Product Attributes
PPG Aerospace® PRC-DeSoto P/S 890B2 Fuel Tank Sealant from SkyGeek is a two-part sealant that bonds readily to the inside of your aircraft's fuel tank or fuselage. The class C sealant has a service temperature range from -65ºF (-54ºC) to 250ºF (121ºC) and can even withstand intermittent exposure to temperatures as high as 275ºF (135ºC). The sealant is designed to be brushed and ideal for fay sealing applications. Once cured, it has excellent elastomeric properties and can easily withstand prolonged exposure to jet fuels and aviation gasoline. PPG PRC-DeSoto P/S 890B2 Fuel Tank Sealant is a two-part formula and is shipped as two pre-measured components in separate containers. The two-part manganese dioxide cured polysulfide component is a roller-grade liquid and is best applied by brush, but can also be applied via an extrusion gun or spatula. The sealant cures at room temperature and standard conditions. PPG Aerospace® PRC-DeSoto P/S 890B2 Fuel Tank Sealant adheres well to most common aircraft substrates.

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.
