It effectively protects iron and copper surfaces against corrosion. It forms positively charged colloids by bonding with calcium ions. Contains polymer to prevent precipitation of calcium phosphate. It is a corrosion inhibitor composed of polyphosphate, organic phosphate and azole compounds. It is used for conditioning closed circuit cooling waters. It effectively protects iron and copper surfaces against corrosion. It forms positively charged colloids by bonding with calcium ions. The positively charged colloids formed accumulate on the cathode surface and form a passive film. Contains polymer to prevent precipitation of calcium phosphate.
