Azoles are yellow metal corrosion inhibitors that will protect copper and copper alloys. These additives also inhibit galvanic corrosion of ferrous metal surfaces, by preventing the deposition of copper onto the ferrous metal.

Copper and copper alloy corrosion will accelerate the deterioration of piping systems, with detrimental effects on the overall efficiency of the closed loop operation. By controlling yellow metal corrosion, damage to steel will be prevented. Inhibited ethyelene glycol or propylene glycol containing azoles are ideally suited for  use in mixed metallurgy systems. Azole concentrates can also be added separately to a closed loop system.

Features & Benefits

  • Corrosion inhibitors for copper, admiralty brass, and other copper alloys
  • Inhibitors that form a protective film on the metal surface thereby preventing copper plating.
