Delivers Durability
3M™ Loop Fastener SJ3571 is our 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.

High Performance Acrylic Adhesive
The backing of 3M™ Loop Fastener SJ3571 is coated with a high performance acrylic-based pressure sensitive adhesive. This adhesive strength builds up over time allowing for some repositionability before achieving full bond strength. The adhesive bonds well to high and medium surface energy substrates, such as clean, dry metals and some low surface energy substrates such as polycarbonate, polystyrene, acrylic and nylon. It boasts excellent heat and moisture resistance as well as UV stability and excellent shear strength.
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. To disengage the attachment, simply pull the strips apart by hand.
The use of a pressure sensitive adhesive reduces or eliminates the need for sewing, solvent activation, dielectric or ultrasonic bonding or bulk adhesive bonding. Pressure sensitive adhesive products can be applied manually or automatically using a variety of equipment choices.
Bringing it All Together
3M™ Hook and Loop Fasteners provide the strong, tough attachment solutions you need. Simply press together and the tiny, stiff hooks mesh with pliable loops to create a quick, secure fastening system. Backed with a variety of 3M adhesive technologies, you can easily meet application demands that require thousands of easy opening and closings.
