Abstract
There is provided a process for vacuum drying. The process includes the steps of: depositing a liquid composition containing a film-forming material and at least one solvent onto a workpiece to form a wet layer; placing the wet layer on the workpiece into a vacuum chamber including a condenser; and treating the wet layer at a controlled temperature in the range of −25 to 80° C. and under an applied vacuum in the range of 10to 1,000 Torr for a period of 1-100 minutes; wherein the condenser is maintained at a temperature at which the solvent will condense as a liquid at the applied vacuum.
