High non-adhesion of paint and adhesives! Introducing effective coatings for paint primers and adhesive pre-treatments.
"Chromic acid anodizing" is a coating obtained by anodizing aluminum in an anhydrous chromic acid aqueous solution. It provides excellent corrosion resistance, especially for high-strength aluminum alloys with a high copper content, as well as heat resistance and a crack-free coating that withstands rapid temperature changes and repeated fatigue, making it suitable for aircraft structures and functional components. The chromic acid in the electrolyte acts as a corrosion inhibitor and is safe even if it remains in the product, allowing it to be used in assembled parts. 【Features】 ■ Opaque grayish-white to gray appearance ■ High non-adhesion to paints and adhesives, effective as a primer for painting and pre-treatment for adhesion ■ No damage to the product even if the electrolyte remains ■ Prevents the reduction of corrosion resistance due to crack formation ■ Minimal dimensional changes regardless of dyeing or non-dyeing *For more details, please refer to the PDF document or feel free to contact us.
