Premium woven nylon loop fastener with high-performance acrylic adhesive, rated for 5,000 closure cycles, suitable for industrial applications including marine and specialty vehicles.
The 3M™ Loop Fastener SJ3571 is a premium reclosable fastening solution designed for industrial and occupational applications requiring thousands of reliable openings and closures. This woven nylon loop fastener features a high-performance acrylic-based pressure-sensitive adhesive that delivers exceptional durability and performance across diverse substrates. The product comes in a convenient 2-roll case with each roll measuring 2 inches wide by 50 yards long, making it ideal for large-scale production and assembly operations.
This loop fastener is engineered to work seamlessly with 3M™ Hook Fasteners, particularly the SJ3572 model, creating a complete two-part fastening system that provides superior holding power compared to traditional closures like zippers, screws, and snaps. The woven nylon backing is covered with thousands of soft, pliable napped loops that enable smooth engagement and disengagement cycles. With excellent temperature resistance up to 200°F (93°C), this fastener performs reliably in both indoor and outdoor environments, making it suitable for marine applications, specialty vehicles, and demanding industrial settings.
The high-performance acrylic adhesive offers outstanding shear strength, chemical and solvent resistance, and excellent UV stability. It bonds effectively to a wide variety of substrates including metals, polycarbonate, acrylic, ABS, polystyrene, and nylon. The pressure-sensitive adhesive technology eliminates the need for sewing, solvent activation, or bulk adhesive bonding, allowing for quick manual or automated application. With a closure life rating of 5,000 cycles and preshrunk construction for stability and flatness, this product delivers consistent performance throughout its service life.
