ABSTRACT:
Coatings, such as paint or oil, are stripped from the surface of a coated object by circulating a stream of a stripping composition in a gaseous state at ambient temperature and pressure into contact with the surface. The stripping composition is normally a liquid at ambient temperature and pressure and has a partial pressure of at least 5 mm of Hg. at ambient conditions. The contacting procedure is conducted substantially in the absence on the surface of liquid condensate of the stripping composition.
