NON-TOXIC HEAVY-METAL-FREE ZINC PEROXIDE-CONTAINING, IR TRACER COMPOSITIONS AND IR TRACER PROJECTILES CONTAINING SAME FOR GENERATING A DIM VISIBILITY IR TRACE

摘要

Novel non-toxic, heavy-metal free, zinc peroxide-containing, IR tracercompositions are provided herein, which, when incorporated into a mediumcaliber IRtracer projectile and fired, produce a dim visibility IR trace. Such IR tracercompositions comprise from about 65 to about 75% by weight, of zinc peroxide;fromabout 15 to about 25% by weight of a non-metallic fuel which consists ofsodiumsalicylate; and an effective amount of a binder which is selected from thegroupconsisting of calcium resinate and cellulose acetate butyrate. The totalpercentage ofthe ingredients adds up to 100%. Medium caliber, i.e., 0.50 caliber, IR tracerprojectiles containing such IR tracer compositions are also provided.
