Cm352 Corrosion Inhibitor [exclusive] Jun 2026

CM352 is designed to be a , not a standalone finish coat (though it can be used as a temporary protective coat for months indoors).

Safe for use on metal surfaces but must be kept away from ice protection system components such as de-ice boots and terminal strips to avoid material damage.

| Feature | Rating | Notes | | :--- | :--- | :--- | | | ★★★★★ | Excellent at turning active rust into a stable surface. | | Adhesion | ★★★★☆ | Bonds well to tight rust; acts as an excellent primer. | | Ease of Use | ★★★★☆ | Water-based, low odor, easy cleanup. | | Durability | ★★★★☆ | Provides long-term protection when top-coated. | | Value | ★★★★☆ | Saves significant labor costs on surface prep. | cm352 corrosion inhibitor

CM352 is a chemical compound categorized as an additive or coating designed to decrease the corrosion rate of metal surfaces. In aviation specifically, it is a "locally procured" consumable material used during the assembly and maintenance of bolt-on steel counterweights for propellers. Its primary function is to create a passivation barrier between the metal surface and corrosive environmental agents like humidity, salt, and oxygen. Primary Applications

Ensure complete coverage of the pins to prevent moisture ingress. CM352 is designed to be a , not

It is specifically formulated to be used around sensitive components, though caution is always advised to keep it away from ice protection systems like terminal strips or boots.

Elara knew what it was. CM352 was a strange hybrid: a corrosion inhibitor originally developed for reinforced concrete bridges, later adapted for archaeology. It wasn't just a sealant. It was a chelation agent with a specific electrochemical trick—it targeted free chlorides while bonding to the ferrous surface at a molecular level, forming a hydrophobic film only a few nanometers thick. | | Adhesion | ★★★★☆ | Bonds well

Optional application is permitted for all other exposed metal surfaces of the counterweight.

By dawn, a miracle arrived. Not a shiny new sword—she would have wept if it were. That would be a lie. What arrived was a dark, bruised gray, like storm clouds over the Mediterranean. But it was stable . When she gently brushed a fiber probe across the edge, it didn’t crumble. It sang a low, metallic hum.
