3M SJ3571

3M Re closable Fasteners offer advanced closure alternatives to zippers, screws, snaps, hooks and more. They offer greater design flexibility, faster product assembly, smoother and cleaner exterior surfaces and improved product performance in many applications. Scotchmate re-closable fasteners consist of nylon fabric with hooks or loops. They engage to form a quick fastening attachment. Simply pull the strips apart by hand to disengage The woven nylon hook backing has flexible, self-supporting inverted J-hooks protruding up from the backing. There are approximately 300 hooks per square inch (46 hooks/square cm). The woven nylon loop backing has thousands of soft, pliable napped loops protruding above the backing, providing for thousands of openings and closings (cycles). The hook and loop are preshrunk to ensure maximum dimensional stability and flatness.

These hook and loop fasteners are coated on the backside with a high temperature acrylic pressure sensitive adhesive designed to function over a range of temperatures and humidity. This adhesive is especially suited for attachment to bare metals and a variety of high surface energy adherends. For attachment to powder coated paints or other low surface energy materials such as polyethylene or polypropylene, the use of adhesion promoters may be necessary or you can evaluate our line of Scotchmate fasteners with rubber based adhesives such as 3M Scotchmate Re closable Fastener SJ3518°FR or SJ3532N.

The loop is available with a fabricator splice. This consists of the adhesive side of the Scotchmate re closable fastener and the liner being spliced. This provides product and liner continuity on the roll. This product is ordered as SJ3571FS. When it is desired to have marked the splices, the loop product can be ordered as SJ3571FSR.

Scotchmate re closable fastener SJ3571 is also available with a brown 83 pound poly kraft paper liner allowing easier die-cutting. The product number with the paper liner is SJ3571P.
