Industry snapshot from the perspective of a leading pigment manufacturer
Stefan Suetterlin | Vice President Business Management of BASF Colors & Effects GmbH
Amidst many global challenges, such as a deteriorating economical climate, increasing trade barriers and general inter-regional tensions, profitability pressure has an ever stronger effect on the entire colour value chain. As a consequence, the coloured and effect pigment industry landscape is changing. In this presentation, one of the leading pigment manufacturers will share its thoughts on the background for these changes and how challenges will develop during this transformation process and what implications might result.
A view on pigments from Wall Street
Frank J. Mitsch | Senior Managing Director of Fermium Research
After a horrific 2018, the pigment suppliers’ equities have rebounded year-to-date with Tronox’s acquisition of Cristal (finally) yet to fully play out in the industry. Furthermore, uncertainties over demand, market stabilization pricing, Chinese supply, etc. have weighed on the sector. Higher level, chemical equities as a whole have been mixed and materially impacted by geopolitical issues, commodity pricing, weather, etc.
- Review historical swings in results and equity performance for pigments, downstream coatings companies and the chemicals industry
- Detail the changing landscape and the associated shift in producers’ approach to more rational pricing behaviour
- Explain the interplay of feedstocks for producers and highlight the benefits of vertical integration
- Examine company specific factors that have weighed on/propelled equity prices
- State the current views from Wall Street and expectations for future share price performance
What could the classification of TiO2 mean for your business?
David Lockley | Product Defence and Toxicology Manager of Venator Materials Plc. and of Chair of TDMA Scientific Committee
The proposed classification by the European Commission has been the most discussed classification file ever and despite significant concerns raised by many Member States, the Commission seems determined to move forward. The classification of TiO2 as a potential carcinogen could impact many downstream applications and severely effect the recyclability of many products preventing the Commission from meeting its own circular economy targets. The Titanium Dioxide Manufacturers Association (TDMA) have complete confidence in the safety of TiO2 and the group is investing Euro 14 Million to address any uncertainties that the Commission may have. This presentation shares where we are to date with the classification proposal and potential timeline and explores possible downstream implications should the proposal move ahead.

Colour Engineering: from nature to pigment applications
Dr. Silvia Vignolini | University Reader in Chemistry and Biomaterials, Department of Chemistry of University of Cambridge
The most brilliant colours in nature are obtained by structuring transparent materials on the scale of the wavelength of visible light. In this seminar, I will introduce some striking example of natural photonic structures in nature and review our recent advances to fabricate bio-mimetic pigments using the same material as nature: Cellulose. The control of cellulose-based architectures enables us to fabricate novel photonic pigments using low-cost materials in ambient conditions.

Recent developments in the field of pearlescent pigments
Carsten Plüg | Global Head Innovation & Application, Performance Materials – Surface Solutions of Merck KGaA
Pearleascent effect pigments are the dominating innovation driver in automotive colors. There is still need for pigments with unique effects allowing to create new looks. Apart from only decorative requirements, technical requirements like interaction with radiation, compatibility in thin layers and particle orientation differences in various paint systems haves gained increasing importance.
This paper provides an overview of recent developments of pearl pigments addressing market need, particularly in automotive paints and related areas.
Looking into the red/orange colour space-a new inorganic pigment class to fill the gap
Alexander Belkin | Product Manager/Business Development of Heubach GmbH
While organic pigments are well-known for its brilliance and tinting strength, inorganic pigments are considered to be very stable and hiding, but featuring a lower chroma.
Especially in the orange/red area there is a remarkable gap in the colour space in between organic and inorganic single pigment solutions as well as the toxic Molybdate Reds. Some efforts have been done in recent years to close this gap, e.g. more chromatic iron oxide grades or TinZincRutile Pigments (PO 82 / PY 216), however the gap is still there.
New series of high-performance silver dollar pigments (UTPs)
Dr. Frank J. Maile | Global Technical Director of SCHLENK Metallic Pigments GmbH
A novel series of silver dollar effect pigments deliver outstanding gloss properties combined with superior hiding power and flop. Combination of these pigments delivers unlimited texture designs. The new pigments also interact perfectly with the ultra-thin, aluminum-based pearl pigments (UTMs®): Fine graduation of color shades between silver and the corresponding metal based pearlescent pigment can be achieved without any disruptive change of color saturation. Champagne and beige color tones can be formulated with impressive flop and chroma. A new milling technology (UTM® Ultra Treated Metallics) is the basis for the unique performance of these pigments. Particle size distribution, thickness, and scattering are carefully controlled. The new silver dollar pigments are available in balanced particle sizes to cover most important applications i.e. rim wheel coatings, consumer electronics, household appliances, and automotive interior.
Quantitative characterisation of coatings using optical coherence tomography
Prof. Yaochun Shen | Department of Electrical Engineering and Electronics of University of Liverpool
The purpose of applying paint coating to automotive bodies is not only corrosion protection but also aesthetic enhancement. The majority of modern automotive paint systems consist of four layers: electro-coat, primer coat, base coat and clear coat. The base coat layer consists of a mixture of primary colouring pigment and metallic or mica flakes which are compressed into a base coat binder formulated either of acrylic or polyester polymers. The number, size and orientation of small metallic flakes in the base coat of the paint has a significant effect on the appearance of automotive bodies. In this talk, I will present our preliminary work on non-destructive analysis of automotive paints by using optical coherence tomography (OCT) together with three-dimensional segmentation algorithms.

New colour sensor technology revolutionizes coatings market
Eric Kirchner | Senior Color Scientist of AkzoNobel
Color is a key selling point in many industries, the coatings market being a prime example of this. Therefore color is an important quality aspect in design, production and sales processes. In the past decade, several instruments for measuring color entered the market at prices 10 - 100 times lower than ever before. I will show why these low-cost instruments became technically possible only now, and discuss their accuracy. What customers and which processes can be supported with these instruments, and what will be their effect on the coatings market?
Characterization of interference pigments
Werner Rudolph Cramer | Researcher and journalist of Independent
Interference pigments belong to a popular group of pigments. And they are used in many applications. Since they have a different property profile than colour pigments, their characterization and identification does not seem easy. Interference pigments are individualists, i.e. each interference pigment has unique optical properties that set it apart from others. A particular feature of colourful interference pigments is the shift of the reflection maximum to shorter wavelengths when they are illuminated flatter. At the same time the reflection increases. White interference pigments and aluminium pigments do not show this shift, their reflection also increases when they are illuminated flatter. A colourful interference pigment can be best described by its interference and aspecular line: The interference line is formed from a*b* values for steep, classic and flat illumination at the same difference angle of gloss (aspecular). Due to the aforementioned reflection shift, the interference line always points in the direction of flat illumination counterclockwise. The aspecular line is formed from the a*b* values resulting from measurements at fixed illumination angle. Here, the difference angle (aspecular) is changed off gloss. The anchor shape resulting from both lines is characteristic of each interference pigment. Close to the gloss, interference pigments are best characterized. Even in blends with colour pigments, they maintain their optical properties close to the gloss. Based on this, the idea arose to place a coordinate system in 45°/as15° for further characterization. Furthermore, the sub-arms, the ratio of their lengths and the angles give a precise definition of each interference pigment. A total of six parameters characterize an interference pigment or aluminium pigment. This method has been successfully tested on databases with many patterns. Firstly, a query of a chosen pigment was started. From the previously calculated parameters, a range of values was formed, and then conversely six queries were performed. The hit rates were very high. By examples, this new method will be presented.

Pearlescent effect pigments from a different viewing angle
Tom Landuydt | Head of Industry Management Automotive Coatings of BASF Colors & Effects GmbH
Usually pigment manufacturers tend to highlight the unique visual properties of their new effect pigments. However, there is more to it than just ‘colours and effects’. This presentation attempts to change the viewing angle and highlight the ethical and ecological sustainability considerations for the use of natural and synthetic mica based pigments. Moreover, with the development of new technologies such as autonomous driving, a shift from a purely colouristic view towards a more functional profile for pearlescent effect pigments, might become necessary.
Natural coloured lipstick: A technology limitation has been overcome
Véronique Guyot-Ferréol | R&D Manager Senior of Sensient Cosmetic Technologies
The current consumer trends in the colour cosmetics industry are mainly focused on clean label, traceability and transparency, environmental and societal sustainability. Consumers consider natural ingredients healthier. Now naturality is not yet a trend, it becomes a fundamental requirement. Since many years, cosmetic industry moved successfully on this trend for a wide range of cosmetic products except for lipstick applications. Many issues appear as low coverage, difficult processing, weak stability, a narrow shade range … Thanks to a new generation of natural extracts in powder form, based on vegetable juices, Sensient Cosmetic Technologies allows to create lipsticks which comply.

Fireside chat: The science of paintings: lighting, pigments and perception
Prof. Dr. Gerhard Pfaff | Professor for Inorganic Chemistry and Expert in Pigment Research of Technical University of Darmstadt and Merck KGaA and Dr. Frank J. Maile | Global Technical Director of SCHLENK Metallic Pigments GmbH
Thanks to sophisticated scientific characterization techniques for materials of all kind, it is nowadays also possible to identify exactly the components of ancient and contemporary paintings including the pigments used. Another aspect is the investigation and consideration of paintings under varying illumination, which was further enhanced by the development of modern light sources.
Besides selected aspects of analytical methods and material science with regard to pigments and paintings, the dialogue will cover further related subjects, such as the illumination of paintings using modern LEDs and its impact on the perception of paintings.
