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 maintains its flexibility and bond strength on most metal substrates like aluminium, stainless steel, steel, titanium, composite and many coatings under extremes of temperature, weathering and stress. 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 of MC-780 C means that it is easily squeezed from interfaying surfaces during the assembly process. MC-780 C has a unique „self-filleting“ characteristic. NAFTOSEAL® MC-780 Class C can be mixed by MCI-Mixer (Techkits as well as Semkits) 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).
