In order to reduce the VOC (Volatile Organic Compounds) emission from the coating processes, supercritical CO2 was used as the alternative material of thinner component in paint. However, there were few investigations of the characteristics of paint spray with supercritical CO2. In this study, spray pattern and droplet distribution on the coating surface were measured using the high speed camera images under the various conditions of CO2 additive rate. In the experiment, the additive rate of CO2 is changed from 0% to 60%. As a result, it was confirmed that the atomization characteristics was strongly influenced by the additive rate of CO2. And the spray characteristics were enhanced by the additive of supercritical CO2.
