| Product Name | LG408 Free-Flake Zinc Phosphating Agent |
| Product Overview | LG408 is an environmentally friendly pre-coating treatment agent developed with advanced formulation technology, specifically designed for steel surface treatment. By optimizing the film-forming mechanism, it creates a uniform, dense, and fine zinc phosphate crystalline coating on the steel surface. This phosphating film acts as a physical barrier and chemical bonding layer, significantly enhancing the adhesion of subsequent coatings and overall corrosion resistance. Compared to traditional phosphating processes, this product offers outstanding advantages: no sludge formation, stable bath solution, easy management, and excellent environmental friendliness. |

| Bath Preparation | - LG408 Phosphating Agent: 5% – 10% - Dilute with tap water or deionized water to the working volume. Heat to the operating temperature. |
| Treatment Conditions | - Total Acid (TA): 15 – 25 points - Free Acid (FA): 0.5 – 1.2 points |
| Maintenance & Adjustment | 1.Regularly monitor and adjust the Temperature, Time, Total Acid (TA), Free Acid (FA), and accelerator concentration within the specified ranges. 2. Prevent excessive carry-over of impurities (e.g., alkalinity, chlorides, sulfates) from pre-treatment stages into the phosphating bath. 3. Add the replenisher (LG408R) based on the consumption of total acid to maintain bath balance. In case of severe contamination, a partial or complete bath replacement is recommended. |
