Properties:
Corrosion Inhibitor for Closed Circulating System is used as corrosion inhibitor for closed system, such as the cooling water system and hot water circulation system in which glycol, methanol and ethanol are cooling media. It can be also used as corrosion inhibitor in anti-freeze fluid, oil tanker central air-condition system. Corrosion Inhibitor for Closed Circulating System is composed of organic corrosion inhibitor, dispersant, nitrite and molybdate. It is the most used corrosion inhibitor in closed system with excellent efficiency. It has good corrosion inhibition effect for carbon steel, stainless steel, copper alloy, aluminum alloy and other materials. There are no chromate in this product, thus no color will be occurred in water system and no stain spot will be deposited on metal surface. The liquid product is convenient in operation, suitable for closed circulating cooling water system with less or no leakage.
