Cm352 Corrosion Inhibitor Exclusive
According to Hartzell Service Letter HC-SL-61-364 , steel counterweights are pre-coated with CM352 during the factory assembly process. Because these weights control blade pitch angle, surface rust can alter their balance or cause stress-corrosion cracking over time. 2. Recess and Pin Maintenance
At optimum concentration (50–200 ppm), surface coverage (θ) exceeds 0.95, reducing both H⁺ reduction (cathodic) and Fe dissolution (anodic). cm352 corrosion inhibitor
is a specialized aviation-grade protective compound designed to safeguard critical aircraft components against rust, oxidation, and structural degradation. Formulated to meet rigorous aerospace standards, this consumable material is most notably recognized as a mandatory maintenance fluid specified in the Hartzell Propeller Standard Practices Manual 202A . Corrosion poses a massive financial and safety risk to aircraft operations. Using targeted chemical inhibitors like CM352 ensures that highly stressed metals remain structurally sound throughout their operating lifecycle. What is CM352 Corrosion Inhibitor?

CM352 addresses this issue by functioning as a surface-passivating film barrier. This barrier halts the electrochemical oxidation process that degrades steel.
Service bulletins like HC-ASB-61-376 require visual checks of critical hardware channels. Maintenance teams must clean the following areas and coat them with CM352: and staking pin holes. Mounting bolt recesses and their adjacent side walls.
It provides versatile protection across various metallurgy types, including carbon steel, low-alloy steels, and yellow metals. Best Practices for Application and Monitoring
