TH-604 Scale and Corrosion Inhibitor for Power Plant

Properties:

TH-604 is built with organophosphoric acid, polycarboxylic acid, carbon iron and copper corrosion inhibitor. TH-604 can effectively chelate and disperse calcium carbonate, calcium sulfate and calcium phosphate scales. TH-604 has good scale inhibition effect on steel & iron and copper. TH-604 is mainly used in circulating cool water system in power plant, chemical plant, petrochemical, steel & iron. It has the advantages of effective and strong corrosion inhibition.
