Plasticizer Resistant Acrylic Adhesive
The backing of 3M™ Plasticizer Resistant Hook Fastener SJ3522 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.
