SY-314 magenta colorant

SY-314 magenta colorant is a copper‑salt electrolytic coloring agent that offers corrosion resistance, lightfastness, abrasion resistance, and heat resistance—properties unmatched by conventional organic dyeing processes. It is widely used for decorative and protective finishing of aluminum surfaces and aluminum products. When applied after anodizing, this electrolytic colorant and its associated process yield hues ranging from flesh‑red to deep red, with rich, pure, and striking colors. The bath formulated with this colorant is easy to maintain, boasts a long service life, exhibits strong resistance to impurities, and offers excellent adjustability.

SY-312 Champagne Gold Colorant

SY-312 champagne‑gold colorant is a white powder used in the electrolytic coloring process following anodizing of aluminum profiles. It produces an electrolytically colored film with a light sandy yellow–beige hue, exhibiting excellent lightfastness and weather resistance. This product offers easy-to‑control processing for achieving yellow–beige shades, with minimal color variation; its wear resistance, corrosion resistance, and weatherability surpass those of standard champagne tones. However, to obtain a deeper champagne‑gold shade, a hole‑expansion treatment is required to ensure smooth production operations and superior post‑treatment sealing quality.

SY-311 Bronze Series Colorant

SY-311 bronze‑series colorant is a pale yellow powder composed of divalent tin salts, iron salts, and organic acids. It is used for electrolytic coloring of aluminum anodized coatings, enabling the production of electrolytically colored films ranging from light champagne to bronze and black. Additionally, it suppresses the oxidation of divalent tin to tetravalent tin caused by dissolved oxygen, thereby enhancing the dispersing capacity of the electrolytic coloring bath. This product contains stannous sulfate and stabilizers, simplifying the process of controlling the bath composition.

SY-313 gray colorant

SY-313 gray colorant is a gray‑white powder used for electrolytic coloring of anodized aluminum profiles, enabling the production of gray‑to‑dark gray and black electrolytic color films with uniform hue, excellent dispersibility and reproducibility, bright surface finish, and superior bath stability. Its component concentrations and ratios remain largely constant, ensuring long service life and no precipitate formation. The manufacturing process is easy to control, resulting in minimal color variation; its wear resistance, corrosion resistance, and weatherability outperform those of conventional gray colors, while also delivering outstanding gloss on the colored aluminum.
