This specification covers fuel-resistant, two-component polysulfide synthetic rubber compounds which cure at room temperature.
Removed Air Content, Radiographic Density, and minimum Flow requirements. Added heat conditioning prior to testing Low Temperature Flexibility panels that was a requirement in MIL-S-8802. Aligned specification to current requirements in AS5502 and AS5127/1. Changed accelerated cure requirements. Added an optional adhesion promoter requirement. Added an alternative composite material (IM7/977-3). Added additional clarifications to current requirements and made editorial corrections.
