3M™ Dual Lock™ Reclosable Fastener SJ3540 is the easy and clear alternative to traditional fastening methods, such as screws, nuts or bolts. It is designed to deliver a durable, reclosable fastening solution that can be opened and closed multiple times, bonding to a variety of substrates, including many plastics and low surface energy materials. Durable and secure, the 3M™ Dual Lock™ Reclosable Fastener SJ3542 has exceptional strength through its interlocking mushroom-shaped heads (250 stem density per square inch), providing up to 5X the tensile strength of typical hook-and-loop products. We designed this fastener with a synthetic, rubber-based PE foam tape protected by a removable film liner. This pressure-sensitive adhesive features quick stick and a short dwell time. With 3M™ Dual Lock™ Reclosable Fastener SJ3542, there is no need for any drilling, screwing or sewing tools which makes for quick installation.
