ABSTRACT:
A lubricating composition is provided which is a stable dispersion of a lubricating fluid such as a natural or synthetic petroleum distillate, and a finely divided polymeric fluorocarbon powder such as polytetrafluoroethylene such as Teflon and a silicon dioxide powder such as a fumed silica. The composition is best provided by utilization of a disc impeller at elevated temperature to attain a moisture-free, even dispersion of the Teflon and the silica in the fluid. The lubricating composition is particularly useful in wide temperature range service, particularly so at extremely high and low temperatures.
