3 Scotchmate Reclosable Fasteners SJ3519FR and SJ3518FR Nylon Flame Resistant Hook and Loop Technical Data March, 2005 Product Description 3M Scotchmate Reclosable Fasteners offer advanced closure alternatives to zippers, screws, snaps, hooks, bolts and more. They offer greater design flexibility, faster product assembly, smoother and cleaner exterior surfaces and improved product performance in many applications. The hook and loop fasteners consist of two strips of nylon fabric which engage to form a quick fastening attachment. Simply pull the strips apart by hand to disengage. The woven hook is covered with about 300 tiny, stiff hooks, per square inch (46/sq. cm.). The woven loop is covered with thousands of soft, pliable napped loops, providing for thousands of openings and closings (cycles). The hook and loop are preshrunk to insure maximum dimensional stability and flatness. These hook and loop fasteners are coated on the backside with a unique flame resistant synthetic rubber based pressure sensitive adhesive formulated to meet the requirements of the EU Directive 2003/44/EC amending the Council Directive 76/769/EEC, TM 3M Scotchmate Reclosable Fasteners SJ3519FR and SJ3518FR Nylon Flame Resistant Hook and Loop Note: The following technical information is not product release requirements, but rather represent Typical System typical performance using standard test methods and is intended for use as a guide to assist in Performance selection of 3M Scotchmate Reclosable Fasteners for further evaluation. This technical Physical Properties information should not be used for setting standards. and Characteristics Unless stated differently, typical system performance characteristics were measured under controlled laboratory conditions of 72F (22C) and 50% Relative Humidity to obtain maximum reliability. The user should evaluate products in the actual application to ensure suitable performance for the intended use.

Fasteners may slip or creep in the direction of the static load forces at temperatures or weights greater than indicated. The user is responsible for designing the amount of fastening area based upon the specific conditions for the application. Four square inches of fastening area per pound of static load is suggested as a starting point for such evaluations. a) System performance tests are determined by measuring the performance of the entire mated reclosable fastener system (two non-anodized aluminum plates joined together with the indicated fasteners). The T peel, only has the closure performance measured per ASTM D5170 and was not adhered to aluminum panels. The 90 peel has one of the mated fasteners attached to a non-anodized aluminum plate while the other mated fastener is disengaged at a 90 angle. b) 3M Scotchmate Reclosable Fasteners SJ3518FR and SJ3519FR are engaged with firm pressure and disengaged, peeled or cleaved at the rate of 12 inches (305 mm) per minute. c) Cycle Life is the number of cycles (openings and closings) the fastener can provide while maintaining 50% or greater of the original peel values. d) Shelf life is from date of manufacture when stored in original packaging between 60 to 80F (16 to 27C) and 40 to 60% relative humidity. - 2 -
