To ensure stability and flatness, both the hook and the corresponding loop are preshrunk. Recommended Applications Point of purchase display and signage General industrial applications Marine and specialty vehicle applications Plasticizer Resistant Acrylic Adhesive The backing of 3M™ Plasticizer Resistant Loop Fastener SJ3523 is coated with a plasticizer resistant acrylic-based pressure sensitive adhesive. This adhesive strength builds up over time allowing for some repositionability before achieving full bond strength. The adhesive is designed specifically for use with flexible vinyls and will resist many plasticizers. It boasts good temperature and moisture resistance as well as UV stability and great shear strength. 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.
