At present, middle and high temperature phosphate products and crafts are widely adopted in metal processing, automobiles, home appliances and railway, which has the faults of inconvenience, huge power consumption, uneven phosphating film and high cost. 

The low-temperature phosphate products feature stable performance, easy operation and adjustment, energy-saving, low cost, the phosphating film is compact, even with good adhesion and corrosion resistance. The low temperature phosphating solution is used in temperature of 25℃～35℃ to replace the traditional high temperature phosphate products, which are used 50℃～60℃.
