PPG Aerospace PR1422-B1/2 AMS-S-8802B1/2 Fuel Tank Sealant

PPG PR-1422 Class B sealant 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 275°F (135°C). This material is designed for fillet sealing of 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. PPG PR-1422 Class B sealant is a two-part, dichromate cured polysulfide compound. The uncured material is a low sag, thixotropic paste suitable for application by extrusion gun or spatula. It cures at room temperature to form a resilient selalant having excellent adhesion to common aircraft substrates.
