Krytox™ AUT 2045 is a white grease based on PFPE. PFPE lubricants demonstrate outstanding product life and unequaled performance. AUT 2045, like most Krytox™ greases, combines the base oil with polytetrafluoroethylene (PTFE) powder as a thickener. The use of PFPE as a base oil provides superior chemical and thermal stability to all Krytox™ grease product lines.Information provided by Chemours Krytox |
