is a specific corrosion inhibitor primarily used in the maintenance and assembly of Hartzell Propellers . It is classified as a "consumable material" in Hartzell technical documentation. Key Uses & Application
Refer to Figure 3. * Be sure the bolt heads, spring pins, and bolt wells are completely. covered with corrosion inhibitor CM352. * HC-SL-61-364 - SERVICE LETTER

Upon introduction into an aqueous system, CM352 rapidly migrates to the anode sites on the metal surface (where oxidation and metal loss occur). The polar heads of the inhibitor molecules adsorb onto the metal lattice, forming a durable, monomolecular film. This film increases the electrical resistance of the anode, effectively halting the dissolution of metal ions into the water. is a specific corrosion inhibitor primarily used in
For a new or cleaned system, use a "shock dose" of 2000–2500 ppm of CM352. Circulate this concentration for 24–48 hours. This step allows the film to fully develop on all bare metal surfaces.
Does not damage mechanical seals or pump packings. Safety & Handling * Be sure the bolt heads, spring pins,
Ensuring the system remains in the ideal alkaline range (typically 8.5 to 10.0 for ferrous systems).
Track total dissolved solids to manage blowdown schedules and prevent excessive corrosive ion buildup. Conclusion
Corrosion and scale often occur together. Under-deposit corrosion happens when minerals trap moisture against metal, forming deep pits. CM352 includes mild dispersants that prevent mineral scale from baking onto heat transfer surfaces, ensuring uniform chemical coverage. Key Benefits of Using CM352
