Flamemaster CS-3201 B-1/2 Integral Fuel Tank and Cabin Sealant
Help prevent unnecessary wear and tear to your aircraft by sealing it with Flamemaster CS-3201 B-1/2 integral fuel tank and cabin sealant. This polysulfide-based compound creates an airtight seal on airplane cabins and fuel tanks to prevent leakage and provide excellent protection from harmful elements. Apply this thixotropic paste by spatula or extrusion gun, allow it to cure at room temperature and enjoy the benefits the resulting durable seal provides. Your aircraft will gain resistance to water, weathering, aviation fuel, oils and many other common aerospace chemicals. Thanks to this resistance, CS-3201 also helps protect your aircraft from corrosion.
SURFACE PREPARATIONTo obtain good adhesion, remove all traces of oil, wax, grease, dirt, or other contamination. This is done by wiping with a clean oil free solvent. Clean only small areas at one time and wipe dry with a clean cloth before the solvent evaporates. Maintain a clean solvent supply.
MIXING INSTRUCTIONSWhen mixing pre-packaged kits the entire contents of base compound (Part A) and curing agent (Part B) should be used. For small quantities mix by weight to ratio indicated in Fig. 1 Applications Properties. The lip of Part A container should be removed to facilitate mixing. Next stir Part B in its original container until it is homogeneous. Add Part B to Part A and mix thoroughly for seven to ten minutes or until uniform in color. Scrape sides and bottom of the container to assure a complete mix. CS 3201 may be mixed by hand or with a mechanical mixer. When using a mechanical mixer, use low speeds since high speeds will generate internal heat and reduce application life.
APPLICATION INSTRUCTIONSCS 3201, Class A may be applied with a brush. CS 3201, Class B may be applied with a pressure gun or a spatula. Specified application lives are based on the standard conditions of 77 deg. F and 50% relative humidity. Higher humidity will reduce the application life. Lower temperatures or lower humidity will extend the application life. For every 10 deg. F rise the application is reduced by one half, for every 10 deg. F drop, it is doubled.
CUREThe cure period is dependent on the application life, temperature, and relative humidity. Increased temperature and increased relative humidity will speed cure. Reduced temperature and reduced relative humidity will slow cure. Cure may be accelerated by heating up to 120 deg. F. Material should be firm rubber in 3 hours.
