is a specialized consumable material primarily used in the aviation industry for protecting propeller components. It is frequently specified in service documents from Hartzell Propeller Inc. for the maintenance of steel counterweights. Application and Usage
For procurement, CM352 is often listed as a consumable part (PN: CM352) available through specialized aerospace suppliers like PB Aviation Parts . HC-SL-61-364 - SERVICE LETTER
: Regular re-application is recommended at scheduled intervals—often aligned with standard lubrication schedules—to ensure extended protection against environmental wear.
: While central to propeller maintenance, it is recognized as a general-purpose corrosion inhibitor by aviation parts vendors like PartsBase . Considerations
This guide covers formulation summary, properties, mechanisms, typical applications, surface prep, application methods for portable/field use, dosing, safety/handling, testing/verification, troubleshooting, storage, and regulatory/compatibility notes. Assumes CM352 is a packaged portable corrosion inhibitor product for metal protection in field/temporary service (if you need manufacturer-specific data or safety sheet, supply that or request a web search).
During standard structural inspections, technicians examine hidden interfaces where moisture accumulates. As directed by documents like Hartzell Alert Service Bulletin HC-ASB-61-376 , CM352 is the mandated treatment fluid for: Staking pins and localized staking pin holes. The vertical side walls of mounting bolt recesses.
Saltwater is a metal’s worst enemy. On a small fishing boat or a large cargo ship, space is a premium. Storing a 1-liter portable bottle of CM352 in a life raft locker or engine room allows quick treatment of corroded battery terminals, winch cables, and deck hardware during a voyage.
Beyond aviation, the properties of CM352 make it an excellent choice for protecting threaded connections, metal couplings, and structural components in chemical processing or heavy manufacturing. How to Apply CM352 for Maximum Protection
: Specifically formulated to prevent corrosion on bolt-on, steel counterweights. Long-Term Reliability
Avoid excessive pooling; the fluid's natural capillary action will pull it into tight clearances. Step 3: Inspection and Verification
The Corrosion Inhibitor CM352 Portable is a reliable and efficient solution for protecting metal surfaces from corrosion. Its portability, ease of use, and long-lasting protection make it an excellent choice for industries where corrosion is a significant concern. While it may have some limitations, the benefits far outweigh the drawbacks. Overall, I highly recommend the CM352 Portable to anyone seeking a convenient and effective corrosion inhibitor.
