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.

SY-302 Wide-Temperature Rapid Film-Forming Agent

SY-302 wide‑temperature rapid film‑forming agent is a colorless to pale blue liquid, suitable for sulfuric acid anodizing of aluminum and its alloys. Sulfuric acid anodizing baths containing this additive exhibit a faster film‑formation rate, reaching up to 1 µm/min, facilitating the production of thick oxide films while maintaining high process efficiency. Compared with conventional sulfuric acid anodizing, it can improve productivity by 20–40%. Moreover, it offers a broad operating temperature range: qualified oxide films can be obtained at temperatures below 30°C, with uniform thickness, enhanced hardness, and excellent sealing performance.

SY-301 Anodizing Agent

SY-301 anodizing additive is a white, powder‑form additive used in the anodizing of aluminum and aluminum alloys. It produces anodized films with a silvery‑white appearance and a fine, uniform surface texture. Additionally, it lowers sulfuric acid concentration, extending the service life of the anodizing bath, and tolerates an aluminum content of up to 28 g/L. It optimizes the electrical conductivity of the electrolyte, enhancing film‑formation efficiency—increasing the deposition rate from the conventional 0.33 μm/min to 0.8 μm/min—thereby reducing electrolysis time, saving energy, and broadening the operating temperature range, with a permissible operating temperature of up to 30°C.

SY-300 Hard Anodizing Agent

SY-300 hard anodizing agent is a white powdery solid used in sulfuric acid‑based hard anodizing. Compared with conventional low‑temperature anodizing, it is more economical and energy‑efficient. Under adverse anodizing conditions, it can slow the dissolution of the oxide film, improve film thickness uniformity, and exhibit reduced sensitivity to fluctuations in temperature and current density during anodizing, while also being suitable for use at elevated temperatures.

SY-204 Alkaline Etchant

SY-204 alkaline etchant is a pale yellow, alkaline liquid that contains no nitrates, chromates, or chlorides. In alkaline etching baths for aluminum and aluminum alloys, it effectively suppresses over‑etching, surface pitting, and enhances surface brightness—achieving the “bright E6 finish” specified in German standards. It also removes minor surface irregularities and burrs, such as tool‑mark lines from machining, abrasions, and scratches, leaving the aluminum surface with a uniform, fine sandblasted decorative finish. The product is non‑hazardous to humans and is both economical and environmentally friendly.

SY-204B Long-Lasting Alumina Alkali Etchant

SY-204B long‑acting aluminum alkaline etchant is a neutral liquid product. When combined with NaOH, it forms an alkaline etching bath that provides matting and leveling effects, enabling matte etching of aluminum. The purpose is to impart a satin‑matte or matte finish to aluminum parts that have not undergone mechanical machining or polishing, prior to anodizing. SY-204B increases the tolerance of Al³⁺ ions in the alkaline solution from 40 g/L to 140 g/L.
