ABSTRACT:
Self-supporting water-bearing explosive products, e.g., for use as primers and in blasting and seismic charges, contain discrete cells of an aqueous solution of an inorganic oxidizing salt and/or of an amine salt encapsulated by a crosslinked (thermoset) resin matrix. The products are sensitized by a dispersed solid high explosive and/or gas bubbles or voids. Preferred primers are sensitized by PETN and are rigid. The products are made by crosslinking a liquid polymer in the continuous phase of an emulsion which contains the aqueous solution as a discontinuous phase.
