Patent ID: 8470107

Claim:
A primer composition comprising: an explosive consisting essentially of at least one moderately insensitive explosive in an amount of about 5 wt-% to about 40 wt-% of the primer composition and optionally a sensitizer in an amount of about 0 wt-% to about 20 wt-% of the primer composition, said at least one moderately insensitive explosive chosen from nitrocellulose, pentaerythritol tetranitrate (“PETN”), 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazatetracyclo [5.5.0.0. 5,9 0 3,11 ]-dodecane (“CL-20”), cyclo-1,3,5-trimethylene-2,4,6-trinitramine (“RDX”), cyclotetramethylene tetranitramine (“HMX”), 2,4,6-trinitrotoluene (“TNT”), nitroguanidine, styphnic acid, potassium dinitrobenzofuroxan (“KDNBF”), and mixtures thereof; a plurality of fuel particles having an average particle size of greater than about 1.5 microns to about 12 microns, said plurality of fuel particles in an amount of about 5 wt-% to about 20 wt-% of the primer composition; and an oxidizer in an amount of about 35 wt-% to about 85 wt-% of the primer composition; wherein the primer composition is essentially devoid of other explosives except for the optional sensitizer and/or a propellant.
