PPG Aerospace® PR-1440 B-2 Fuel Tank Sealant from SkyGeek offers lightweight and flexible performance. Formulated specifically for use in the aircraft's fuel tank, the sealant is resistant to all types of aviation gasoline and jet fuels. The thixotropic paste is easy to apply and is suitable for use on vertical surfaces. Use PPG Aerospace® PR-1440 B-2 Fuel Tank Sealant to seal cracks, gaps and other imperfections, ensuring the fuel tank is leak-free and flight-ready. PPG Aerospace® PR-1440 B-2 Fuel Tank Sealant is gray and blends in beautifully with the fuel tank for a seamless finish. The Type 2, Class B-2 sealant is sold in a 2.5-ounce 655-SemKit for easy application.
PPG Aerospace® PR-1440 B-2 Fuel Tank Sealant from SkyGeek is ready to perform, even in challenging conditions. The sealant offers a wide service temperature range from -65ºC (-54ºC) to 250ºF (121ºC) and can withstand brief exposure to temperatures up to 275ºF (135ºC) without failing. The sealant is most commonly used for fillet sealing of fuel tanks, but is also suitable for other sealing applications in areas where exposure to aircraft fuels is likely. PPG Aerospace® PR-1440 B-2 Fuel Tank Sealant cures at room temperature for convenience.

Note: The application and performance property values above are typical for the material, but not intended for use in specifications or for acceptance inspection criteria because of variations in testing methods, conditions and configurations.
Surface preparationImmediately before applying sealant to primed substrates, the surfaces should be cleaned with solvents. Contaminants such as dirt, grease, and/or processing lubricants must be removed prior to sealant application.
A progressive cleaning procedure should be employed using the appropriate solvents and new lint free cloth (reclaimed solvents or tissue paper should not be used). Always pour solvent on the cloth to avoid contaminating the solvent supply. Wash one small area at a time.
It is important that the surface is dried with a second clean cloth prior to the solvent evaporating to prevent the redeposition of contaminants on the substrate. Substrate composition can vary greatly. This can affect sealant adhesion. It is recommended that adhesion characteristics to a specific substrate be determined prior to application on production parts or assemblies.
For a more thorough discussion of proper surface preparation, please consult the SAE Aerospace Information Report AIR 4069. This document is available through SAE, 400 Commonwealth Avenue, Warrendale, PA 15096-0001.
