Premium reclosable fastening solution featuring interlocking mushroom heads with 250 stem density, offering 5X stronger tensile strength than traditional hook-and-loop products with clear acrylic adhesive for multiple substrates.
The 3M™ Dual Lock™ Reclosable Fastener SJ3560 is a revolutionary alternative to traditional fastening methods such as screws, nuts, and bolts. This innovative product features clear, interlocking mushroom-shaped heads with 250 stem density per square inch, delivering up to 5X the tensile strength of typical hook-and-loop products. The fastener is engineered with a clear acrylic adhesive tape protected by a removable film liner, providing exceptional bonding performance on a wide variety of substrates including metals, glass, and plastics such as acrylics, polycarbonate, and ABS. With a roll size of 1 inch wide by 50 yards long, this product comes in a 2 roll case, making it ideal for both small and large-scale industrial applications.
Designed for durability and ease of use, the 3M Dual Lock SJ3560 requires no drilling, screwing, or sewing tools, enabling quick and efficient installation. The product features an audible snap when secure, verifying proper closure of the attachment. Its exceptional temperature resistance up to 220°F (104°C) and compatibility with indoor and outdoor environments make it suitable for diverse applications including architectural panels, graphic attachment, specialty vehicles, general industrial attachment, and toll transponders. The fastener maintains its strength throughout multiple attachments and detachments, offering up to 1000 closure cycles.
This reclosable fastener system provides outstanding design flexibility by allowing engagement with different stem densities (Type 170, Type 250, or Type 400) for varying levels of strength and system performance. The clear, translucent appearance ensures aesthetic improvements while remaining hidden beneath surfaces without interfering with material integrity. Simply peel the pieces apart by hand to disengage, making it an ideal solution for applications requiring high strength, versatility, and removable closures. The product is backed by 3M's commitment to quality and innovation in industrial adhesive and tape solutions.
