MIL-C-23411 Military Specification

What is MIL-C-23411?

MIL-C-23411 is a United States military specification that outlines the performance and technical requirements for transparent, thin-film corrosion-inhibiting compounds. This specification was developed to safeguard metal surfaces-particularly in the aerospace sector-against rust and oxidation. Products compliant with this standard provide reliable protection while ensuring compatibility and safety with a broad range of materials.

Key features of the MIL-C-23411 standard

Exceptional penetration capability

The compound can infiltrate fine gaps, joints, and hard-to-access areas, ensuring comprehensive coverage of the entire metal surface, including concealed spots. This deep penetration greatly reduces the likelihood of corrosion.

Effective rust removal and water repellency

Formulations meeting the standard can dissolve existing rust and prevent further formation. The resulting protective film is ultra-thin, transparent, and firmly bonded to the substrate, while resisting mild acids and alkaline solutions.

Compatibility with multiple materials

Safe for use on paint, plastics, rubber, and plated finishes-an essential quality in aerospace applications where diverse materials are in use. The coating can also be reapplied over existing layers without stripping them away, making maintenance faster and easier.

1	Krytox GPL 107		Krytox GPL 107 is a clear, fluorinated perfluoropolyether (PFPE) synthetic oil for long-term lubrication. Krytox GPL107 is completely non-flammable and non-reactive, making it ideal for extreme temperature applications.
2	Krytox GPL 205		Krytox GPL 205 is a white, synthetic grease made from perfluoropolyether (PFPE) and PTFE thickener, with many outstanding properties.
3	Krytox GPL 227		Krytox GPL 227 is a white PFPE grease that provides improved corrosion, rust and wear protection.

Applications of the MIL-C-23411 standard

Corrosion protection for aircraft surfaces and components

Provides durable protection for aircraft structures and mechanical parts exposed to extreme environments such as high humidity, marine conditions, and tropical climates. The transparent, thin coating preserves both aerodynamic performance and appearance, making it valuable for both military and civilian aviation.

Rust prevention during engine overhaul and storage

By applying a protective layer to parts that are out of operation or stored for extended periods, the standard helps preserve their original condition, reduce the need for replacements, and streamline routine maintenance.

Protection for tools, measuring instruments and industrial machinery

Prevents corrosion-related damage, ensuring precision, prolonging service life, and maintaining operational safety.

Temporary corrosion prevention during shipping and storage

Shields metal parts from oxygen and moisture exposure until they are assembled or put into service-an effective way to maintain quality during logistics and warehousing.
