The disclosure relates to a pyrotechnical delay charge which may be mixed in water, comprising 4-17 % by weight of boron (B) 0-17 % by weight of zirconium (Zr), titanium (Ti) and/or zirconium-nickel alloys 10-35 % by weight of titanium dioxide (TiO2) 40-65 % by weight of tin dioxide (SnO2), and 0.5-10 % by weight of chlorinated rubber and possibly up to 3 % by weight of an aqueous dispersible acrylate binder. The chlorinated rubber component is a particularly characteristic feature of this pyrotechnical charge and is included as a phlegmatization and burning rate reducing agent. |
