Zinc phosphating solution

This product can be used at room temperature, impregnated or sprayed. It is suitable for phosphating before coating of steel parts in automobile, anti-theft door, radiator and other industries. It can be matched with electrophoresis, electrostatic spraying, spray painting and other coating processes.

1、 Main technical specifications

2、 Main features

1. In the process of use, the accelerator should be added separately, and the same agent should be used in the tank and the addition, so the operation is simple and the management is convenient.

2. This product has good stability, less sediment and long service life.

3. The phosphating film has dense crystal, gray color and no ash. It can enhance the adhesion and corrosion resistance of the film and has low comprehensive cost.

3、 Application method and process parameters

1. Treatment process: degreasing → washing → pickling → neutralization washing → washing → surface adjustment → phosphating → washing → drying

2. The phosphating solution is prepared into 6% working solution, and appropriate neutralizer and accelerator are added per ton to make it dissolve and stir evenly.

3. Process parameters:

FA: 0.8-1.2pt, treatment temperature: 35-45 ℃, accelerator AC: 4-6pt

TA: 18-22pt, treatment time: dipping: 10-15min, spraying: 2-4min

4. As the concentration changes continuously in the continuous treatment process, it is necessary to measure the concentration of each index regularly to keep each index within the specified process concentration range.

4、 Packaging, storage and transportation

30kg plastic barrel packaging, storage and transportation temperature not less than 0 ℃.
