Enter , a solution designed to bridge the gap between heavy industrial protection and on-the-go operational flexibility.
: In cases where existing corrosion is found during inspection, the protocol involves cleaning the surface with a solvent (like CM23) and an abrasive pad (CM47) before re-applying CM352 to restore protection.
Once applied, the compound forms a resilient barrier that seals the underlying metal from moisture, salt spray, and atmospheric oxygen.
CM352 is a corrosion-preventive compound mandated by for use on bolt-on, steel counterweights in aircraft propeller systems. According to Hartzell's Service Letter HC-SL-61-364, corrosion inhibitor CM352 is applied during the assembly process at the factory and must be periodically reapplied to ensure continued protection. corrosion inhibitor cm352 portable

: Periodic re-application provides a long-term shield, significantly delaying the need for expensive component replacements.
In essence, the compound serves as a durable barrier layer between the steel surface and the surrounding environment. It prevents moisture infiltration around fastener interfaces, spring pin wells, and bolt heads—areas where water entrapment is almost inevitable during aircraft operation and storage. Periodic re-application of corrosion inhibitor CM352 provides extended protection against rust and galvanic corrosion. Enter , a solution designed to bridge the
: Use only in well-ventilated areas. The material may be flammable; avoid open flames, sparks, or temperatures exceeding 50 raised to the composed with power C 122 raised to the composed with power F Inhalation : Move to fresh air immediately if symptoms develop. Skin Contact
It features low surface tension, allowing it to autonomously seep into microscopic crevices, thread engagement zones, and staking pin channels.
. While the inhibitor itself is a chemical compound, its application is a critical "portable" field maintenance task performed by technicians to prevent oxidation on exposed metal surfaces. Hartzell Propeller Application & Purpose Target Components CM352 is a corrosion-preventive compound mandated by for
It is specifically used on bolt-on steel counterweights, staking pins, and mounting bolt recesses.
recommends applying CM352 during assembly and suggests periodic re-application at regular lubrication intervals to ensure extended protection Hartzell Propeller Field Application Process
Applying a high-tier product like CM352 requires precision. Following a standardized process—derived from official Hartzell Propeller Alert Service Bulletins —guarantees optimal adhesion and longevity. 1. Initial Visual Inspection
When an aircraft undergoes a pre-flight or scheduled line inspection, technicians need tools that are lightweight and self-contained. Portable CM352 delivery systems—such as localized aerosol canisters, specialized touch-up pens, or compact handheld pump sprayers—allow mechanics to treat the propeller directly on the tarmac without removing the entire assembly from the engine crankshaft. 2. Preventing Rework Costs
According to official Hartzell Alert Service Bulletins , specific focal points must undergo visual inspection and manual application of CM352 during routine maintenance intervals:
