Cabin Pressurization / Fuselage Sealants

3M™ Aerospace Sealant AC-665 Class B - Chromated (Corrosion Inhibitive Sealant)

AC-665 Class B is a two-part, manganese-cured, chromated, corrosion inhibiting sealant. This sealant provides an effective barrier against the common causes of corrosion on aluminum and between dissimilar metals. Ac-665 Class B has 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 thixotropic paste, easily applied by spatula, extrusion gun or injection gun. It maintains its flexibility and bond strength on most metal substrates under extremes of temperature, weathering and stress.
