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.
描述了一种润滑剂组合物,其中包括
全氟聚醚润滑剂和
氟酮溶剂。该润滑剂组合物可以涂覆在磁性介质等基底上。在涂层干燥后,薄而均匀的润滑膜覆盖在基底表面。
氟酮溶剂可以溶解广泛的
全氟聚醚化合物,但不能溶解潜在的污染物,如
水和碳氢化合物。此外,该溶剂对全球变暖的不良影响潜力较低。
