PR-2007 Class B is a low-density (specific gravity 1.1), fast-curing, high-temperature integral fuel tank sealant for fillet sealing of fuel tanks and other fuselage sealing applications, offering up to 30% weight saving per unit volume over traditional sealants. It is a two-part, manganese dioxide cured liquid polysulfide compound; the uncured material is a low-sag, thixotropic paste for extrusion gun or spatula application.
