1. A process for formulating a homogenous crosslinked polymer bonded explosive composition, the process comprising:
forming an admixture of a pre-cure castable explosive composition, said composition comprising an explosive material, a polymerisable binder, and a microencapsulated cross linking reagent, said microencapsulated cross linking reagent comprising a cross linking reagent encapsulated in a microcapsule, wherein the microcapsule comprises at least one shell wall polymer, wherein the microcapsule's shell wall polymer comprises at least one resonant acoustic stimulus labile linkage;
wherein applying a resonant acoustic stimulus to the admixture causes the microcapsule to rupture and release said cross linking reagent.
