Abstract: A high performance composite pyrotechnic product without lead in its composition, and that can be obtained on an industrial scale without encountering a problem of potlife for the intermediate paste, the product containing organic energetic charges and a combustion catalyst in a plasticized binder including a cured energetic polymer and at least one energetic plasticizer. In characteristic manner, the cured energetic polymer consists of a glycidyle azide polymer (GAP) having number average molecular weight (Mn) lying in the range 700 g/mol to 3000 g/mol, cured via its hydroxyl terminal functions with at least one curing agent of polyisocyanate type; and the combustion catalyst consists of bismuth citrate.
