C C PR-1750 Class B is an aircraft integral fuel tank sealant. It has a service temperature range from -65°F (-54°C) to 250°F (121°C), with intermittent excursions up to 360°F (182°C). This material is designed for fillet sealing of fuel tanks and other air-craft fuselage sealing applications. The cured sealant maintains excellent elastomeric properties after pro-longed exposure to both jet fuel and aviation gas. PR-1750 Class B is a two-part, manganese dioxide cured polysulfide compound. The uncured material is a low sag, thixotropic paste suitable for application by extrusion gun or spatula. It cures at room tempera-ture to form a resilient sealant having excellent adhe-sion to common aircraft substrates.
