Product Information
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 shortterm temperature of +182 °C (+360 °F).
Naftoseal MC-780 Class A 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 pourable, slightly thixotropic paste easily applied by extrusion, injection gun, spatula or brush and has excellent tooling properties.
The curing time may be reduced considerably by increasing the temperature (up to 60 °C / 140 °F max).
