MIL-PRF-87937 is a United States military performance specification that establishes the requirements for biodegradable, water-dilutable, and environmentally safe cleaning compounds designed for use on aerospace equipment.
The compound is critical for routine maintenance and pre-treatment of military and civilian aircraft. It is formulated to be effective on various soils, including greases, oils, hydraulic fluids, and carbon exhaust, while ensuring compatibility with sensitive aircraft materials like painted aluminum surfaces, conversion coatings, and acrylic plastics (when used correctly).
The cleaning compounds meeting MIL-PRF-87937 are used on:
The MIL-PRF-87937 specification covers four distinct types of cleaning compound, classified by their chemical composition and intended duty level:
All types are designed to be biodegradable and water-dilutable to varying degrees. Users must adhere to specific dilution ratios and ensure the correct type is used for the coatings on the equipment (e.g., Type I may not be suitable for lacquer coatings).
MIL-PRF-87937 doesn't have a single common international NATO Code but is widely referenced by commercial aviation specifications due to its environmental focus and effectiveness.
It's crucial to consult the Qualified Products List (QPL-87937) for the latest approved products and the equipment manufacturer's Technical Orders for required dilution rates.
