This specification covers a polysulfide (T) rubber sealing compound with nonchromated 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 degrees F (-54 to +121 degrees C), with short term recurring exposures (approximately 6 hours) to 360 degrees F (182 degrees C). It can be used for aerodynamic smoothing, cabin pressure and fillet sealing and fastener overcoating.
AMS3265C results from a Five Year Review and update of this specification. Replacing conversion coated AMS4049 with conversion coated AMS4045 for peel test.
