The IMPOSSIBLE Project: A Journey of Transformation (Frank Brouwer, Stahl)
In a world increasingly divided on sustainability, reaching our goals can feel impossible. I found inspiration in the story of Polaroid and The Impossible Project. In 2008, Polaroid's shutdown shocked fans—but sparked a bold response. An innovator, fueled by passion, revived the technology through The Impossible Project. This tale offers lessons for the European coatings industry, showing how passion, innovation, and community can overcome obstacles. Frank Brouwer, Renewable Chemistry Specialist at Stahl, will explore these parallels. With over a decade at Stahl—a global leader in specialty coatings—Frank leads sustainable innovation. He'll discuss opportunities in renewable feedstocks, emissions reduction, and circularity. At Stahl, change is driven by passion and collaboration. Frank’s key goal is to inspire the coatings industry to write its own success story, mirroring the achievements of The Impossible Project. This transformative journey begins today. |

Excimer Matting: Controlling the gloss of aqueous coating compositions (Ilse van Casteren, Covestro)
Waterborne UV curable coatings are growing rapidly due to stricter VOC regulations and advances in fast, on-demand curing. Their high crosslinking provides excellent stain, solvent, and scratch resistance. There is increasing demand for low-gloss, high-performance finishes that maintain the natural look of substrates like wood. Silica-based matting agents are commonly used to reduce gloss but can cause issues like scratch and water sensitivity, and stress cracking on flexible substrates. To address these drawbacks, a self-matting, additive-free UV curable coating was developed. This paper presents a new curing approach combining a short-wave excimer lamp and a polychromatic mercury UV lamp, resulting in low-gloss, waterborne UV coatings with excellent mechanical and anti-stain properties. |

Bottom-up design of naturally sourced materials for coating applications (Jitte Flapper, AkzoNobel)
Aiming to move away from fossil sources, raw materials originating from natural sources are gaining more and more attention. The bottom-up design of these materials comes with a number of difficulties. Fossil materials have set the standard, and trying to match all properties of these known materials can be very challenging. In this presentation, recent approaches of bottom-up design of bio-sourced building-blocks will be presented. This shows the challenges accompanying this approach, such as uniformity of starting materials, achieving selective modification, and scale-up challenges. Some examples of incorporation of bio-based materials in commercial products will be presented as well. |

Science-based formulation of coatings via webapps (Sander van Loon, VLCI)
The predictive formulation science, Hansen Similarity Parameters (HSP) and Hydrophilic Lipophilic Difference (HLD), are powerful tools to match, replace and compatibilize ingredients, resulting in maximum product performance while minimizing development time. These models assign predictive parameters to a wide variety of ingredients, applicable in coatings, inks, personal and home care. Each parameter can be reused, drastically reducing experimental work, time and costs, enabling a more sustainable R&D workflow. VLCI established the world’s largest shared HSP and HLD dataset, linked to science-based formulation webapps for instant visualization and search. The collaborative platform allows sharing of parameters while protecting private data and IP. Ingredients can now be selected in minutes instead of months. Both theories and platforms will be presented, with examples of coating developments optimizing film formation, gloss, stability, barrier, etc. |
