 Slickote® Solid Film Lubricant Technical Information

 

 


 

Typical Uses For Solid Film Lubricants:

  • Provide lubrication where dust or contaminates may interfere with lubricating oils.
  • For sliding motion applications such as plain and spherical bearings, flap tracks, hinges, threads, and cam surfaces.
  • On extreme heavy loads to reduce wear, prevent galling or seizing of metals.
  • Where conventional lubricants are difficult to apply or retain.                     
  • When mechanisms are operated at infrequent intervals or are lubricated for life.
  • To provide corrosion, chemical and solvent protection.                             
  • High/Low temperature applications not suitable for oils. (-68 to 204 deg C)
  • Vacuum applications where oils become volatile.

    How Solid Film Lubricants Work
    Applied by spray, dip, tumble or brush onto clean prepared metal surfaces to coating thickness of .0002 to .0005 inch (most cases). Air dry or thermal cure depending on the binder system. 
    The cured lubricant coating prevents metal to metal contact which reduces wear and friction between surfaces.

    Coefficient of Friction 
    The ratio of force / mass. Example: If it takes a 2 lb force to move a 100 lb object, the coefficient of friction is .02
    Kinetic (in motion) coefficient of friction is slightly lower than static (at rest) coefficient of friction.
    As the load increases, the coefficient of friction decreases, to as low as .02 under heavy loads.
    Coefficient of Friction is independent of temperature within the specified use limits.
    The coefficient of friction is lower for rotating motion than for sliding motion.
    The coefficient of friction may be reduced by burnishing.

    Lubricating Materials

      Molybdenum Disulfide - Extremely effective lubricant under heavy loads up to 750 deg F (1400 deg F in vacuum). 

      Graphite - Softer than Molybdenum Disulfide. An effective lubricant at temperatures up to 2000 deg F. Not recommended for use in a vacuum (requires oxygen on surface). Electrically conductive. Restricted from use in some military and commercial specifications.

      PTFE. Polytetrafluroethylene. Good for light lubrication. Has the lowest coefficient of friction. Excellent for corrosion resistance, and anti-Stick/ release. 

      Tungsten Disulfide - Similar to Molybdenum Disulfide but harder. Effective to 850 deg F.
