Corrosion Inhibitor: Cm352

In closed chiller circuits and low-pressure heating systems, water is recirculated continuously. Over time, dissolved oxygen can cause severe pitting corrosion. CM352 is ideal for these environments because it does not readily degrade under continuous thermal cycling and provides years of protection with minimal replenishment. Oil and Gas Production

is a specialized aviation-grade protective compound designed to shield high-stress aircraft components from moisture, oxidation, and structural degradation. Listed as an essential consumable material in the Hartzell Propeller Standard Practices Manual 202A , CM352 is primarily used to safeguard propeller counterweights, mounting recesses, and critical hardware from environmental wear. cm352 corrosion inhibitor

CM352 corrosion inhibitor is a concentrated, liquid-based, multi-metal corrosion inhibitor designed for use in closed-loop systems, cooling towers, oilfield applications, and industrial processing units. Unlike generic inhibitors that protect only ferrous metals, CM352 is formulated to provide a protective barrier on a wide spectrum of metallurgies, including mild steel, copper, brass, aluminum, and galvanized surfaces. In closed chiller circuits and low-pressure heating systems,

Does not damage mechanical seals or pump packings. Safety & Handling Oil and Gas Production is a specialized aviation-grade

A: Indirectly. CM352 does not contain biocides, but the dense film prevents sulfate-reducing bacteria (SRB) from accessing the metal surface. For active MIC, treat with a biocide 24 hours before adding CM352.

| Problem | Likely Cause | Solution | | :--- | :--- | :--- | | High iron counts despite adequate dosage | Biofilm under-deposit corrosion | Conduct a biocide shock (non-oxidizing) and then re-passivate with CM352. | | Copper pitting | Low azole concentration | Test tolyltriazole levels; supplement with a dedicated copper inhibitor if below 10 ppm. | | White rust on aluminum | pH > 9.5 | Reduce alkalinity via acid feed (sulfuric or CO2). | | Foaming in cooling tower | Overdose >2000 ppm | Reduce feed rate; add a low-silicone antifoam. |

By preventing the degradation of close-tolerance components, it ensures that parts like propeller counterweights operate safely and reliably.
