Access Door Sealant
CS 3330 is used as an access door sealant for integral fuel tanks and pressurized cabins, as a strippable fillet, and as a gasket for removable parts. CS 3330 is a two-part, polysulfide compound designed to seal access areas 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 thixotropic paste which is easily applied with an extrusion gun or spatula, but will not flow from vertical or overhead surfaces. The cured sealant is resistant to aircraft fuels, lubricants, oils, water, and weather and remains flexible at low temperatures.
