  • Bonding agents for HTPB-type solid propellants
    Patent number: 5417895
    Abstract: Solid composite propellants are prepared by combining solid fuel and oxidizer particles, hydroxy-terminated prepolymers, and bonding agents which have polar functional groups to bond to the oxidizer particles and hydroxyl groups converted to isocyanate groups to bond to the binder. These bonding agents replace the non-reacted precursors as well as aziridine-type bonding agents in common use.
