dianoir® G3, deposited at a temperature <190ºC, is ideal for coating complex shaped components and delicate materials that cannot be coated with traditional PVD technologies. dianoir® G3 is resistant to chemical products and acidic and alkaline solvents and is hypoallergenic; it is therefore highly valued for coating watch bracelets.

dianoir®G3, which is particularly suitable for watchmaking components, has the following advantages:
- excellent adhesion on brass, stainless steel and titanium alloy components
- homogeneous black color
- decorative and functional coating in one solution
- non-toxic process and biological compatibility are optimal properties for the use of dianoir®G3 in contact with the human skin
- ideal for all watch movement components that will benefit from an improvement in their tribological and decorative properties
