All three compounds must be allowed to cure for a minimum of three hours before flight. This coordinated approach ensures that each component surface receives the appropriate protection—sealants for voids, inhibitors for steel surfaces, and barriers for interfaces.
CM-352 is a water-displacing, thin-film corrosion inhibitor. The designation usually refers to aerosol cans or small manual sprayers for field maintenance.
The versatility of the CM352 Portable makes it invaluable across several sectors: corrosion inhibitor cm352 portable
apply CM352 to ice protection system components, such as de-ice boots, terminal strips, or harnesses, as it may degrade these materials. Hartzell Propeller Safety and Handling
Specifically designated to coat bolt-on, steel counterweights and surrounding components (like staking pins and mounting recesses) on aircraft propellers. All three compounds must be allowed to cure
Proper application increases the reliability of the propeller system, extends the lifespan of the counterweights, and reduces overall maintenance costs by preventing the need for costly parts replacement. Where to Find
When performing a periodic counterweight inspection or executing an Alert Service Bulletin, applying CM352 requires careful surface preparation to ensure proper adhesion. The designation usually refers to aerosol cans or
: Periodic re-application provides a long-term shield, significantly delaying the need for expensive component replacements.
The inhibitor works effectively on various metal substrates, including steel, aluminum, copper, and iron.
Propeller counterweights are heavy steel or metal components bolted or pinned directly to the root of the propeller blades. They utilize centrifugal force to change the blade pitch angle during flight, ensuring optimal engine RPM and thrust. Because they sit outside the protected hub assembly, they are continuously subjected to extreme conditions: High-velocity airflow. High centrifugal forces. Impacts from rain, dust, and gravel.
