It offers as much as a thirty percent weight savings, per unit volume, over traditional sealants used for similar purposes. The cured sealant maintains excellent elastomeric properties after prolonged exposure to aircraft fuels both jet fuel and aviation gas, and will resist limited contact to diphosphate ester based hydraulic fluids.
PR-2007 Class B is a two-part, manganese dioxide cured liquid polysulfide polymer compound. The uncured material is a low sag, thixotropic paste suitable for application by extrusion gun or spatula. It cures at room temperature to form a resilient sealant having excellent adhesion to common aircraft substrates.
