"NDCO (Nadeko)" is a composite plating that allows for the uniform dispersion and co-precipitation of nano-diamond (ND) particles, which have traditionally been difficult to achieve, in the order of 10 to 100 nm. Since it co-precipitates ND particles with high hardness, it excels in wear resistance and has good sliding properties, minimizing aggressiveness towards the counterpart material. Additionally, by incorporating PTFE particles along with low-friction ND particles, even lower friction can be achieved. [Comparison with conventional hard chrome plating] ■ Friction coefficient: Reduced by 20% ■ Wear resistance: Improved by 50% ■ Aggressiveness towards counterpart material: Reduced by 70% *For more details, please refer to the PDF document or feel free to contact us.

Electrocoating is a painting method that forms a coating film by passing electricity between the product and the electrode in an electrocoating paint. Depending on whether the object being coated is the anode or cathode, it is divided into anionic electrocoating and cationic electrocoating. This method allows for easy control of film thickness and enables the formation of a uniform coating film on products with complex shapes. Additionally, because it uses water-based paint, the amount of organic solvents used is minimal, which is effective in reducing VOCs (Volatile Organic Compounds). 【Features】 ■ Forms a coating film by passing electricity between the product and the electrode in electrocoating paint ■ Allows for easy control of film thickness and the formation of a uniform coating film on products with complex shapes ■ Minimal use of organic solvents due to the water-based paint ■ Effective in reducing VOCs *For more details, please refer to the PDF document or feel free to contact us.
