Corrosion Inhibitor

Low concentrations of non-toxic chemicals can be combined to provide an effective corrosion inhibitor for steel and other metals in water cooling systems.

Additions of silicates in combination with organic amines and organic acid salts reduce oxidation and scale formation on steel and copper and can be released into natural waters. The constituent concentrations can vary among the following ranges: Silicates 260-1500 ppm Amines 100-500 ppm Trisodium Citrate 100-500 ppm

Sodium silicate and sodium citrate when combined with an amine, such as triethanolamine, cyclohexylamine or morpholine, are particularly effective. Benzotriazole in trace quantities (2-10 ppm) can be added to protect copper components.
