3M 7010303524 Flame Resistant Hook Fastener SJ3419FR

Product Description

The 3M 7010303524 is a flame resistant, no-adhesive, woven nylon hook reclosable fastener sold as a 1.5 inches wide by 50 yard roll in black. Designated SJ3419FR, this hook component delivers an engaged thickness of 0.15 inches and is rated for continuous service up to 250 degrees F. It meets the F.A.R. 25.853 paragraph (a)(1)(i) 60-second vertical burn test requirement, making it suitable for aerospace, aviation, and flame-sensitive textile applications. The fastener is preshrunk for maximum dimensional stability and mates with the SJ3418FR loop fastener.

SJ3419FR is designed for use in applications where reclosable fastening must also meet flame resistance requirements. Typical uses include aircraft cabin interiors, protective garments, industrial fabrics, and other environments where ignition resistance is a regulatory or safety requirement. The hook fastener provides adjustable closure and is washable and dry cleanable, supporting end-use applications in apparel and soft goods. Installation or integration is performed by fabricators, aircraft interior specialists, or industrial sewers working with flame-rated textiles.
