  • MULTI-PART MIXED ENERGETIC MATERIALS AND EPOXY BINDERS
    Publication number: 20230365476
    Abstract: The present invention relates to methods and processes to prepare pre-mixed compositions that can be combined to form pyrotechnic compositions in mixed multiple parts. In exemplary embodiments, a binder curing agent ingredient is premixed with pyrotechnic fuels and can also include other pyrotechnic additives and processing aides. Other binder ingredients such as a binder resin can be premixed with the pyrotechnic oxidizers and can also include other pyrotechnic additives and processing aides. The resulting mixtures are not explosive and are much safer to handle and easier to store for extended shelf-life over a final pyrotechnic composition. Further, the pre-mixed mixtures can be stored in bulk until needed and rapidly combined to achieve the final pyrotechnic composition.

  • Three part mixing process for energetic materials and epoxy binder
    Patent number: 11746068
    Abstract: The present invention relates to methods of preparing pre-mixed compositions that can be combined to form pyrotechnic compositions. In exemplary embodiments, a binder ingredient is premixed with the pyrotechnic fuels and can also include other pyrotechnic additives and processing aides. Other binder ingredients can be premixed with the pyrotechnic oxidizers and can also include other pyrotechnic additives and processing aides. The resulting mixtures are not explosive and are therefore easier to store and much safer to handle. These pre-mixed mixtures can be stored in bulk until needed and rapidly combined to achieve final composition.
