AbstractThe regulatory environment surrounding the application of coatings is growing increasingly challenging. Complying with these regulations has spawned a myriad of new technologies such as waterborne, powder, and (more recently) the use of carbon dioxide for viscosity reduction. The U. S. Army Tank‐Automotive Research, Development, and Engineering Center (TARDEC) has sponsored a program under the Army Acquisition Pollution Prevention Program involving the University of Detroit Mercy (UDM) to develop a lower VOC (volatile organic compounds) Chemical Agent Resistant Coating (CARC) using the carbon dioxide process. This complements the waterborne program that is already well into the development phase. The carbon dioxide process not only allows lower VOC coatings to be used, but the decompressive atomization results in improved transfer efficiency, which benefits both overall emissions and potentially the economics of the paint application process. The reduced VOC coating applied using the carbon dioxide process program is in the trial phase and large components have been painted successfully in production facilities.
