The first thing that comes to mind when talking about lubricants is, without a doubt, oil. People have been using plant and animal fat-based substances for greasing purposes for centuries. Petroleum byproducts came into the picture in the middle of the 19th-hundreds, and they are widely used today. However, fossil oil comes from finite sources. We have to look for an alternative. Secondly, oil is flammable. Thirdly, oil is expensive and pretty challenging to dispose of. The environmental impact of oil-based lubricants is indubitable.
There is a dire need for safer, cleaner, eco-friendlier, and more effective lubricant that does not deteriorate under extreme conditions.

2For other application like in gear oil, what about the dispersancy? can it form a stable colloid or solution without any impact on other additive components existing in oil?
3Any test on oil seal? any impact on the rubber wear and potential leakage

25 Feb 2020 - 20:00Hello Mr. Zhimin Liu. Thank you for your questions.
First of all, I would like to separate 2 dispersions we have IW-5000 – is water-based. The third-party data is showing about 20% improvement in heat transfer property of water. Cush effect is quite common for homogeneously dispersed metal-based solids.
However, in addition to cooling capacity, IW-5000 possesses very high extreme pressure properties (800+kgf at 2.75-3.25% dosage), as well as antiwear and antifriction. Please bear in mind IW-5000 is a water-based dispersion. Besides cooling and tribological performances IW-5000 gives some corrosion inhibiting properties, however, we do recommend to add and adjust corrosion inhibitors, antifoams, biocides according to your specification targets. We can recommend some components to add to your request.
For the second point. Stability is very important for any solid in liquid dispersions. IF-WS2 are not soluble thus stability can not be tested using the same methods as for soluble oil additives. Impact on other additives needs to be discussed further. Any additive requires balancing and adjustment to create a stable and fully formulated lubricant.
IF-WS2 or Inorganic Fullerene like Tungsten Disulfide is a new generation of already known one of the best solid lubricants on the earth: Tungsten Disulfide, or WS2.
We haven’t seen any effect on rubber and seals.
