Abstract: Air- and/or oven-drying lubricant paint compositions are disclosed which are useful for providing dry-film lubrication for substrates. The compositions comprise a binder resin dissolved in an organic solvent, optionally containing an extender, and further containing a polyalkylene wax which may be modified or unmodified. The dry-film lubricant provides a coefficient of friction which is lower, more uniform and of a narrower range than the compositions of the art.

Abstract: A stable aqueous dispersion of a solid lubricant combination of MoS.sub.2 and graphite and an acrylic resin is used to coat bearing members to provide an air drying long lasting lubricant coating. A typical formulation is 60 to 80% water, 15 to 30% MoS.sub.2 and graphite in the weight ratio of 1.5:1 to 2.5:1 and 5 to 10% polybutyl acrylate. The MoS.sub.2 and graphite preferably have a particle size of less than 5 .mu.m.
Abstract: A process for preparing improved solid lubricants, by modifying the surface characteristics of the solid lubricants using reactive chemical compounds, is disclosed.Prior art measures anticipate combinations of modifiers and solid lubricants as lubricating mixtures but do not disclose bonding modifiers with solid lubricants.Examples of the improved modified solid lubricants are molybdenum disulfide chemically bonded to polystyrene, polymethylmethacrylate or polydimethylsiloxane.
