A liquid lubricant or spray-on coating consisting essentially of polytetrafluoroethylene particles which are sintered and ground and then physically dispersed in a tricresyl phosphate carrier medium. The particles are pre-wet with aliphatic naphtha and are coated with 10 W. to 70 W. oil having a lower miscibility in tricresyl phosphate and a lower specific gravity than tricresyl phosphate. The diameter of particles is in the range of about 0. 5 microns to about 20 microns. The stability of the dispersion is achieved by lowering the specific gravity of the polytetrafluoroethylene particles by coating the particles with 10 W. to 70 W. oil.

A liquid having solid fluorocarbon particles, a buoyant medium, a carrier medium, and a vehicle diluent is disclosed. Said lubricant may be sprayed on a surface whereupon the diluent will vaporize having a coating which may include fluorocarbon particles, 50-70 weight mineral oil and tricresyl phosphate.

The present invention relates to a non-aqueous coating composition having solid lubricant particles. A low specific gravity oil coats the particles to lower the specific gravity of the particles. A high specific gravity oil disperses the coated particles. The high specific gravity oil is high relative to the low specific gravity oil. The coating of the low specific gravity oil acts as a buoyant medium to suspend the particles in the high specific gravity oil, which acts as a carrier medium. A chlorinated solvent vehicle constitutes 20 to 90 percent of the entire composition.
