Flamemaster CS3330B2PT Chemseal Door Sealant-Pint

Boeing provides Flamemaster CS3330B2PT Chemseal Door Sealant-Pint. A low adhesion access door and panel sealant for integral fuel tanks and pressurized cabins, as a strippable fillet, and as a gasket for removable parts. A two-part, polysulfide compound designed to seal faying surfaces where easy separation of joint surfaces is required. CS 3330 cures by a chemical reaction at room temperature to a firm, flexible rubber. Cured CS 3330 has low adhesion and forms a fuel resistant gasket that molds itself to fill all irregularities between two surfaces. Mixed, CS 3330 is a red paste of brushable consistency. The cured sealant is resistant to aircraft fuels, lubricants, oils, water, and weather and remains flexible at low temperatures.
