Our coloured metal surfaces are not coated with a layer of coloured pigments. The colour is produced by the interference of light on a colourless, transparent metallic oxide layer, whose thickness, together with the colour of the incident light, determine the colour. This effect is comparable with the colours of a film of oil on water or a film of paint on hot metal. The colours do not age or bleach with time. The oxide layers are highly resistant to chemicals, evenly bonded with the metal surface, and will neither crack nor flake off.
Added value through POLIGRAT processes
- Tinting of stainless steel, titanium alloys and zircon
- All spectral colours can be achieved, as well as black and brown on stainless steel
- Tinting of smooth, structured, shiny and matt surfaces
- Pre-treatment to achieve the required gloss level through appropriate POLIGRAT processes
Typical applications
