Flamemaster CS3205B2 Sealant Kit, Liquid, Beige, Polysulfide

NSN 8030-01-154-9256    

CS 3205 Class B aerospace sealant was designed for fuel tank and fuselage sealing applications, such as repairing integral fuel tanks, cabin pressure sealing, and aerodynamic smoothing. It can be used for sealing joints and seams in both fuel and non-fuel areas. The
dichromate curing agent is less sensitive to low humidity conditions than manganese dioxide types, so it may be preferred for dry or desert climates.

Key Features for Aviation:

• Specifically designed and qualified for demanding sealing applications in the aviation industry, particularly fuel systems.
