3M Aerospace Sealant AC-736 B-2 is a non-chromate corrosion inhabiting sealants, fast cure, low density two-component, manganese dioxide cure, polysulfide fuselage sealant. These Sealants act as an effective barrier against the common causes of corrosion on aluminum and between dissimilar metals. 3M AC-736 B-2 Sealants 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. 3M AC-736 B-2 Sealant maintains its flexibility and bond strength on most metal substrates such as aluminum, titanium, steel, stainless steel, and many other extremes for temperature, weathering and stress. 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 |
