ABSTRACT:
Novel non-toxic, heavy-metal free, zinc peroxide-containing, IR tracer compositions are provided herein, which, when incorporated into a medium caliber IR tracer projectile and fired, produce a dim visibility IR trace. Such IR tracer compositions comprise from about 65 to about 75% by weight, of zinc peroxide; from about 15 to about 25% by weight of a fuel which consists of sodium salicylate; and an effective amount of a binder which is selected from the group consisting of calcium resinate and cellulose acetate butyrate. The total percentage of the ingredients adds up to 100%. Medium caliber, i.e., 0.50 caliber, IR tracer projectiles containing such IR tracer compositions are also provided.
