Professional black hook fastener with 300 hooks per square inch, medium tack rubber adhesive, and 5000 closure cycles. Ideal for industrial applications requiring durable, reusable fastening solutions.
The 3M™ Hook Fastener SJ3532N is a professional-grade reclosable fastening solution designed for industrial and occupational applications requiring thousands of secure openings and closures. This black hook fastener features flexible J-shaped hooks with approximately 300 hooks per square inch, backed by a medium tack rubber-based pressure sensitive adhesive that delivers fast tack and excellent shear strength. The woven nylon construction provides superior design flexibility and enables rapid product assembly, making it an ideal alternative to traditional closures such as zippers, screws, snaps, and hooks.
When paired with 3M™ Loop Fasteners, particularly the SJ3533N model, this hook fastener system provides exceptional durability and reliability for demanding applications. The medium tack rubber adhesive bonds quickly to a variety of substrates including plastics, fabrics, and other materials, with a 3 mil polyethylene film liner ensuring stability and flatness. This fastener is engineered for indoor general industrial applications with a maximum operating temperature of 100°F (38°C), offering reliable performance across construction, electronics, furniture, medical, and transportation industries.
The product comes in convenient roll format with 2 rolls per case, each roll measuring 1.5 inches in width and 50 yards in length. With a closure life of 5000 cycles, this fastener solution eliminates the need for sewing, solvent activation, or complex bonding processes, instead utilizing pressure sensitive adhesive technology that can be applied manually or automatically using standard equipment. The engaged thickness of 0.15 inches ensures proper meshing with corresponding loop fasteners while maintaining a clean, professional appearance.
