PPG Aerospace® PR-1422 B-2 Brown DMS 2082E Type 1, Grade 1 & 2 Class B-2 Spec Fuel Tank Sealant - 6 oz 654-SemKit

PR-1422 Class B is an integral fuel tank sealant for aircraft. It has a service temperature range of -65°F (-54°C) to 250°F (121°C) and intermittent exposures up to 275°F (135°C). This material is formulated for fillet sealing of fuel tanks and for other applications sealing an aircraft fuselage. The cured sealant has good elastomeric properties after prolonged exposure to jet fuel and aviation gas.

PR-1422 Class B is a two-part, dichromate cured poly-sulfide formulation. The uncured material is a low sag, thixotropic paste suitable for application by either extrusion gun or spatula. It cures at room temperature to provide a resilient sealant which has excellent adhesion to typical aircraft substrates.
