3M™ Hook Fastener SJ3532N, Black, 4 in x 50 yd, 1 Roll/Case

3M™ Hook Fastener SJ3532N is a rubber-based hook fastener that outperforms other fasteners with its 3 mil (0.08 mm) polyethylene film liner. It can be used as an alternative to various closures such as zippers, screws, snaps, hooks, and more. The fastener has flexible J-shaped hooks, with approximately 300 hooks per square inch (46 hooks/square cm.), that protrude from a woven backing. It is commonly paired with 3M™ Loop Fastener SJ3533N and can also engage with other 3M™ Loop Fasteners. Both the hook and the corresponding loop are preshrunk to ensure stability and flatness.

The backing of 3M™ Hook Fastener SJ3532N is coated with a medium tack rubber-based pressure-sensitive adhesive. This adhesive bonds quickly to your substrate when pressure is applied. It has quick stick, short dwell time, and good shear strength. The adhesive is designed for indoor applications and can be applied to many substrates, including plastics.

3M™ Hook and Loop Fasteners offer design flexibility, fast product assembly, smooth and clean exterior surfaces, and excellent product performance in many applications. The fasteners consist of hooks and loops that engage to form a quick fastening attachment. To disengage the attachment, simply pull the strips apart by hand. The use of a pressure-sensitive adhesive reduces or eliminates the need for sewing, solvent activation, dielectric or ultrasonic bonding, or bulk adhesive bonding. Pressure-sensitive adhesive products can be applied manually or automatically using a variety of equipment choices.

3M™ Hook and Loop Fasteners provide strong and tough attachment solutions. Simply press together, and the tiny, stiff hooks mesh with pliable loops to create a quick and secure fastening system. Backed with a variety of 3M adhesive technologies, you can easily meet application demands that require thousands of easy opening and closings.
