High Performance Rubber Adhesive
The backing of 3M™ Hook Fastener SJ3526N is coated with a high performance rubber-based pressure sensitive adhesive. This tacky adhesive bonds quickly to your substrate when pressure is applied. It features quick stick, short dwell time and very good shear strength. This adhesive is designed to function with indoor applications and is suited for application to many substrates, including plastics.
Secure, Repeated Closures
3M™ Hook and Loop Fasteners offer great design flexibility, fast product assembly, smooth and clean exterior surfaces and excellent product performance in many applications. 3M Hook and Loop Fasteners consist of hooks and loops which 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.
Bringing it All Together
3M™ Hook and Loop Fasteners provide the strong, tough attachment solutions you need. Simply press together and the tiny, stiff hooks mesh with pliable loops to create a quick, 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.
