Abstract
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.

A non-aqueous coating composition consisting essentially of,
- solid lubricant particles,
- a low specific gravity oil coating the particles to lower the specific gravity of the particles,
- a high specific gravity oil having the coated particles dispersed therein, wherein the high specific gravity oil is high relative to the low specific gravity oil, whereby the coating of low specific gravity oil acts as a buoyant medium to float the particles in the high specific gravity oil which acts as a carrier medium, and
- a chlorinated solvent vehicle which constitutes 20 percent to 90 percent of the entire composition.
