A maximum of 7 percent Class 5 RDX may be used in the formulation to improve processing characteristics.
Addition of Class 5 RDX shall be made at the expense of Class 1 RDX. The total RDX weight shall be between 62
and 66 percent, with a nominal weight of 64 percent.
2
Typical equivalent analyses of binder components used to establish nominal composition are as follows:
PolyBD = 0.82 milliequivalent weight per gram (meq/g) (hydroxyl value) or 1219.5 g/eq (equivalent weight),
IPDI = 113.47 meq/g (equivalent weight),
DHE = 500 mg KOH/g (hydroxyl number) or 112.2 g/eq (equivalent weight),
NCO/OH Ratio = 1.0/1 (nominal).
3
Triphenylbismuth (TPB) is the recommended catalyst. Recommended nominal value is 0.02%.
4
Dibutyltin dilaurate (DBTL) may be substituted for TPB using between 0.002% and 0.02%. However, TPB is the
recommended catalyst.
3.4 Cured explosive requirements (M102). The cured explosive shall meet the requirements specified in Table
II.
