AkzoNobel Aerospace Coatings has unveiled a single-coat Aerobase basecoat solution for MRO paint facilities.
The enhanced formulation replaces traditional two-coat application processes with a validated single-coat system, the aim being to reduce application time, process complexity and total film thickness whilst delivering a high-quality, consistent finish across mixed fleets.
The product has been certified for use within the global MRO mixed fleet market, enabling immediate deployment in operational paint facilities, and OEM testing and approval is set to follow.
The development programme focused on optimising application control, film build consistency and finish quality within performance-critical MRO environments.
AkzoNobel Aerospace Coatings said that the enhanced formulation delivers approximately 40% improved sag resistance compared to the original system. Combined with a cross-coat application process, it enables single-coat application whilst achieving the required hiding power and surface finish to replace the two-coat approach, the company added.
The company shared that field testing conducted in 2025 on a single-aisle aircraft demonstrated a 36% reduction in total film thickness compared to a previously applied two-coat system, without compromising durability or appearance.
“MROs are under constant pressure to improve efficiency without compromising quality,” said Aurore Bournazel, segment manager for OEM, MRO and airlines at AkzoNobel Aerospace Coatings. “This latest Aerobase development enables a validated single-coat process that simplifies application, improves consistency and delivers measurable performance benefits. By reducing total film thickness, it also supports airlines’ efforts to lower aircraft weight, helping to reduce operating costs and associated CO2 emissions.”
The enhanced Aerobase single-coat solution will be available in the most commonly used aerospace white colours.
AkzoNobel Aerospace Coatings’ technical teams are supporting MROs with process development, validation and applicator training. Additional aircraft applications are underway with two MROs, covering both single-aisle and wide-body aircraft.
The product is planned for global rollout throughout 2026.
