Abstract : An object of the present invention is to provide a novel process for coating particulate, crystalline high explosive compounds and compositions, such as RDX (cyclotrimethylenetrinitramine), HMX (cyclotetramethylenetetranitramine), PETN (pentaerythritol tetranitrate), tetryl (2,4,6-trinitrophenylmethylnitramine), TNT (2,4,6-trinitrotoluene) and mixtures thereof, such as Composition B (60% RDX + 40% TNT), with a wax desensitizing material, which reduces or eliminates the disadvantages of prior art methods. Another object is to provide a particulate high explosive containing an improved coating of desensitizing material. Finely divided, crystalline high explosive compounds and compositions are provided with a desensitizing coating of wax by mixing the explosive particles with an aqueous dispersion of the wax containing a soluble salt of a higher fatty acid dispersing agent, e.g. sodium stearate, and adding barium chloride or the like to precipitate the dispersing agent as a water-insoluble fatty acid compound and break the dispersion, thereby coating the explosive particles with an intimate mixture of the wax and the insoluble fatty acid compound.
