Product Description
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.
