The coatings used on military hardware must resist increasingly sophisticated chemical and biological weapons. Moreover, they must also withstand the decontamination that typically involves a complete washdown with concentrated bleach and solvents. The chemical agent resistant coatings (CARC) system currently applied to virtually every tactical and combat vehicle in the U.S. Armed Forces is a vital component of the overall strategy of the U.S. Department of Defense (DOD) to protect soldiers from chemical and biological agent attacks. As the CARC system celebrates its 25th year in service, advances continue to be made to extend coating life, improve corrosion resistance, reduce environmental impact, enhance ease of use and make application processes more economical.
