ABSTRACT:
A curable binder for use in forming a castable propellant of the hydroxy-terminated polybutadiene type which uses a combination of two bonding agents, an aziridine polyester and an amine polyester. The amount of aziridine polyester is reduced by a factor of 3 to 4 compared to known systems. Improved propellant properties, including elongation at maximum load and at rupture, while maintaining comparable tensile strength and initial moduli, are obtained. A diisocyanate curing agent, an antioxidant such as di-tert-butylhydroquinone or phenyl-beta-naphthyl amine and combinations of antioxidants, and isodecyl pelargonate as a plasticizer, may be included.
