#203 Lubricating Paints

Category : Special paints
March 6, 2015

Lubricating paints are used in areas where it is difficult to lubricate with oil/grease commonly used, in areas that are not compatible with greasing by such agents, and in rolling bearings used under a special atmosphere such as in a vacuum. They are also used to reduce friction between sliding objects and/or to improve resistance to abrasion and corrosion. With the developments in the sectors of precision industry and semiconductor manufacturing in recent years, dust- and maintenance-free features are required, and thus the self-lubricating properties achieved by these lubricant is increasingly demanded.
Types of lubricating paints include molybdenum disulfide lubricating paints, tetrafluoroethylene lubricating paints, graphite lubricating paints, and boron nitride/tungsten disulfide lubricating paints.

(1) Molybdenum disulfide lubricating paints

This type of paint is used for the following:

1. Friction area of a machine where micro-vibrations are likely to occur
2. Plastic forming such as wire drawings/cold extrusion of stainless steel, titanium, aluminum, etc.
3. Lubrication of rolling bearings, sliding bearings, and screws used in a special atmosphere such as in a vacuum or under high/low temperature environments
4. Antirust and lubrication of springs used for railroad vehicles and automobiles
5. Lubrication of cameras, office machines and other machines

and other purposes.

(2) Tetrafluoroethylene resin lubricating paints

This type of paint is used for a wide range of applications from bridges, dams, and floodgates operated under low-speed / high-load conditions to kitchen instruments such as frying pans.

For example, it is used for the following:

1. Fulcrum of bridges and bearings of floodgates that are used under high-load / low-speed conditions
2. Bearing alloys and glass foundation cloth, etc. (used as lubricants by impregnating them with this paint)
3. Improving sliding performance of clocks, sewing machines, and irons, etc.
4. Adding non-viscous properties to the instruments for food, fibers, paper manufacturing, and kitchen
5. Lubrication of general machinery

and other purposes.

(3) Graphite lubricating paints

This type of paints is used in an atmosphere where it is not possible to use molybdenum disulfide or tetrafluoroethylene resin.

For example, it is used for the following:

1. Lubrication of sliding components used in a high-temperature atmosphere such as boiler's heat exchanger or casting equipment, as well as ones used in an environment where there is the effects of radiation such as a nuclear reactor
2. Lubrication during hot working processes of metals such as casting, drawing, or extrusion, as well as mold releasing during hot working processes of glass

and other purposes.

(4) Boron nitride/tungsten disulfide lubricating paints

This type of paint has the following uses:

1. High-temperature mold release agent
2. Lubricants for breaking in a machinery

and other uses.
