ABSTRACT:
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.
