Abstract
Abstract 1. An explosive composition consisting of pellets of a crystalline high-explosive compound selected from the group consisting of pentaerythritol tetranitrate, cyclotrimethylenetrinitramine, cyclotetramethylenetetranitramine, tetranitromethylaniline, and trinitrotoluene, said explosive compound being coated with an epoxy hydroxy polyether nonreactive with the high-explosive compound and which is at least partially cured by means of a curing agent nonreactive with the highexplosive compound, said epoxy hydroxy polyether being present in the amount of 3-15 percent by weight of the mixture of highexplosive compound and epoxy hydroxy polyether.
