This low-density sealant is designed for aircraft fuel tanks and fuselage applications, offering significant weight savings compared to traditional options. It features excellent elastomeric properties, strong adhesion to common substrates, and resistance to aircraft fuels and limited hydraulic fluid contact. The thixotropic paste can be applied easily and cures at room tempera

Overview
PR-1782 Class B is a low density, aircraft fuel tank and general-purpose sealant. This material is designed for fillet sealing and other aircraft fuselage sealing applications. It offers as much as a thirty percent weight savings, per unit volume, over traditional sealants used for these 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-1782 Class B is a two-part, manganese dioxide cured polysulfide sealant. 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.
