3.1- Biorozon, the profitable future of biobased aromatics.
J.L (Joop) Groen, TNO
Biorizon is a Shared Research Program with an initial focus on technology development for the production of functionalized biobased aromatics for performance materials, chemicals & coatings. Biorizon is anticipating the expected growing shortage of aromatics from the petrochemical industry and the widely shared ambition to green the chemical industry.
Setting up a sustainable and economically successful commercial scale business, is a major challenge in this field. Biorizon is operated as a Shared Research Center, based on the open innovation methodology, bringing together collective intelligence of various industries, companies and knowledge organizations.
In this presentation the focus will be on the technology developments in Biorizon program line 3: sugars to aromatics. Due to the technology a wide variety of (specialty) aromatics can be produced. Biorizon is currently in the process of scaling up the first process from lab scale to bench scale (mini-pilot).
3.2- Thinking in biobased Solutions: Reality or challenge to meet
with regulations?
NicoFeima, Van WijheVerf B.V., Zwolle
In 2013 a target was set for the Dutch market by the VVVF to achieve a percentage of 50% biobased raw materials in all paints in 2030. To achieve this target a definition of biobased was formulated by the VVVF. As a ‘green orientated’ family company, Van WijheVerf set its own targets for the percentages of biobased raw materials they want to use in their products.
As the target was set for the entire paint industry (hence not only the deco, but also the automotive, industry and protective and marine coatings) questions rise if the target is feasible. This presentation will give an overview of definitions, results and calculations of feasibility and look at different regulations in Europe trying to find an answer to the question whether the target is a realistic challenge or too optimistic.
3.3- The future of wood as a substrate in outdoor applications,
especially joinery.
NielsLutke-Schipholt, SHR, Wageningen
Wood is a common material in outdoor applications such as decking, fences, constructions, cladding and joinery. For us as coating technologists probably the stable wood applications are the most challenging. Demands for extended warranty, longer service life, less maintenance, durability and performance in a zero emission facade, are dominant in the competition with aluminium and plastic alternatives to wood. This presentation will give an outlook on the major threats that are currently lowering the market potential for timber and efforts we see to be made by timber and coating industry collaborately to assure a sound perspective for stable wood applications in the future, resulting in highly competitive solutions compared to alternative substrate materials
3.4-The real choice for environmental friendlier paint.
Andre van Linden, AkzoNobel Decorative Paints, Sassenheim
As a supplier Akzonobel Decorative Paints listens to the customer’s wishes first. The real choice between solventborne or waterborne is made by the customer on a product level and not on a technology level. The customer is interested in anything environmental friendly as long as the product is great as well. This immediately creates the situation in which we find ourselves today and it raises the question in front of us. Will waterborne ever be able to replace solventborne products in all its aspects? Of course the answer is much more subtle than a simple yes or no. A number of recent innovations will be explained in this context. Legislative pressure exists for waterborne as well as for solventborne and creates another technology challenge (with all opportunities of it) for paint researchers. One of the most important challenges however is the way we communicate about the differences and extra opportunities.

3.5- New developments in alkyd resin technology for decorative
coating.
Dr. Dirk Mestach, Nuplex Resins BV, Bergen op Zoom
Air-drying alkyd resins form the basis of a rich palette of resin systems, each with its own special properties. Coatings based on alkyd resins have always been characterized by ease of application and high performance. Over the last decades, the use of alkyd resins has come under continued environmental pressure, but so far resin chemists have been able to tackle these issues quite effectively.
Recently renewed interest in alkyd technology also has been triggered by the increasing demand for paint binders based on renewable raw materials.
In this paper two new developments will be highlighted that combine state-of-the art performance with a high level of sustainability.
3.6- True Solvent Free (TSoF): Towards the next generation
waterborne coatings.

The market introduction of waterborne borne coatings in the past decades was a major step forward in the reduction of VOCs. Nevertheless, such waterborne coatings still contain significant amounts of organic solvents for softening polymeric particles (latex particles) and promoting film formation, next to their additional role for viscosifiers and anti-freeze. A potential breakthrough solution is to use water as a plasticizer itself, the so-called hydro-plasticization. Therefore, the polymer phase should be able to bind water. Nuclear Magnetic Resonance (NMR) and Diffusing Wave Spectrometry (DWS) are non-invasive tools that can be used to study water distributions and polymer mobility in a drying latex film. We will present a brief overview on how these tools have been used for similar studies in the past. Moreover, we will present how we plan to use these tools for our own research in the future.
3.7- Limit Values for VOC Emissions from Decorative Products
around the Globe
Caroline Laffargue, Vincent Van de Merckt, Reinhard C. Oppl,
Eurofins Product Testing A/S, Galten, Denmark.
Volatile Organic Compound (VOC) emissions from construction products and decorative products can contribute to indoor air pollution for some time period after the completion of building construction. Several low VOC rating systems contain restrictions on VOC emissions into indoor air but the limit values differ, and some of the testing and modeling parameters are not harmonized. An analysis of the most often used low VOC specifications shows both obstacles and opportunities for harmonization. The new European testing methods EN 16402 and CEN/TS 16516 help bringing together testing requirements within Europe. The new version of LEED allows showing compliance with its specification of low emitting interior materials not only with US-based testing methods, but now also with European test data.
This overview can help specifiers and regulators to establish meaningful low VOC requirements without re-inventing the wheel. And it can help manufacturers to save significant costs by combining tests for several purposes into one single test setup.
3.8- Status of biosourced and renewable raw materials for paint
industry.
MH.Delvaux - M.Wenkin- C. Lefèvre.
Coatings Research Institute, Limelette (Belgium)
In the field of paints, the use of bio-based products creates challenges. Indeed, the industry must take care of firstly, a limited range of bio-based products presenting a profile being satisfactory in terms of quality, cost and availability and, secondly, a lack of information on these products. The aim of this communication is to establish the actual status of the incorporation of already existing bio-based and renewable products in the formulations of paints. This presentation will address the key drivers for success in the use of these raw materials in paint formulation: cost, reproducibility, indoor air quality, durability and performance as well as life cycle analyses. The issue of the ecological quality of paint which is characterized by all the environmental impact of the product throughout is life will then covered. And finally the main parameters affecting the ecological quality of a paint will be argued. The conclusion will focus on the very promising future of these bio-based raw materials in the field of paints and varnishes.
