Qianshi Surface Treatment Materials (Shanghai) Co., Ltd. was established in 2007, with its production base located in Caojing Town, Jinshan Chemical Industrial Park, Shanghai. Qianshi Company specializes in the production of various metal surface treatment materials. Our zinc based liquid surface modifiers, liquid manganese based surface modifiers, titanium based modifiers (zinc based surface modifiers), manganese based surface modifiers, and other surface modifiers for metal surface treatment phosphating solutions are produced using German technology formulas and high-quality imported raw materials. Compared with other surface modifiers on the market, one of the major advantages of our products is that the phosphating coating speed is particularly fast. Under normal circumstances, after using Qianshi surface modifiers (surface modifiers), the phosphating can be completely coated in 30 seconds, and it has excellent corrosion resistance in three minutes.
