Topcoat or Anodizing Replacement with Saphiral®: Innovative Coating Solutions
Aluminum surfaces are often subjected to anodizing processes to protect them from corrosion, mechanical influences, and chemical stresses, or to give them a desired coloration. However, the classic anodizing process also brings challenges, especially with certain alloys and manufacturing processes.
The Alternative to Anodizing for Uniform and Resistant Aluminum Surfaces
Many aluminum alloys show an uneven appearance with undesired discolorations after anodizing. Moreover, optical anodizing is often not feasible with cost-effective die-casting processes, which limits the application possibilities of aluminum parts. Therefore, there is an increasing demand for alternative coating solutions that are suitable for almost all alloys and manufacturing processes while ensuring a uniform appearance.
EPG AG has developed a solution that meets these requirements with its innovative Saphiral® coating system. Saphiral® has proven particularly successful in the aviation industry, as it enables uniform and color-adaptable surface finishing while offering high scratch resistance and chemical stability.
Saphiral® – Perfect Surface Protection for Aluminum
One of the biggest advantages of Saphiral® is its flexibility in color design. While color options are limited and color baths are costly in the classic anodizing process, Saphiral® allows for easy adaptation of coloration to individual customer requirements. Smaller batch sizes or specific color shades are easily achievable, and once developed, colors can be reproduced at any time.
