3M AC-350 Class C-8(24) Aerospace Sealant
Categories:	Polymer; Thermoset; Polysulfide Sealant/Adhesive
Material Notes:	3M Aerospace Sealant AC-350 Class C are fast-cure, intermediate density polysulfide sealant suitable fro fuel tank and fuselage applications. These two-component, manganese dioxide cured sealant have resistance to aviation gasoline and jet fuel, as well as resistance to chemicals and petroleum products common to other aircraft industry. 3M AC-350 Class C 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 flowable, faying surface grade material easily applied by brush, roller, spatula, or extrusion gun. The sealant exhibits good tooling properties. Information provided by 3M
