Professional-grade 3M Hook Fastener SJ3506 with acrylic-based adhesive, 8 inches wide by 100 yards long, designed for industrial reclosable fastening applications with excellent shear strength and temperature resistance.
The 3M™ Hook Fastener SJ3506 is a professional-grade, low-profile reclosable fastening solution designed for industrial and occupational applications. When paired with the 3M™ Loop Fastener SJ3507, this two-part fastener system provides exceptional design flexibility and enables fast product assembly in manufacturing environments. The fastener features an acrylic-based pressure sensitive adhesive backing that builds bond strength over time, allowing for initial repositionability before achieving full adhesive strength.
This hook fastener is engineered to replace traditional closure methods such as zippers, screws, snaps, and hooks in various applications. The low-profile design ensures a smooth, clean exterior surface while maintaining reliable holding power for lightweight applications. The acrylic-based adhesive offers excellent shear strength, heat resistance up to 158°F (70°C), and superior moisture resistance with outstanding UV stability. The fastener is constructed with an #83 polykraft liner featuring green print for easy identification.
The 3M Hook Fastener SJ3506 is ideal for point of purchase displays, signage, apparel closures, floor mat attachments, graphic attachments, and various mounting and trim applications across construction, electronics, furniture, medical, military, and transportation industries. This industrial-grade product delivers thousands of reliable opening and closing cycles, making it an economical solution for temporary fastening needs. 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.
