PR-1440 Fuel Tank Sealant
Discription:
PR-1440 is is a two-part, manganese dioxide cured polysulfide 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 275°F (135°C). The cured sealant maintains excellent elastomeric properties after prolonged exposure to both jet fuel and aviation gas
Class A
PR-1440 Class A material is designed for brush sealing of fasteners in fuel tanks and other aircraft fuselage sealing applications. The uncured material is suitable for application by brush in thickness up to 25 mils. It cures at room temperature to form a resilient sealant having excellent adhesion to common aircraft substrates.
