3M Scotch SJ3571 / SJ3572 Scotchmate Fasteners: 1 in x 50 yds. (Black) *loop-side only - OEM

3M SJ3571 and SJ3572 Scotchmate Hook and Loop Fasteners are premium performance, pressure-sensitive adhesive (PSA) nylon hook and loop tapes coated with a high-performance acrylic adhesive. They offer advanced closure alternatives to zippers, screws, snaps, hooks and more. The tape is designed for static load applications requiring high adhesion and UV and temperature resistance. Its woven nylon backing is durable for thousands of closures.

3M hook and loop can secure fabric to furniture cushions, airplane seating, carpet panel attachments, uniforms, and gloves and clothing.

It is used in the aerospace, electronics, construction, specialty vehicle, military, medical, furniture, and general industrial markets. Stiff hooks on one side of the fastener mesh with pliable loops on the other side for secure closure; peel one side away to open. As with all reclosable fasteners, the larger the fastener area, the greater the strength for holding weight and resisting shear and peel.

The acrylic adhesive used on 3M SJ3571 and SJ3572 provides fair initial adhesion and excellent moisture, UV and solvent resistance.

Approximately 50% of ultimate bond strength is achieved at room temperature in the first 20 minutes, 90% after about 24 hours and 100% after about 72 hours for this acrylic adhesive. Bonds well to high surface energy materials including bare and painted (non-powder coated) metals, glass, sealed wood. paint and many HSE plastics (such as acrylic, polycarbonate, polystyrene, and rigid vinyl - not to LSE plastics such as polypropylene and polyethylene). These adhesive-backed reclosable fasteners should be applied to surfaces that are smooth, dry and free of oils, mold release agents or other surface contaminants.

3M SJ3571 and SJ3572 Scotchmate Hook and Loop Fasteners have a woven nylon hook backing that has flexible, self-supporting inverted J-hooks protruding up from the backing. There are approximately 300 hooks per square inch. 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.

As a general rule, four square inches of Scotchmate reclosable fastener area per pound of static load to be supported is suggested as a starting point for evaluation.

More or less area may be needed depending on specific conditions or end-use applications.
