This product is high concentration room temperature zinc iron series phosphating agent, the film layer crystallization is meticulous, appearance appears blue or color red phosphating film.It can be compatible with electrophoresis, plastic spraying and baking process, and has the advantages of good adhesion.This phosphating agent is used at room temperature, simple to operate, low cost, less sediment, etc., is a new type of phosphating agent, it is suitable for automobile, motorcycle tricycle, agricultural vehicle industry and other steel parts before painting corrosion treatment.

1. It is a film pretreatment agent based on silane technology, widely used in surface treatment of steel, galvanized steel and aluminum substrate. 2. It can be used as an alternative to traditional zinc and iron phosphating. 3. Unique formulation technology is adopted to enhance the comprehensive performance of coatings of different coating processes. 4. It can be sprayed or soaked.

1. The film forming speed is fast, and the generated conversion film has strong adhesion to the coating. 2, do not contain phosphate, do not contain chromium, nickel, do not need promoter, room temperature operation, energy saving and environmental protection. 3. Significantly reduce the water consumption, reduce the amount of wastewater treatment, and the consumption is very low. 4. The original production line can be used directly without any transformation investment. 5, aluminum galvanized sheet slag free (cold rolled sheet micro slag), collinear treatment of a variety of metals (aluminum, galvanized sheet, copper), no need to regulate, no need to clean the nozzle and sediment settlement.

1. improve the impurities brought in by the previous step of pretreatment, especially the substances brought in by the parts with complex shapes.To improve the bad condition of workpiece caused by degreasing groove.It can also improve the bad effect of phosphorization caused by the precipitation of carbon from the workpiece surface due to pickling. 2. surface adjustment can make the film thickness of phosphating film in a stable state. 3. it can reduce the amount of residue in the phosphating solution. 4. reduce the consumption of phosphating solution. 5. reduce the consumption of accelerators. 6. reduce the phosphating process temperature. 7. to make the phosphating film oriented crystallization in a favorable direction.

1. Free from harmful hexavalent chromium and other harmful substances, it is a green product. 2. Suitable for all kinds of metal and after electroplating treatment, the anti-discoloration effect is good. 3, the formation of anti-discoloration film with hate water and welding function, drying without water stains. 4, after anti-discoloration treatment, the surface is smooth, no hand print. 5. Only produce extremely thin protective film on the surface of the workpiece, which can prevent discoloration economically.
