Instructions:
1. Proportion of adding water: 1:5-10;
2. For realizing the optimal passivating effect, it's recommended the precise cleaning procedure is: degreasing →
water cleaning → water cleaning → surface conditioning → passivating → water cleaning → water cleaning → drying;
3. Temperature: soak it under the normal temperature with the soaking time of 5-10min;
4. Maintenance of working fluid: the pH value and concentration of tank fluid will change during the process of product working.
It needs particularly monitoring the index and keeping the tank liquid within the normal specified range;

inverted to make sure the application effect;
2. Add the passivating agent into the clean tank and use it when the liquid level covers the workpiece;
3. The pH value and concentration of tank fluid will change during the process of product working. It needs particularly
monitoring the index and keeping the tank liquid within the normal specified range;
4. The passivating agent in the tank will be consumed after using it for a period of time, and shall be supplemented timely;
Precautions:
1. The product must be added in purified water but not ta water;
