- PR-2001LW Class B is a light weight rapid cure, low odor sealant. It has a service temperature range from -80°F (-62°C) to 320°F (160°C), with intermittent excursions up to 420°F (216°C). This material is designed for use in fillet, butt joint, and dome sealing in aircraft integral fuel tanks, fuselage and aerodynamic smoothing applications, but is not recommended for interfay sealing. The cured sealant maintains excellent elastomeric properties after prolonged exposure to both jet fuel and aviation gas.
