EPG AG has developed Saphiral®, a coating solution that can overcome the optical disadvantages of the anodizing process. Either with the help of a topcoat that is adapted to the customer’s color preferences and functionalities, or without anodizing, Saphiral® can also be applied directly to an uncoated surface. Due to the very thin layer thickness – in the range of 5 to 15 micrometers – the haptic feel of the metal is preserved.
In addition to the optical enhancement of aluminum, Saphiral® offers excellent properties to resist mechanical and chemical influences: whether abrasion resistance, scratch hardness, and also resistance to e.g., hand perspiration, all customer requirements can be individually adapted.
