Constructed from woven nylon with a synthetic rubber-based adhesive backing, it is engineered to meet the F.A.R. 25.853 paragraph (a)(1)(i) 60-second vertical burn test standard. The hook side mates with the 3M SJ3518FR loop fastener to form a secure, reclosable bond. Licensed HVAC, aerospace, and industrial maintenance technicians install this fastener in applications where flame resistance is a code or regulatory requirement. The rubber adhesive delivers reliable high-temperature performance across a broad range of substrate types.\u003c\/p\u003e\u003cp\u003eThis fastener is suited for use in aerospace interiors, commercial HVAC equipment enclosures, electrical panel applications, and any installation environment that demands a flame resistant reclosable attachment solution. It bonds effectively to paper, cardboard, painted and bare metal, glass, sealed wood, and many rigid plastics. The roll format allows field cutting to length, making it practical for both large installation runs and smaller repair or retrofit work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMeets F.A.R. 25.853 paragraph (a)(1)(i) 60-second vertical burn test for flame resistance\u003c\/li\u003e\n\u003cli\u003eWoven nylon hook construction for durable, repeated open-and-close cycles\u003c\/li\u003e\n\u003cli\u003eFlame resistant synthetic rubber adhesive for high-temperature performance\u003c\/li\u003e\n\u003cli\u003eMates with 3M SJ3518FR loop fastener for a complete reclosable system\u003c\/li\u003e\n\u003cli\u003eAdheres to metal, glass, painted surfaces, sealed wood, and many plastics\u003c\/li\u003e\n\u003cli\u003e50-yard roll length minimizes splices on longer installation runs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned to mate with the 3M SJ3518FR flame resistant loop fastener as part of a reclosable hook-and-loop fastening system.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSurface preparation is critical before application — clean the substrate thoroughly to remove dust, oil, and moisture to ensure full adhesive contact. Apply firm pressure along the full length of the fastener strip after placement to activate the adhesive bond. Allow adequate dwell time before loading the joint.
