3M™ Loop Fastener SJ3571

The 3M™ Loop Fastener SJ3571 is one part of a two-part fastener solution designed to provide great durability for thousands of closures. With its high-performance, acrylic-based, pressure-sensitive adhesive backing, this fastener allows for easy and convenient attachment to a variety of substrates, including some high surface energy plastics such as polycarbonate, acrylic, ABS, polystyrene.

The 3M™ Loop Fastener SJ3571 is a best in class acrylic based hook fastener with a 4 mil (0.10mm) polypropylene film liner featuring embossed 3M print. It is an attachment alternative to a wide variety of closures, including zippers, screws, snaps, hooks, and more. We designed this fastener with a woven loop backing, covered with thousands of soft, pliable napped loops, providing for thousands of openings and closings (cycles). Commonly paired with 3M™ Hook Fastener SJ3572, this loop fastener can also engage with other 3M™ Hook Fasteners. To ensure stability and flatness, both the hook and the corresponding loop are preshrunk.
