Molybdate and phosphonate based corrosion inhibitor for cooling water system. We are manufacturer and supplier of this special type of corrosion inhibitor which acts as Filming Agent to protect metal surface from corrosion and its chemical reaction also help to prevent formation of calcium phosphate deposition.

RXSOL-40-4018 is a superior molybdate/phosphonate based corrosion inhibitor developed for use in closed cooling water systems. RXSOL-40-4018 prevents corrosion and deposits in closed and aerated cooling water systems. RXSOL-40-4018 contains inhibitors for steel, copper and copper alloys in combination with dispersants. RXSOL-40-4018 keeps the surface of the cooling systems clean and provides thus the basis for the formation of an effective corrosion protection film. 

Sodium molybdate has the advantage in that the dosing of lower ppm’s of molybdate allow for lower conductivity of the circulating water. Sodium molybdate at levels of 50-100 ppm offer the same levels of corrosion inhibition that sodium nitrite at levels of 800+ ppm. By utilizing lower concentrations of sodium molybdate, conductivity is kept at a minimum and thus galvanic corrosion potentials are decreased.

Technical Bulletin

RXSOL-40-4018 is a superior molybdate/phosphonate based corrosion inhibitor developed for use in closed cooling water systems. RXSOL-40-4018 prevents corrosion and deposits in closed and aerated cooling water systems. RXSOL-40-4018 contains inhibitors for steel, copper and copper alloys in combination with dispersants. RXSOL-40-4018 keeps the surface of the cooling systems clean and provides thus the basis for the formation of an effective corrosion protection film. RXSOL-40-4018 is mainly applied in secondary cooling water systems of power plants, in the cooling systems of blast furnaces, in systems for cooling the molds in continuous casting mills and in hot and cold water systems in the chemical industry. The program should be used with soft water, to avoid calcium phosphate deposition when the water losses are important.

RXSOL-40-4018 is added neat or diluted to the cooling water. RXSOL-40-4018 can be mixed with water in any ratio. Dosage requirements – The dosage rate is dependent on the system conditions and the amount of water lost from the system. Systems should maintain 400 ppm – 1000ppm of product in the water, while systems with high water losses should maintain ca. 1500 ppm in the system.
