"Chitosan anodizing" does not discolor like dyeing and has excellent corrosion resistance, providing a reliable shine as a coating. The standard coating thickness is 6μm and 9μm. The naturally occurring golden color can be used as colored anodizing. The coating contains hydrated alumina and chitosan, and unlike other anodized coatings, it does not release substances such as S (sulfur) or P (phosphorus), preventing the release of contaminants that could interfere with semiconductor manufacturing equipment. 【Features】 ■ Provides a beautiful appearance ranging from light yellow to gold to the product ■ High sunlight durability, with minimal color change ■ High corrosion resistance, making it safe for outdoor use ■ Does not contain heavy atoms above AI in the coating ■ Prevents the release of contaminants that could interfere with semiconductor manufacturing equipment *For more details, please refer to the PDF document or feel free to contact us.
