Flamemaster Chemseal CS 3204 Class B-1/2 is a standard-density, two-part manganese-dioxide-cured polysulfide sealant for fuel tank and fuselage sealing work. The thixotropic Class B material is intended for application by extrusion gun or spatula and cures at room temperature to a flexible, resilient dark-grey sealant.

CS 3204 is used for sealing and repair of integral fuel tanks, pressure-cabin sealing, aerodynamic smoothing, and joints or seams in fuel and non-fuel areas. The cured material offers resistance to fuel, water, and other aerospace fluids.
