PPG Aerospace® PR-1750 B-2 Gray AMS-3276E Fuel Tank Sealant - 6 oz 654-SemKit

PR-1750 Class B is an aircraft integral fuel tank sealant, offering a service temperature range from -65°F (-54°C) to 250°F (121°C) and withstanding intermittent temperatures up to 360°F (182°C). Designed for fillet sealing in fuel tanks and other fuselage sealing applications, this sealant retains excellent elastomeric properties even after extended exposure to jet fuel and aviation gas.

PR-1750 Class B is a two-part, manganese dioxide-cured polysulfide compound. In its uncured state, it is a low-sag, thixotropic paste, ideal for application by extrusion gun or spatula. It cures at room temperature to form a resilient sealant with strong adhesion to standard aircraft substrates.
