square cm.), which protrude up from a woven backing. This fastener should be paired with 3M™ Flame Resistant Loop Fastener SJ3418FR. To ensure stability and flatness, both the hook and the corresponding loop are preshrunk.

No Adhesive or Liner for Easy Customization
The backing of 3M™ Flame Resistant Hook Fastener SJ3419FR is free of adhesive or liner, allowing for easy customization. The fastener is most commonly attached by sewing, but can also be applied using hot melt or liquid adhesives (temperature and flame resistance may change based on adhesive used). It provides a tailored appearance for fabrics and garments and is both washable and dry cleanable.
Secure, Repeated Closures
3M™ Hook and Loop Fasteners offer great design flexibility, fast product assembly, smooth and clean exterior surfaces and excellent product performance in many applications. 3M Hook and Loop Fasteners consist of hooks and loops which engage to form a quick fastening attachment.

Backed with a variety of 3M adhesive technologies, you can easily meet application demands that require thousands of easy opening and closings.
