Sealing Compound, Polysulfide (T) Synthetic Rubber For Integral Fuel Tank and Fuel Cell Cavities Low Density (1.20 to 1.35 sp gr), for Intermittent Use to 360°F (182°C)
This specification covers three classes of fuel-resistant polysulfide (T) sealing compound with low specific gravity, supplied as a two-component system which cures at room temperature.<p>This sealing compound has been used typically in sealing aircraft integral fuel tanks, fuel tank fillets and faying surfaces, pressure barriers and moldline surfaces, but usage is not limited to such applications. The sealing compound is resistant to jet fuels and is capable of withstanding long-term exposure from -65 to +250 degrees F (-54 to +121 degrees C) and short-term exposure (six hours) to 360 degrees F (182 degrees C).
