Abstract:

This work was undertaken by the Thiokol Corporation to develop integral fuel tank sealant compounds with improved low and high temperature properties, increased toughness and adhesion, and better resistance to jet fuels. Experimental integral fuel tank sealant compounds were prepared in two-package mixes from hexamethylene dichloridetriglycol dichloride formal and pentamethylene dicMorideformal polymers. Compared to a Thiokol LP-2 base sealant, these experimental compounds displayed improved low temperature properties, equivalent toughness and adhesion to aluminum, somewhat better resistance to heat aging at 2l20F, and slightly poorer resistance to swell in aromatic fuels. Compounding studies with Thiokol LP-2 yielded formulations with improved adhesion properties and heat aging resistance. Development work on clear sealant compounds disclosed the possibility- of preparing sealants of this type from combinations 0 epoxide resins and Thiokol liquid polymers however, considerably more investigation of this aspect is required.
