Delivers Durability 3M™ Hook/Loop Fastener TB3571/TB3572 is our best in class hook and loop fastener that features 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 nylon loop backing, covered with thousands of soft, pliable napped loops, providing for thousands of openings and closings (cycles). This fastener is also covered with flexible J-shaped hooks, about 300 hooks per square inch (46 hooks/square cm.), which protrude up from a woven backing. To ensure stability and flatness, both the hook and the corresponding loop are preshrunk.

High Performance Acrylic Adhesive The backings of 3M™ Hook/Loop Fastener TB3571/TB3572 are 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.
