Non-toxic heavy-metal-free zinc peroxide-containing, ir tracer compositions and ir tracer projectiles containing same for generating a dim visibility ir trace

Abstract From the Canadian patent

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 non-metallic 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 …
