- a) combining a fluorolubricant and a solvent, said solvent comprising
- i)1,2-dichloro-1,2-difluoroethylene, and, optionally,
- ii) a compound selected from N-pentane, HFE-7000, R-1233xfB, R-1336mzzZ, dimethoxymethane, R-1345mzzE, R-43-10mee, R-365mfc, tetrahydrofuran, and R-153-10mzzy, to form a lubricant-solvent combination;
- b) contacting the lubricant-solvent combination with the surface;
- and
- c) evaporating the solvent from the surface to form a fluorolubricant coating on the surface.
A composition, comprising:
- i) 1,2-dichloro-1,2-difluoroethylene, and
- ii) a compound selected from HFE-7000 and tetrahydrofuran.
