  • Patent number: 11802098
    Abstract: The invention relates to a cast explosive composition. A process for formulating a homogenous crosslinked polymer bonded explosive composition comprising the steps of: i) forming an admixture of precure castable explosive composition, comprising an explosive material, a polymerisable binder, and a cross linking reagent which comprises at least two reactive groups each of which is protected by a labile blocking group, wherein the labile blocking groups, comprise at least one resonant acoustic mixing stimulus labile linkage, ii) applying resonant acoustic mixing stimulus to the admixture, causing the at least one resonant acoustic mixing stimulus labile linkage to be removed and release said cross linking reagent, to cause the cure process to start.
