POLYMERISABLE BINDER

Abstract:

The invention relates to Polymerisable Binders, and Insensitive Munition (IM) energetic materials particularly to non-phthalate IM propellant compositions which are printed by a UV curing additive layer manufacture process. invention there is provided an additive layer deposable energetic composition suitable for use as a propellant comprising the following components in the following relative proportions: component A; from 60% to 95% by weight of a highly energetic filler comprising at least one nitramine compound; and component B: from 5% to 20% by weight of a binder, wherein the binder contains component D a UV curable binder in the range of from 3% to 12% by total weight of the formulation, at least one UV photoinitiator, component C: from 1% to 15% of a plasticiser, the percentages by weight of components A, B, D and C, together with minor additives, if any, adding to 100%.
