MIL-PRF-87895A

Abstract

This specification covers one type of polymeric basic hot-melt general purpose bomb cavity lining material for coating the internal wall of bombs prior to loading with EAK (Ethylene diammonium dinitrate Ammonium Nitrate Potassium nitrate) and EALK (Ethylene diammonium dinitrate Aluminium Ammonium nitrate Potassium nitrate) explosives. <b><u>Intended Use:</u></b> The hot melt polymeric compound covered by this specification is military unique. It is intended for use as a protective coating for fabricated metal cases in applications where charges of ammonium nitrate based high explosives are melt cast into the case of a weapon. Such coatings provide a barrier to the corrosive effects of the fill upon the case and a cushion to mechanical impact for the explosive. Additionally, the polymeric material does not contain incompatible components such as copper, nickel, zinc, cobalt and sulfur found in natural products, and is therefore nonreactive with such explosive fills. This is essential due to the amplification of irreversible growth which results in exudation related maintenance problems of serviceable munitions, rendering them unserviceable. <br>
