Professional reclosable hook fastener with medium tack adhesive, 5000 closure cycles, woven nylon construction, 0.75 inch width, 50 yard length, 4 rolls per case for industrial applications.
The 3M™ Hook Fastener SJ3532N is a professional-grade reclosable fastening solution designed for industrial and occupational applications requiring thousands of reliable opening and closing cycles. This premium hook fastener features a woven nylon construction with approximately 300 J-shaped hooks per square inch, providing exceptional design flexibility and rapid product assembly capabilities. 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 wide variety of substrates including plastics, fabrics, and industrial materials.
When paired with 3M™ Loop Fastener SJ3533N, this hook fastener creates a durable two-part fastening system capable of withstanding up to 5,000 closure cycles while maintaining consistent performance. The 3 mil polyethylene film liner ensures stability and flatness, with preshrunk hook and loop components preventing product warping or shifting. The adhesive backing eliminates the need for sewing, solvent activation, or bulk adhesive bonding, allowing for manual or automatic application using standard equipment.
Ideal for securing fabric to furniture cushions, point-of-purchase displays, signage applications, and general indoor industrial use, this fastener offers superior durability compared to traditional alternatives like zippers, screws, snaps, and hooks. With a maximum operating temperature of 100°F (38°C) and dimensions of 0.75 inches wide by 50 yards long, each case contains 4 rolls providing comprehensive coverage for medium to large-scale fastening projects. The product is manufactured to industrial standards and is intended exclusively for occupational and industrial use.
