Single-Coat Technology Targets Efficiency Gains in Aircraft Coatings
AkzoNobel Aerospace Coatings introduced a single-coat Aerobase basecoat solution designed to improve performance, efficiency and operational throughput in maintenance, repair and overhaul (MRO) paint facilities.
The formulation replaces traditional two-coat application processes with a validated single-coat system, reducing application time, process complexity and total film thickness while maintaining a consistent, high-quality finish across mixed fleets.
Developed for the global MRO mixed fleet market, the product is certified for immediate use worldwide, enabling facilities to adopt the single-coat process without delay.
The development program focused on optimizing application control, film build consistency and finish quality in performance-critical MRO environments. The enhanced formulation delivers approximately a 40% increase in sag resistance compared to the original system.
When used with a cross-coat application process, the system achieves the required hiding power and surface finish in a single coat, replacing the traditional two-coat approach.
Field testing conducted in 2025 on a single-aisle aircraft showed a 36% reduction in total film thickness compared to a previously applied two-coat system. The reduction was achieved without compromising durability or appearance, supporting both productivity and finish quality.
The reduced film thickness also contributes to lower operating weight, which can support reduced fuel consumption and associated CO₂ emissions for airlines.
“MROs are under constant pressure to improve efficiency without compromising quality,” said Aurore Bournazel, segment manager OEM, MRO and airlines. “This latest Aerobase development enables a validated single-coat process that simplifies application, improves consistency and delivers measurable performance benefits.”
The solution will be available in commonly used aerospace white colors, supporting immediate adoption by airlines and MRO operators. Technical teams are supporting facilities with process development, validation and applicator training to ensure consistent results.
Additional aircraft applications are underway with two MROs, including both single-aisle and wide-body aircraft. These trials are expected to provide further real-world performance data to support evaluation of efficiency, weight reduction and finish quality.
The product is certified for global use in the MRO mixed fleet market, with OEM testing and approval planned. A global rollout is expected throughout 2026.
