is a specialized corrosion inhibitor primarily used in the maintenance and assembly of aviation propellers , most notably those manufactured by Hartzell Propeller Inc.
Advantages vs. legacy inhibitors
It sat in her satchel: . A milky, unassuming liquid. Most corrosion inhibitors were band-aids—films that tried to block chlorides from the outside. But CM352 was different. It was a migrating inhibitor. It didn't just sit on the surface; it walked. Like water seeking a crack, its molecules traveled through the concrete’s microscopic pores until they found the steel.
All new propellers manufactured after April 2020 feature counterweights pre-coated with CM352 during the assembly process. Routine Inspection: cm352 corrosion inhibitor
CM352 is formulated to handle exactly that.
This broad compatibility makes CM352 the preferred choice for mixed-material assemblies, such as automotive engines or hydraulic systems. It is referenced under the Consumable Materials chapter
