CS 3213 is a corrosion Inhibitive fuel-resistant sealant, manganese oxide cured containing 5% soluble chromate for use on integral fuel tanks and pressurized cabins as well as other areas subject to contact with aircraft fuels, lubricants, oils, water and/or weathering. CS 3213 is a two-part polysulfide base compound which cures at room temperature to a flexible, resilient rubber with excellent adhesion to aluminum, magnesium, titanium, steel and numerous other materials. CS 3213 is designed to withstand the attack of sulfur compounds that are present in jet fuels. When mixed, CS 3213 Type A is a self-leveling liquid. CS 3213 Type B is a thixotropic paste that will not flow or sag on vertical or overhead surfaces. CS 3213 Type C materials are intended for the sealing of faying surfaces.
