Comprehensive Solutions for Surface Treatment of Aluminum and Aluminum Alloys

1. SY-201 Alkaline Degreaser for Aluminum

It replaces conventional aluminum surface degreasing and is also known as a “one‑step pretreatment solution,” superseding the traditional three‑step pretreatment process. The treated surface retains aluminum’s original luster, with corrosion levels reduced to just one‑fifth of those achieved by conventional methods. This product is particularly well suited for aged aluminum alloy profiles; moreover, it is ideally compatible with thin‑walled aluminum alloy components produced via stamping and drawing, thereby expanding the range of applications beyond standard aluminum extrusions.

2. SY-204 ****** Alkaline Etching Additive

It delivers ultra‑low corrosion, extending the service life of alkaline etching solutions, and produces a bright E6 finish on aluminum and aluminum alloy surfaces. Free of nitrates, chromium salts, and chlorides, it is environmentally friendly and does not form precipitates even at very high aluminum concentrations. The company uses this product in persimmon‑shaped cookware, achieving the same gentle, refined finish as Korean‑made products.

3. SY-301 Anodizing Additive

SY-301 produces aluminum oxide films with a silvery-white appearance and a fine, uniform surface. It lowers the sulfuric acid concentration, extends the service life of the anodizing bath, and optimizes the electrical conductivity of the electrolyte. According to operator feedback, at the same current density, the cell‑end voltage is 3 V lower than before, resulting in a 16% reduction in energy consumption, while the operating temperature can be maintained at 30°C.

4. SY-650 Aluminum Alloy Trivalent Chromium Sealer

It is used for non‑hexavalent chromium passivation of aluminum alloys, aluminum die‑castings, and magnesium alloys, and can also be applied to the post‑treatment of anodized coatings. Its corrosion resistance surpasses that of hexavalent chromium passivation; after an accelerated fog test, initial white rust does not appear until after 336 hours, resulting in a uniform, transparent, slightly tinted coating with excellent heat resistance.

5. SY-357 Aluminum Alloy Low-Temperature Sealer

It effectively enhances sealing quality, offers rapid hole‑sealing, and boasts a long service life. The treated anodized layer exhibits excellent corrosion resistance, with a relatively thick film, no green‑tinting, and a high degree of surface smoothness.
