|Publication Date:||1 September 2020|
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 (cumulative total of approximately 6 hours) to 360 °F (182 °C). AMS3100 adhesion promoter may be applied prior to application of the sealant in accordance with recommendations from the sealant manufacturer for specific substrates.
Sealing compounds covered by this specification are classified as follows:
Class A - Suitable for application by brush. Available with the following application times in hours:
Class B - Suitable for application by extrusion gun or spatula. Available with the following application times in hours:
Class C - Suitable for application by brush, extrusion gun, roller or spatula. Available with the following application times in hours:
Notation: ( ) Assembly time in hours.
