Form This specification covers polysulfide (T) rubber sealing compounds containing only non-chromated corrosion inhibitors@ supplied as a two component system which cures at room temperature. Application This product has been used typically for contact with air pressures@ fuels and water@ but usage is not limited to such applications. Each application should be considered separately. Polysulfide (T) rubber has a service temperature range of -65 to + 250 ??(-54 to + 121 ??@ with short term recurring exposures (approximately 6 hours) to 360 ??(182 ??. It can be used for aerodynamic smoothing@ cabin pressure and fillet sealing and fastener overcoating.
