3M AC-665 Class C-48 Aerospace Sealant
Categories: Polymer; Thermoset

Material Notes: 3M Aerospace Sealant AC-665 Class C are two-part, manganese-cured, chromate containing, corrosion inhabiting sealants. These Sealants provide an effective barrier against the common causes of corrosion on aluminum and between dissimilar metals. 3M AC-665 Class C Sealants have outstanding resistance to aviation gasoline and jet fuel, as well as resistance to chemicals, hydraulic fluids and petroleum products common to the aircraft industry. The mixed compound is a flowable, faying surface grade material, easily applied by brush, spatula, extrusion gun or roller. They maintain flexibility and bond strength on most metal substrates under extremes of temperature, weathering stress.
