Abstract
Solutions and process are described useful to produce coated HE powder granules in an aqueous slurry agglomeration process. A reaction mixture is made utilizing a lacquer stock solution comprising a binder material dissolved in a substantially aqueous-immiscible organic lacquer solvent, and an aqueous HE powder slurry solution comprising a non-aqueous soluble HE powder and an at least partially aqueous-miscible organic co-solvent. The co-solvent acts as an entrainer and improves the immiscible of the lacquer solvent in the water phase of the aqueous HE powder slurry solution, resulting in formation of HE powder agglomerates that remain stable as the solvents are removed from the reaction mixture during the agglomeration process. Further, the process is adjustable to substantially eliminate organic solvent contamination of the waste water stream.
