Professional-grade reclosable hook fastener with woven nylon construction, medium tack rubber adhesive, and proven durability for 5,000+ closure cycles. Ideal for industrial fastening applications including furniture, displays, and signage.
The 3M™ Hook Fastener SJ3532N is a professional-grade reclosable fastening solution designed for industrial and commercial applications requiring thousands of reliable openings and closures. This hook fastener features a woven nylon construction with approximately 300 flexible J-shaped hooks per square inch, engineered to provide exceptional design flexibility and rapid product assembly. The fastener is backed with a medium tack rubber-based pressure sensitive adhesive that delivers fast tack, excellent shear strength, and reliable bonding to a variety of substrates including plastics, making it an ideal alternative to traditional zippers, screws, snaps, and hooks.
The SJ3532N comes with a 3 mil (0.08 mm) polyethylene film liner and is optimized for indoor use with excellent temperature resistance up to 120°F (49°C). When paired with 3M™ Loop Fastener SJ3533N, this hook fastener system provides proven durability for up to 5,000 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. Both hook and loop components are preshrunk to ensure optimal stability and flatness throughout the product lifecycle.
This industrial-grade fastener is ideal for securing fabric to furniture cushions, point of purchase displays, signage applications, and general indoor industrial uses. The 2-inch width by 50-yard length configuration provides substantial coverage per roll, with 2 rolls included per case for convenient bulk purchasing. Designed exclusively for industrial and occupational use, this product meets professional standards for durability, reliability, and performance in demanding commercial environments.
