The increasing demand for sustainable and efficient metal treatment processes has led to the rise of zirconium and titanium hexafluoride-based conversions. These methods are favored for their reduced environmental impact and operational cost-effectiveness. However, challenges remain in achieving optimal paint adhesion and corrosion resistance, particularly in the automotive industry where aluminum wheels are prevalent.
During the presentation at The 2024 First Aluminum Wheel Industry Coating Conference and the 3rd CITIC Dicastal Coatings and Painting Forum, our scientists explored the role of Addibond™ in addressing these challenges. Addibond™ enhances the performance of Zr/Ti conversions by improving paint adhesion and corrosion resistance, thus extending the service life and aesthetic retention of aluminum wheels.
Here are the key topics discussed:
- Overall comparison between Cr-based and Cr-free technologies (Ti,Zr): A comparative analysis, leading to the need to add promoters to Cr-free systems to fill performance gap with Cr-based technologies
- Addibond™ as a Game-Changer for Ti,Zr systems:
- An in-depth look at how Addibond™ polymers work, especially compared with conventional polyacrylates and silanes
- Performance data showcasing the significant performance boost provided by Addibond™ 829 to Cr-free systems, such as paint adhesion but also filiform corrosion resistance to name a few.
- Real-world application in the Aluminum wheel market: A comparative analysis, showing the benefits of Addibond™ 829 versus conventional polyacrylates and silanes on actual wheels
- Addibond™polymers next generation: Syensqo launched Addibond™ PF1, providing the same benefits as Addibond™ 829, while being P-free which guarantees a sustainable use in the context of increasing regulatory pressures on P-based chemicals, and makes it even easier to manage baths.
