Spray 3K-WB primer coating with manual Airmix gun

Save up to 30% of paint, 25% of cycle time, and obtain high finishing quality with Sames Xcite®+ manual gun spraying combined with automatic mixing technology.

Discover our solution

In the demanding world of aerospace, precision and process control are non-negotiable. Sames offers a complete 3K (three-component) paint application solution, engineered specifically for aeronautic structures, where pot-life management, traceability, and flawless finish are critical.

Our solution features:

  • Flowmax® below pump technology for moisture-sensitive hardeners.

  • The Cyclomix® Evo 3K automatic mixing machine, which regulates pressure, manages mixing ratios in real time, and ensures consistent quality throughout the application.

  • Spraying with manual Airmix® Xcite®+ gun, combining outstanding finishing quality with high transfer efficiency and productivity — making it the go-to reference for demanding aeronautic coatings.

  • Semi-automatic flushing box, which automates flushing and mixing refresh cycles, keeping the mix age below the defined pot-life.

With the arrival of new chromium VI-free primers that feature shorter pot-life windows, automated 3K mixing is no longer optional — it’s essential.

The Cyclomix® Evo 3K also supports digital traceability and data logging, aligning with the aerospace industry's digitalization and quality assurance standards.

Aeronautic structure Solution FAQ

Let's get in touch

  • Can I spray epoxy-based primer and PU-based topcoat with the same equipment?

    No, it's not recommended to use the same mixing and spraying equipment for both epoxy primers and polyurethane topcoats due to chemical incompatibility between their hardeners. Separate circuits or strict equipment isolation must be considered to avoid cross-contamination and ensure finish quality.

    The Best Practice is to use fully separate dosing/mixing equipment (2K Cyclomix® Evo or equivalent), or at least separate paint circuits with manual or semi-automated switching and dedicated flushing routines. This is especially true in the aeronautic industry, where risk management and process traceability are held to the highest standards.
    In robotic application, if requested on the same robot, dual spray guns mounted on a robot (one for epoxy, one for PU) are often a more secure solution.
    Sames can assist you in designing safe, efficient multi-product solutions, based on your cycle time, quality constraints, and maintenance preferences. Contact us to evaluate the best configuration for your process.

  • Are there any special recommendations for spraying the new generation of chrome-free 3K primers?

    Yes, the transition to chromium-free 3K primers in the aeronautic industry brings new requirements for application processes. Historically, chromium-VI-based primers were retained in aerospace due to their exceptional corrosion protection, despite known health hazards. Their continued use was granted under strict derogations, given the criticality of aircraft structures and the lack of qualified alternatives. However, with validated chromium-free formulations now entering the market, the industry is actively shifting toward safer, environmentally compliant solutions.
    One of the key differences observed with these new primers is a shorter pot-life, which makes manual 3K mixing less reliable and more error-prone. As a result, automated 3K mixing systems (Cyclomix® Evo) are no longer just a best practice—they're becoming a necessity. These systems ensure precise component dosing, accurate pot-life management, and consistent application quality.
    Moreover, automated 3K solutions open the door to process digitalization, with features such as mixing traceability, VOC emission tracking, and production data logging, which are increasingly demanded in aeronautics for compliance and sustainability reporting.
    By adopting advanced automated mixing and spraying technologies, manufacturers can not only meet the technical needs of new-generation primers but also enhance process reliability, operator safety, and environmental performance
