Sealing Compound, Polysulfide (T) Synthetic Rubber for Integral Fuel Tank and Fuel Cell Cavities High Strength, for Intermittent Use to 360 °F (182 °C)
|Publication Date:||1 September 2011|
This specification covers three classes of fuel-resistant polysulfide (T) sealing compound with high strength and temperature characteristics, supplied as a two-component system which cures at room temperatures.
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 -65 to 250 °F (-54 to + 121 °C), with short-term exposure (approximately 6 hours) to 360 °F (182 °C).
AMS3100 adhesion promoter should be applied prior to sealant.
Sealing compounds covered by this specification are classified by method of application and application times as follows:
Class A - Suitable for application by brushing, injecting,, or spraying. Available in the following application times in hours:
Class B - Suitable for application by extrusion gun or spatula. Available in the following application times in hours:
Class C - Suitable for extrusion gun, spatula, brush, or roller. Available in the following application times in hours:
Notation: ( ) Assembly time in hours
All supplied material must conform to both class and application time of the specific sealing compound that has been ordered.
