Featuring interlocking mushroom-shaped heads with 170 stem density per square inch, this fastener delivers exceptional strength—up to 5X the tensile strength of typical hook-and-loop products. The synthetic rubber-based adhesive bonds reliably to a variety of substrates, including low surface energy plastics such as polyethylene and polypropylene, making it ideal for diverse industrial applications.\n \n This reclosable fastening system can be opened and closed multiple times without losing strength, supporting up to 1000 closure cycles. The fastener comes in a convenient 2-roll case with each roll measuring 0.75 inches wide by 50 yards long, featuring a black polyolefin backing and white polyolefin primary liner. Installation is quick and tool-free—no drilling, screwing, or sewing required. Simply peel away the removable film liner, apply the pressure-sensitive adhesive to your substrate, and press firmly for quick stick activation with short dwell time.\n \n Designed for indoor use with excellent temperature resistance up to 120°F (49°C), the SJ3542 produces an audible snap when properly secured, verifying closure and providing peace of mind. The fastener mates seamlessly with Type 250 and Type 400 stem densities to provide customizable strength combinations for varying project requirements. Ideal applications include access panels, interior signage, decorative trim, office partitions, and product identification. This hidden fastener provides a snug fit and smooth aesthetic appearance while maintaining the integrity of your materials.\n \u003c\/div\u003e\n \n \u003c!-- Features section (always included)
