Copper Corrosion Inhibitor
Copper Corrosion Inhibitor
Copper Corrosion Inhibitor is a special passivation additive designed to protect copper, brass and other non‑ferrous alloys. It effectively suppresses discoloration and corrosion caused by sulfur‑containing extreme‑pressure agents in metal‑working fluid systems.
It exhibits good solubility in mineral base oils. This additive can be compounded with sulfur‑based EP additives to reduce copper corrosion risk, and maintains stable performance under typical metal‑working operating conditions. Good compatibility with common rust inhibitors and anti‑wear additives.
