BY-838 room temperature color film phosphating agent

Phosphating at room temperature has entered the era of all-weather, slag-free, high-speed and free-adjustable color film. After years of efforts, our company has launched a new generation of high-performance room temperature fast phosphating agent BY-838, which does not contain heavy metal salts in normal phosphating. class.

BY-838 has high speed penetration and fast film forming properties. The appearance of the film is colored, and BY-838 also shows the following advantages:

1 The phosphating process is simple, and the whole process of surface conditioning, phosphating and passivation is completed in the same tank. After phosphating, it can be washed without water, and it is not necessary to add any accelerator alone during use.

2 Phosphating film is dense, continuous, smooth in appearance, and thin film (0.8-1.5 microns). After coating, the film has high gloss and can save paint.

3 It does not contain toxic and harmful substances such as sodium nitrite, chromium ion and free fluorine. The environmental benefits are good. No harmful gases are generated during the phosphating process, and there is no corrosion or slag on equipment and plant.

4 The equipment investment is small, the production line is short, the floor space is small, and there is no need for special equipment for heating and three waste treatment.

5 Phosphating costs are extremely low, only 1/5 to 1/10 of the cost of ash phosphating. Can be made into powder or liquid.

6 Phosphate galvanized steel sheet, zinc material and zinc aluminum alloy material, suitable for painting, spray coating and electrophoretic coating, especially for electrostatic powder spray and cathodic electrophoresis coating.

Note: The total acidity of BY-838 phosphating working solution should be greater than 15 points.
