(R) Sealing Compound, Polysulfide (T) Rubber, Fuel Resistant, Non-Chromated Corrosion Inhibiting For Intermittent Use to 360 °F (182 °C)
|Publication Date:||1 December 2015|
This specification covers polysulfide rubber sealing compounds containing only non-chromated corrosion inhibitors, supplied as a two component system which cures at room temperature.
This product has been used typically in applications requiring contact with air pressure, fuel and water, and for fillets, fastener seals, and faying surface seals as well as initial sealing of faying surfaces, overcoating of fasteners, and sealing of seams and joints but usage is not limited to such applications. Polysulfide 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).
AMS3100 adhesion promoter should be applied prior to the sealant unless otherwise specified by the manufacturer.
Sealing compounds covered by this specification are classified as follows:
