Abstract

The present invention provides a new and improved method of producing coating materials comprising the steps of providing a first organic material which is solid at room temperature, providing a second organic material which is solid at room temperature and which is substantially different in chemical composition from the first organic material, providing a source of supercritical fluid, providing a first container having a mechanical agitator, providing a second container, introducing the first and second organic materials and the supercritical fluid into the first container and mechanically agitating such materials and the supercritical fluid, and discharging the contents of the first container into the second container so as to collect substantially all of the first and second organic materials in the second vessel, the second container being maintained at a lower pressure than the first container.
