Due to the strong adsorption ability and easy staining characteristics of the anodization film, various staining methods have been developed accordingly. Staining is the process of immediately immersing the cleaned Aluminium Profile in a dye-containing solution after anodization. The pores of the anondization film are dyed with various colors due to the adsorption of dyes. This method is fast, produces bright colors, and is simple to operate. After staining, the dye can be firmly attached in the membrane pores through a sealing treatment, which enhances the corrosion resistance, anti-fouling ability, and maintains the bright color of the Aluminum Extrusion Profile. Therefore, it has seen rapid development and application. Aluminium Profiles Window and Door, can exhibit different surface effects compared to powder coating after anodization.
