Hydroxy-ethylenediphosphonic acid is a new type of chlorine-free electroplating complexing agent, which is used as the main agent for water quality stability in circulating cooling water system and plays the role of corrosion inhibition and scale inhibition.Hydroxyethylenediphosphonic acid is a kind of cathodic corrosion inhibitor and a kind of non-chemical equivalent scale inhibitor. When combined with other water treatment agents, it shows an ideal synergistic effect.
Usually packed in 200kg/drum, and also can be do customized package.
