  • Patent number: 4608282
    Abstract: The invention is a composition for coating surfaces with a thin film containing fluoropolymer particles, a method for producing this composition, as well as a method for applying it to a surface. More particularly, the composition includes a carrier medium, such as a synthetic base stock, which has particles of a fluoropolymer, such as ground and sintered polytetrafluoroethylene, well dispersed within it. A solvent, such as 1,1,1-trichloroethane, is blended with the fluoropolymer containing carrier medium, most preferably in either a 32 to 1 ratio or an 8 to 1 ratio. The result is a low viscosity dispersion of the carrier medium, which itself has a dispersion of the fluoropolymer particles. When the composition is applied to a surface, the lowered viscosity aids in obtaining a thinner film of the grease and also enhances the penetration of the fluoropolymer particles into the surface. Advantageously, the solvent is allowed to evaporate from the surface, thus leaving an even thinner film of the grease.
