Tungsten Disulphide is a very low friction coating applied - at room temperature, originally developed by NASA as a dry lubricant for spacecraft components operating in a vacuum.

The applied coating follows the geometry of the tool or component with no build up on edges.

It can be used on all metals and even some plastics.

WS2 can be used on heat treated components and over many engineering coatings.

Items up to 2000kg may be treated
