Naftoseal® MC-780 Class C is a two-component, manganese-dioxide cured polysulfide polymer system with reduced density providing excellent fuel tank and fuselage seals. It is designed for interfay surface sealing and wet riveting of fuselage components and 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 C combines low viscosity, for ease of mixing, with a high thixotropy giving good application characteristics. It can be effectively applied by extrusion, by injection gun, or by using a roller coating technique. The low viscosity means that it is easily squeezed from interfaying surfaces during the assembly process. It has a unique „self-filleting“ characteristic.
