Product Description
Meets AMS-3284, TY I
CS3330 is used as an access door sealant for integral fuel tanks and pressurized cabins, as a strippable fillet, ans as a gasket for removable parts.
CS3330 is a two-part, polysulfide compound designed to seal access areas where easy separation of joint surfaces is required. CS3330 cures by a chemical reaction at room temperatures to a firm, flexible rubber. Cured CS3330 has low adhesion and forms a fuel resistant gasket that molds itself to fill all irregularities between two sufaces. Mixed, CS3330 is a pink 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.
Surface Preparation
To obtain uniform adhesion, remove all traces of oil, wax, grease, dirt, and other contamination. This is done by wiping with a clean oil free solvent.
Mixing Instructions
To 100 parts by weight of Part A add 10 parts by weight of Part B. Mix to uniform consistency.
Application
CS3330 may be applied with a pressure gun or a spatula within the specified application life. Specified applications lives are based on the standard condition of 77F and 50% relative humidity. Higher temperatures will reduce the application life. Lower temperatures will extend application life.
