This premium reclosable fastener consists of a synthetic rubber-based black polyethylene foam tape protected by a removable film liner. The pressure-sensitive adhesive features quick stick and short dwell time, enabling rapid installation without the need for drilling, screwing, or sewing tools. The fastener mates with Type 250 and Type 400 stem densities to provide different strength combinations, allowing customization for specific project requirements. With an audible snap verification upon closure and the ability to withstand up to 1000 closure cycles, this product delivers long-lasting performance and reliability.
The 3M™ Dual Lock™ Reclosable Fastener SJ3542 is engineered to bond well to a variety of substrates including low surface energy plastics such as polyethylene and polypropylene. Measuring 6 inches in width and 50 yards in length, this roll comes as a single unit per case. It features a maximum operating temperature of 120°F (49°C) and is best suited for indoor applications such as access panels, interior signage, decorative trim, office partitions, and product identification. The product maintains its aesthetic appeal by remaining hidden beneath surfaces while providing a snug fit without interfering with material integrity.
