Material Notes:

3M Aerospace Sealant AC-730 Class C are two-part, manganese-cured, non-chromate corrosion inhabiting sealants. These Sealants provide an effective barrier against the common causes of corrosion on aluminum and between dissimilar metals. 3M AC-730 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, fay surface grade material, easily applied by spatula, brush, roller or extrusion gun. They maintain flexibility and bond strength on most metal substrates under extremes of temperature, weathering stress.Information provided by 3M
