FAA PMA-approved aerospace corrosion prevention tape with flame resistance for aircraft floor protection
3M Corrosion Prevention Sealing Tape 9143FR is a specialized aerospace-grade protective tape designed to safeguard aircraft interior floor systems from corrosion damage. This 43-mil thick tape provides an effective sealing layer between aircraft floor beams and floorboards, particularly in high-moisture areas such as entryways, galleys, lavatories, and cargo compartments. The tape creates a protective barrier that prevents fluids from spills and leaks from migrating into the underlying floor support system, while also preventing condensation from forming on sub-floor structures that could lead to costly corrosion damage.
The 9143FR tape features exceptional flame resistance, meeting FAA requirements per 14 CFR 25.853 (a), Appendix F, Part I (a) (1) (ii) with a 12-second vertical burn rating, making it suitable for fly-away aerospace applications. It is FAA PMA approved and listed on 3M Aerospace FAA PMA No. PQOO4414CE, Supplement No. 4, ensuring compliance with stringent aviation safety standards. The tape demonstrates excellent adhesion strength of 27 oz/in and tensile strength of 36 lb/in, providing durable protection over extended service life.
Designed with superior shop handling characteristics, the 9143FR tape can be easily cut with scissors or common shop tools and is repositionable during application, allowing technicians flexibility during installation. Upon removal after service life, the tape leaves little to no residue, making maintenance and re-application straightforward. With low-peel FR acrylic adhesive and polyester backing, this tape operates reliably across a wide temperature range from -40°F to 180°F, providing consistent performance in diverse aircraft cabin environments.
