The raw material, e.g. titanium nitride, is put into the gaseous state. Following this it is released onto the substrate to be coated (e.g. stainless steel sheets). This is where it condenses and turns into the coating.
What are the advantages of TiN coating?
TiN has good reflection properties for infrared rays; its reflection range is almost as wide as that of gold. Titanium nitride is not a dangerous material according to EC directives. Neither does this material need to be labelled. It is not classed as water-polluting.
