Transportation and ACE – Aircraft Coatings

Aircraft coatings fly high with polyurethane

Stable, flexible, durable coatings allow aviation vehicles to take off

Aircraft often face extreme temperature swings within short periods of time. As such, airplane coatings must be flexible enough to cope with thermal stress while also offering UV stability and reliable mechanical resistance. Polyurethane (PU) raw materials for coatings are a high-flying solution.

Durable coatings for aviation vehicles

From turboprop commuter planes to helicopters to jumbo jets, commercial aircraft experience intense conditions, having to withstand extreme UV and temperature exposure on a regular basis. Helicopters, whose hovering action kicks up stones and other debris, present their own unique durability requirements, while the exhaust and high temperatures generated by turbine-powered aircraft present even more challenges. But that’s not all: aircraft coatings must often comply with a wide range of industry and governmental specifications and requirements.


Given their flexibility, durability, mechanical resistance and overall performance, it’s no wonder PU resins for aircraft coatings are the first choice to meet those demands.

Covestro provides industry-leading resins and hardeners that can be added to primers, topcoats and clearcoats, enabling superior resistance to chemicals, corrosion and weather.

Aircraft are prepared for takeoff with water-based and solvent-based two-component (2K) polyurethane coatings formulated with our Desmodur® polyisocyanates. These airplane coatings demonstrate outstanding mechanical and chemical resistance, excellent UV-resistance, good elasticity, fast drying at room temperature and elevated temperatures, and compliance with volatile organic compound (VOC) regulations.
