    Naftoseal® MC-780 Class B is a two-component, manganese-dioxide cured polysulfide polymer system with low density providing excellent fuel tank and fuselage seals. It has outstanding resistance to aviation gasoline and jet fuel, as well as resistance to the chemicals and petroleum products used in the aircraft industry. Additionally, it was developed for a service temperature between -55 °C (-67 °F) to +130 °C (+ 266 °F) and withstand a short-term temperature of +182 °C (+360 °F). Naftoseal® MC-780 Class B maintains its flexibility and bond strength on most metal substrates like aluminum, stainless steel, steel, titanium, composite and many coatings under extremes of temperature, weathering and stress. The mixed compound is a thixotropic paste easily applied by extrusion, injection gun or spatula. It has excellent tooling properties. Naftoseal® MC-780 Class B can be mixed by MCI-Mixer or by appropriate 2-component mixing and dosing systems. The curing time may be reduced considerably by increasing the temperature (up to 60 °C or 140 °F max).
