All provided data are approximate values, depend on the application, environment and test conditions. Coating hardness HIT [GPa] measured by nano indentation according to ISO 14577. Hardness can be adapted to the application. Friction coefficient (dry) compared to the steel determined by ball-on-disc dry test with a steel sphere according to ASTM G99. During the running-in the indicated values may be exceeded. Maximum service temperature [° C] These are approximate values.
dianoir®G2, particularly suitable for watchmaking components, has the following advantages:
- excellent adhesion on components in brass, stainless steel and titanium alloys
- homogeneous black color
- non-toxic process and biocompatibility are optimal properties for the use of dianoir®G2 in contact with the human skin
- resistance to corrosion and UV rays
