PR1440A1 / 2 is an aircraft integral fuel tank sealant. It has a service temperature range from -65 ° F (-54 ° C) to 250 ° F (121 ° C), and intermittent excursions up to 275 °F (135 °C). This material is designed for brush sealing fasteners in fuel tanks and other airframe sealing applications. The cured sealant retains excellent elastomeric properties after prolonged exposure to both jet fuel and aviation gasoline (avgas).
