A new PTFE/NanoDiamond coating with twice the durability and up to 66% less friction than current products has the potential to cost-effectively reduce CO₂ output and fuel demand, as well as to improve equipment lifespan in industries such as automotive, aerospace and industrial machinery.

A liquid dispersion of 4-6nm NanoDiamond particles with surface chemistry that has been specially created to integrate the particles with PTFE molecules without the use of additional surfactants, uDiamond^® Vox D is the latest addition to Carbodeon’s range of NanoDiamond materials.

The improvements in durability and friction come in part because of the properties of the diamond material that the particles are composed of, but equally important are the changes to the overall coating structure caused by the presence of the particles themselves. The use of hard particles to improve the durability of coatings is well known, but the combination of small size and surface functionalization in the new coating means that Carbodeon’s particles are interfaced with PTFE molecules in a fundamentally different way.

Formulation of the coatings is straightforward – the uDiamond Vox D is supplied as an aqueous or solvent-based dispersion ready for direct mixing into a PTFE coating, followed by application by spray or screen printing with little or no change to the process parameters.
