During the patented computer-controlled “deep dyeing process” the polymer matrix is penetrated by UV absorbers and/or colour pigments. In this way the films are directly tinted and not merely coated with colour, thus attaining the best possible colour stability and resistance to abrasion.
Aluminium is heated in a high vacuum and vapour plated onto the film. The thickness of the metal layer is controlled to ensure unsurpassed visual quality.
During the sputtering process (vacuum coating by cathodic Sputtering) metal atoms are introduced into the surface of the film. Alloys and metals such as gold, silver, tin, chromium nickel, copper, titanium or stainless steel are processed using this procedure.
