CS 3330CI Class B-1/2
Access Door Sealant
2 1/2 oz. CA (2 oz.)
CS 3330CI is an access door sealant for integral fuel tanks and pressurized cabins, as a strippable fillet, and as a gasket for removable parts.
CS 3330CI is a two-part, polysulfide compound designed to seal faying surfaces where easy separation of joint surfaces is required. CS 3330CI cures by a chemical reaction at room temperature to a firm, flexible rubber. Cured CS 3330CI has low adhesion and forms a fuel resistant gasket that molds itself to fill all irregularities between two surfaces. Mixed material is a purple paste of brushable consistency. The cured sealant is resistant to aircraft fuels, lubricants, oils, water and weathering and remains flexible at low temperatures.
