This material is designed for fillet sealing and other aircraft fuselage sealing applications and offers as much as a thrity 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.
PR1782 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.
