MIL-C-6529

MIL-C-6529 is a military specification (MIL-SPEC) established by the U.S. Department of Defense. This spec covers preservative compounds used as corrosion inhibitors for aircraft engines and components. These compounds are primarily used in aerospace applications to protect metal surfaces from corrosion during storage or idle periods. They are typically designed to protect from moisture, environmental conditions and other factors. They function as oil-based corrosion inhibitors, which leave a thin protective film on surfaces to prevent oxidation and rust formation. The first version of this spec, MIL-C-6529a was established in April 1953. The most recent version is MIL-C-6529c.
