The volatile organic compound (VOC) content of coating formulations, which causes ozone formation in the environment, has now been reduced up to 80% by using supercritical carbon dioxide to replace volatile organic solvents in conventional coating formulations. Toxic solvents classified as hazardous air pollutants by the Clean Air Act can be totally eliminated. The concept can also be applied to high-solids coatings (1) to further reduce VOC emissions and (2) to improve coating performance by using higher molecular weight polymers. Commercial fluid delivery equipment and spray guns are now available. The technology is being demonstrated on industrial spray lines.
