This specification covers a polysulfide (T) rubber sealing compound with non-chromated corrosion inhibitors, supplied as a two component system which cures at room temperature. 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 °F (-54 to +121 °C), with short term recurring exposures (approximately 6 hours) to 360 °F (182 °C). It can be used for aerodynamic smoothing, cabin pressure and fillet sealing and fastener overcoating.
