Patco D9100 Flame Retardant Aircraft Waterseal Tape | FR Corrosion Inhibitor | BMS 8-346 | FAR 25.853(a)

The aerospace industry's trusted waterseal and corrosion inhibitor tape — flame retardant, transparent, and engineered for aircraft wet areas, high-wear surfaces, and moisture-critical applications. Approved by Boeing, Airbus, Fokker, and the FAA for use aboard commercial aircraft worldwide. Patco D9100 is a flame retardant polyurethane waterseal tape designed for floor joint sealing on aircraft decking in all wet areas — including entryways, galleys, and lavatories. Its urethane-based adhesive bonds directly over wet sealant, making it ideal for MRO operations and routine aircraft refurbishment where moisture protection and corrosion inhibition are critical.
