PS890 is used in aircraft as a sealant for integral fuel tanks. A two-part, manganese-cured polysulfide compound, PS890 cures at room temperature. PS890 forms a flexible sealant having superb adhesion to most common aircraft surfaces. It shows excellent resistance to synthetic lubricating oils, petroleum-based hydraulic fluids, water and alcohols. PS890 gives outstanding protection against corrosion caused by the galvanic bonding of different metals. The compound and accelerator should only be mixed when ready to use.
