Abstract: A lubricant composition comprising a perfluoropolyether lubricant and fluorinated ketone solvent is described. The lubricant composition can be applied as a coating to a substrate such as magnetic media. After the coating dries, a thin uniform lubricant film covers the substrate surface. The fluorinated ketone solvent can solubilize a wide range of perfluoropolyether compounds but not potential contaminants such as water and hydrocarbons. Additionally, the solvent has low potential to adversely affect global warming.
