ABSTRACT:
Pyrotechnic compositions having a decreased susceptibility to external influences are obtained by suspending pyrotechnic particles in a dilute solution of a coating polymer and adding a second polymer which is more soluble in the solvent, so that microdroplets of the coating polymer are formed, completely enclosing the pyrotechnic particles. The coated particles are hardened by exposure to air, optionally in the presence of a hardening catalyst.
