Material Notes:

3M Aerospace Sealant AC-350 Class A are fast-cure, intermediate density two-component, manganese dioxide cure, brushable, polysulfide fuel tank and fuselage sealants. 3M AC-350 Class A Sealants have outstanding resistance to aviation gasoline a jet fuel, as well as resistance to chemicals and petroleum products common to the aircraft industry. 3M AC-350 Class A Sealants maintain flexibility and bond strength on most metal substrates such as aluminum, titanium, steel, stainless steel, and many coatings under extremes of temperature, weathering and stress. The mixed compound is a pourable liquid easily applied by brush or roller. It has excellent tooling properties.Information provided by 3M
