Premium black woven nylon loop fastener with high-performance acrylic adhesive for 5000+ closure cycles. Ideal for industrial, marine, and specialty vehicle applications with excellent temperature and moisture resistance.
The 3M™ Loop Fastener SJ3571 is a premium reclosable fastening solution engineered for industrial applications requiring durability and reliability through thousands of opening and closing cycles. This black woven nylon loop fastener features a high-performance acrylic-based pressure-sensitive adhesive that delivers excellent shear strength, chemical resistance, and solvent resistance while bonding reliably to a variety of substrates including high surface energy metals and low surface energy plastics such as polycarbonate, acrylic, ABS, and polystyrene. The fastener is pre-shrunk to ensure stability and flatness, making it an ideal alternative to traditional closure methods like zippers, screws, snaps, and hooks.
Designed for both indoor and outdoor applications, the 3M Loop Fastener SJ3571 excels in marine and specialty vehicle environments where temperature fluctuations and moisture exposure are common concerns. The fastener maintains excellent temperature resistance up to 200°F (93°C) and offers superior UV stability and moisture resistance. With its soft, pliable napped loop backing covered with thousands of tiny loops, this product provides consistent engagement with 3M Hook Fasteners for up to 5000 closure cycles. The pressure-sensitive adhesive technology eliminates the need for sewing, solvent activation, or bulk adhesive bonding, allowing for both manual and automatic application using standard equipment.
This industrial-grade fastening system is supplied in convenient 4-roll cases, with each roll measuring 3/4 inch wide by 50 yards long, featuring a 4 mil polyolefin film liner with embossed 3M branding. Commonly paired with 3M Hook Fastener SJ3572, the SJ3571 loop fastener delivers exceptional versatility for securing fabric to furniture cushions, point-of-purchase displays, signage, general industrial applications, and specialty vehicle components. The breathable nylon backing ensures compatibility with various substrates while maintaining consistent performance across diverse industrial and commercial applications.
