Professional black woven nylon loop fastener with rubber-based adhesive for industrial applications. Provides 5000+ reusable cycles, bonds to multiple substrates, and offers fast assembly without sewing or solvent activation.
The 3M™ Loop Fastener SJ3533N is a professional-grade reclosable fastening solution designed for industrial and occupational applications. This black woven nylon loop fastener is engineered to work seamlessly with 3M™ Hook Fasteners, providing exceptional durability for thousands of opening and closing cycles. Each case contains 3 rolls of 1-inch wide by 50-yard long fastener material, making it ideal for large-scale manufacturing and assembly operations.
This fastener features a medium tack rubber-based pressure sensitive adhesive backing that delivers fast tack, excellent shear strength, and reliable bonding to a variety of substrates including plastics, fabrics, and other industrial materials. The woven loop construction is covered with thousands of soft, pliable napped loops that engage securely with corresponding hook fasteners. The preshrunk design of both hook and loop components ensures stability and flatness throughout the product lifecycle, maintaining consistent performance across repeated use cycles.
Ideal for applications such as securing fabric to furniture cushions, point of purchase displays, signage, and general indoor industrial applications, the SJ3533N offers a superior alternative to traditional closures like zippers, screws, snaps, and hooks. With a maximum operating temperature of 100°F (38°C) and excellent temperature resistance of 120°F (49°C), this fastener is best suited for indoor use where reliable, reusable attachment is critical. The pressure sensitive adhesive technology eliminates the need for sewing, solvent activation, or complex bonding methods, enabling fast manual or automatic application.
