Properties:
KR-604 is built with organophosphoric acid, polycarboxylic acid, carbon iron and copper corrosion inhibitor. It can effectively chelate and disperse calcium carbonate, calcium sulfate and calcium phosphate scales. KR-604 has good scale inhibition effect on steel & iron and copper. KR-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.
