The composition comprising an azeotropic or azeotropic-like composition containing perfluoroheptene and a chlorotrifluoropropene.
A method of removing residue from a surface comprising contacting the surface with a composition comprising an azeotropic or azeotropic-like composition comprising perfluoroheptene and a chlorotrifluoropropene, and recovering the surface from the composition.
A method for depositing a fluorolubricant on a surface comprising:
- a. combining a fluorolubricant and a solvent, said solvent comprising an azeotropic or azeotropic-like composition containing perfluoroheptene and a chlorotrifluoropropene,
- b. contacting the combination of lubricant-solvent with the surface, and
- c. evaporating the solvent from the surface to form a fluorolubricant coating on the surface.
