3M Aerospace AC-350 Class B-2 Fuel Tank & Fuselage Sealant

Seal and repair aircraft integral fuel tanks and fuselages with the use of 3M Aerospace AC-350 Class B-2 fuel tank and fuselage sealant from SkyGeek. The formula of this fast-curing fuel tank sealant features intermediate density and is manganese dioxide-cured. A two-component, solvent-free compound forms a thixotropic paste with excellent tooling properties to make up this aerospace sealant. Once the paste has been cured, it provides excellent resistance to aviation gasoline, jet fuel and other common aviation chemicals.
