Professional black hook fastener with high-tack adhesive, 4 inches wide by 50 yards long. Delivers 5000 closure cycles with superior durability for industrial applications. Compatible with 3M Loop Fasteners for flexible, reusable fastening solutions.
The 3M™ Hook Fastener SJ3530 is a professional-grade reclosable fastening solution designed for industrial and occupational applications. This black hook fastener features a woven nylon construction with approximately 300 hooks per square inch, engineered to work seamlessly with 3M™ Loop Fasteners for thousands of reliable openings and closures. The fastener comes in a convenient 4-inch width by 50-yard length roll format, making it ideal for high-volume production environments and custom applications requiring flexible attachment solutions.
Backed with a high-tack rubber-based pressure-sensitive adhesive, the SJ3530 delivers exceptional bonding performance with fast tack, excellent shear strength, and reliable adhesion to a variety of substrates including plastics like polyethylene and polypropylene. The 3-mil polyethylene film liner ensures stability and flatness, while the preshrunk hook and loop construction maintains dimensional consistency throughout the product lifecycle. This fastener provides an excellent alternative to traditional closure methods such as zippers, screws, snaps, and hooks, offering superior design flexibility and faster product assembly times.
Designed for indoor general industrial applications, the SJ3530 is particularly well-suited for securing fabric to furniture cushions, point-of-purchase displays, and signage. With a maximum operating temperature of 90°F (32°C) and a proven closure life of 5000 cycles, this fastener delivers consistent performance in demanding industrial environments. 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.
