An intumescent coating has all the properties of ordinary paint furthermore, this coating will not sustain combustion. Consequently, it will not burn, providing 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. An intumescent coating system for fire and heat protection is specified for 60-mm mortar containers. The projected intumescent coating system for ammunition containers performed unsuccessfully during testing at the Aberdeen Test Center. The complexity of this project included paint delamination, cracking and chipping after the drop, and impact-resistant test. The specified intumescent system intumescent and topcoat was supplied by NoFire Technologies Inc. and consists of a water-based A-18NV, MIL-PRF-24596, type II intumescent paint and a solvent-based topcoat Uracoat. The intumescent coating system is applied over the forest - green coating basecoat used on the containers.
