Thermal Coating for Insensitive-Munitions Technologies

Abstract

The U.S. Army is evaluating coatings for ammunition containers. An intumescent coating system for fire and heat protection is required for packaged 60-mm mortar cartridges to pass fast cookoff requirements. An intumescent coating has all the properties of ordinary paint; furthermore, this coating will not sustain combustion. Consequently, it will not burn and will provide a high degree of protection to the subsurface. Upon exposure to flame or heat, it immediately foams and swells, contributing an effective insulation and heat shield for the subsurface. In the event of fire, rather than contributing to the obstruction, it activates, prevents any flame spread, and eliminates flashover between walls and ceilings. For this project, the coatings primarily function as a defense in case of fire and prevent detonation on ammunition containers.
