Molybdenum disulfide improves on lubrication and sustains lower friction even at higher temperature of 300 Celsius (6 intervals of 10 min. heating)
Kashima Coat can also prevent melting and scuffing in high-temperature automotive applications such as engine pistons.

Electrical breaking voltage of conventional hard anodizing is approx. 1 µm per 10 voltages, but Kashima Coat improves on electrical resistivity by 50% and erosion by overheating.
Kashima Coat is suitable for insulating parts for computer applications as well.
