PPG Aerospace/PRC DeSoto® Liquid Black Fuel Tank Sealant PR1440A2-654

PR-1440 Class is an aircraft integral fuel tank sealant. It has service temperature range from -65 to 250 deg F, with this intermittent excursions up to 275 deg F. This material is designed for brush sealing of fasteners in fuel tanks and other aircraft fuselage sealing applications. The cured sealant maintains excellent elastomeric properties after prolonged exposure to both jet fuel and aviation gas. PR-1440 Class A is a two-part, manganese dioxide cured polysulfide compound. The uncured material is suitable for application by brush in thickness up to 25 mil. It cures at room temperature to form a resilient sealant having excellent adhesion to common aircraft substrates.
