Material Notes:
3M Aerospace Sealant AC-360 Class B are fast cure, intermediate density two-component, manganese dioxide cure, polysulfide fuel tank and fuselage sealant. 3M AC-360 Class B Sealants have outstanding resistance to aviation gasoline and jet fuel, as well as resistance to chemicals and petroleum products common to the aircraft industry. 3M AC-360 Class B 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 thixotropic paste easily applied by extrusion, injection gun or spatula. It has excellent tooling properties.Information provided by 3M
