Aerospace coatings for aerospace coatings types:

A North American company developed automatic bottom surface layering, polyurethane coatings, the coating meets or exceeds the standard epoxy primer and polyurethane topcoat a supporting system of performance requirements, applied to the phosphating treatment of aluminum surfaces have been well received. Paint without lead and chromium, in line with environmental requirements, substantially reducing the coating workload and solvent emissions, can be made of camouflage gloss to high gloss.

A U.S. company developed a single-liquid-type curing with polyurethane primer, the film can be bent with the vibration of the aircraft to prevent close to the rivets and other high-stress parts of the coating cracking, even if even if the topcoat layer may be damaged, the primer layer can continue to protect the substrate. The primer has been applied to most of the U.S. military aircraft. A European coatings company has developed a high solids epoxy topcoat for aircraft interiors that has been approved by McDonnell Douglas and Boeing. The epoxy polyurethane primer also meets some national naval standards.

Specialty epoxy coatings are used to protect critical aircraft components such as landing gear, magnesium gearboxes and heat exchangers. A special application is the air intake of jet engines in marine environments. Improved epoxy coatings are now available to meet environmental requirements. Titanium steel is used as a new material for high-temperature aero-engines, but it has not been put into use because of the corrosion form of "α-disease". A U.S. company's a can work at 800 ℃ coating significantly reduce this corrosion. Composite materials have been used in large quantities in the aviation industry, such as vertical take-off and landing helicopter wings as epoxy fiberglass, as well as carbon fiber high temperature engine block.
