PROBLEM TO BE SOLVED: To provide a stable perfluoropolyether-based composition capable of forming a lubricating film. SOLUTION: The composition contains (A) 0.15-50 wt.% one or more perfluoropolyether oils, (B) 0.5-10 wt.% (per)fluoropolyether compound having at least one terminal group selected from carboxy, alcohol, amide, ketone, amino and alkoxy functional groups, (C) 0.01-2 wt.% organic or inorganic, solid or liquid non-fluorinated additive, and (D) 50-95 wt.% at least one fluorinated liquid selected from hydrofluoroethers, hydrofluoropolyethers and hydrofluorocarbons and having a boiling point of 20-250°C, preferably 50-190°C. The sum of the components (A), (B), (C) and (D) is 100 wt.%. COPYRIGHT: (C)2006,JPO&NCIPI |
