Flamemaster Chemseal CS3204 B-1/2 Fuel Tank Sealant - Quart Kit

Flamemaster Chemseal CS 3204 B-1/2 is a standard-density, two-part polysulfide sealant for aerospace fuel tank and fuselage sealing work. The B-1/2 grade is a thixotropic, low-sag material designed for application by extrusion gun or spatula.

When cured, CS 3204 Class B provides flexibility and resistance to fuel, water and other aerospace fluids. It is typically used for sealing and repair of integral fuel tanks, cabin-pressure sealing, aerodynamic smoothing, and joints or seams in fuel and non-fuel areas.
