Premium black hook fastener with rubber-based adhesive for 5000+ closures. 1.5 inch width, 50 yard roll with excellent substrate bonding and design flexibility.
The 3M™ Hook Fastener SJ3530 is a premium reclosable fastening solution designed for industrial and occupational applications requiring thousands of reliable openings and closures. This black hook fastener features a woven nylon construction with approximately 300 hooks per square inch, providing exceptional design flexibility and rapid product assembly. The fastener is backed with a high-tack rubber-based pressure-sensitive adhesive that delivers fast initial tack, excellent shear strength, and reliable bonding to a wide variety of substrates including plastics such as polyethylene and polypropylene.
When paired with the 3M™ Loop Fastener SJ3531, this hook fastener system provides durability for up to 5000 opening and closing cycles, making it an ideal alternative to traditional closures like zippers, screws, snaps, and hooks. The product comes in a convenient 50-yard roll format with 2 rolls per case, featuring a 3-mil polyethylene film liner for optimal performance. The preshrunk hooks and corresponding loops ensure stability and flatness throughout the product lifecycle, while the flexible J-shaped hook design allows for smooth engagement and disengagement.
This industrial-grade fastener is specifically engineered for indoor applications with a maximum operating temperature of 90°F (32°C) and is commonly used for securing fabric to furniture cushions, point of purchase displays, signage, and general industrial applications. The pressure-sensitive adhesive technology eliminates the need for sewing, solvent activation, or complex bonding methods, allowing for both manual and automatic application using standard equipment.
