NAFTOSEAL® MC-238 Class B is a two-component, manganese-dioxide cured polysulfide polymer system 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.
NAFTOSEAL® MC-238 Class B 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.
The mixed compound is a thixotropic paste easily applied by extrusion, injection gun or spatula. It has excellent tooling properties.
NAFTOSEAL® MC-238 Class B 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).
