Zinc Phosphate/Iron Phosphate
Zinc Phosphate / Zinc-Calcium Phosphate / Iron Phosphate are surface treatment chemicals that creating crystals or film Phosphate to prevent corrosion and preparing surface before entering next process such as painting, gluing, or coating with stearate soap for reducing size process. It can be applied with wide range of materials such as steel, galvanized steel, high tensile steel, cast iron, steel wire, steel pipe and aluminum. Phosphating chemicals are product that have an important role in supported the development of various industrial groups such as automotive & auto parts, electric appliances, furniture and steel industry. We intend to develop products and services to meet customer’s requirement in terms of quality, price, delivery and safety as well as environmentally friendly products with our best technology and service mind. |

Frequently Asked Questions
Both methods yield good results, but they differ in quality control and application.
- Immersion: Suitable for complex geometries, allowing the solution to reach all areas. The significant advantage is better control over the crystal structure and coating density, resulting in more uniform corrosion resistance and paint adhesion.
- Spray: Increasingly used in continuous lines. However, control over the crystal structure and coating weight can be challenging.
Controlling the coating quality is paramount, with key factors to monitor.
- Surface Preparation: The surface must be perfectly clean and rinsed (Degreasing and Rinsing) to remove oil, grease, and rust. If the surface is not clean, the phosphate coating will not form uniformly, leading to defects.
- Activation Rinse: This step is crucial for creating numerous small Nucleation Sites on the metal surface. This promotes the formation of fine and uniform crystals, which is the key to maximizing corrosion resistance and paint adhesion.
- Solution Parameters: Stable control of pH, Temperature, and the concentration of the phosphate solution (Total Acid/Free Acid) within the optimal range.
