ABSTRACT:
A method and apparatus are provided for spraying a solvent-borne composition with reduced emission of organic solvents by exchanging a portion of the organic solvent diluent with a compressed fluid such as carbon dioxide, by adding the compressed fluid under pressure to maintain low viscosity and to facilitate solvent separation, separating a portion of the organic solvent, and spraying the resulting composition with compressed fluid.
