Properties

DT-208B compounds the organic phosphonic acid, poly carboxylic acid, carbon steel corrosion inhibitors and copper corrosion inhibitor , primarily for the low hardness corrosion water ,to control corrosion of the circulating water mainly, taking into account resistance Scale effects . It has excellent Chelating dispersion effect on calcium carbonate in water, calcium sulfate, calcium phosphate, etc.DT-208B is mainly used for circulating cooling water system corrosion and scale inhibition , such as power plants, chemical plants, petrochemical, steel and other circulating cooling water systems, DT-208B has excellent scale and corrosion inhibition.
Specification DL/806-200
