NAFTOSEAL MC-780 CLASS B-1/2 LIGHTWEIGHT FUEL TANK & FUSELAGE SEALANT 130ML TECHKIT

Naftoseal MC-780 Class B-1/2 Lightweight Fuel Tank & Fuselage Sealant in the 130 ml Techkit is a two-part polysulfide system engineered for rapid application and long-term integrity in fuel-wet and pressurized structures. Its low-density formulation helps reduce overall airframe mass while maintaining strong adhesion to aluminum, titanium, composites, and coated surfaces. The short work life supports precise sealing in production or maintenance environments, forming flexible, solvent- and fuel-resistant joints that withstand temperature cycling and vibration. Ideal for access panels, integral tanks, structural joints, and repair tasks, it delivers consistent performance under demanding operational and environmental conditions.
