This paper details the efforts in developing an accelerator for a qualified SR 71 fuel tank sealant system. The previously supplied accelerator was prepared with an intermediate chemical, ethyleneimine. Lockheed Martin Skunk Works (LMSW) was informed that ethyleneimine was declared by the FDA to be carcinogenic. The developed subject accelerator utilized propyleneimine that has not been declared to be carcinogenic. The efforts include the synthesis of the substrate portion of the accelerator molecule in addition to the synthesis routes to produce the final product utilizing propyleneimine. The synthesis of the accelerator utilizing propyleneimine was performed with the assistance of commercial sources. The efforts concerning the synthesis of a simplified structure of the substrate portion of the molecule was performed at LMSW laboratories. This paper details the characterization and subsequent qualification testing of the fuel tank sealant system when utilizing the developed accelerator as supplied from the commercial source.
