ABSTRACT:
The present invention is directed to methods for spraying polymeric compositions with supercritical or subcritical compressed fluids such as carbon dioxide or ethane over a wider range of spray conditions to provide improved spray application quality with reduced emission of solvent. The methods are accomplished by using an elongated spray orifice to transform narrow, fishtail, liquid-film sprays to wider, feathered, decompressive sprays.
