SAE AMS3269C

This document has been declared "Stabilized" and will no longer be subjected to periodic reviews for currency. Users are responsible for verifying references and continued suitability or technical requirements. New technology may exist.

This specification covers three class of fuel-resistant polysulfide (T) sealing compound with high strength and temperature characteristics, supplied as a two-component system which cures at room temperature.

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 \mDF (-54 to 121 \mDC) and short-term exposure (approximately 6 hours) to 360 \mDF (182 \mDC).
