KDNP Performance and Compatibility
In addition to qualification testing, KDNP has been successfully evaluated against LS for performance in a variety of applications such as the CCU-63, TOW missile initiator and PVU-12/A percussion primer. KDNP has compatibility which is equal to or greater than LS with a variety of ordnance materials and has substantially greater output on a weight basis in pressure-time (closed bomb) testing. Significantly, KDNP may be conveniently recrystallized to a particle size appropriate for use in a variety of systems so may be tailored for use as either a (small particle) component of a bridgewire slurry or a (large particle) constituent of a stab primer.
