I’m currently working on...

Unravelling the micro- and meso-structure of our polyurethanes and its supramolecular aspects – ranging from the raw materials and the synthesis process to the formation of polyurethane particles in water, and subsequently to the final coating properties by coalescence of these particles.

The aspect of my work that excites and inspires me the most is...

Creating value and profit for DSM by translating our long-term business needs into corresponding competence programs and new concept projects. In this way, new tools are created to achieve differentiating properties that are applied in attractive product developments for our customers. This results in continuous innovation of our product portfolio in order to outperform our competition. It is a fascinating journey and never a dull moment.

The breakthrough I would most like to see made in my field is...

To beat the statistics! Because all polymers intrinsically exhibit both a molecular weight and chemical composition distribution, I would like to have total control over building block sequences in the polymer backbone, as well as the ability to steer the self-arrangement of the polymer chains forming aqueous polymer particles and a homogeneous coating.

Key areas of expertise:

  • Polyurethane chemistry and technology
  • Hybrid technologies, such as urethane-acrylics
  • Polymer chemistry
  • Special design of polymer intermediates as unique building blocks
  • Coatings
  • Surface textures from very smooth to rough
  • Sequence control and catalysis of polyurethanes
  • Crosslinking of polyurethanes (ambient temperatures and UV-curable)
  • Aqueous dispersion technology and polymer particles
  • Modeling and design of experiments
  • M.Sc. Polymer Chemistry, University of Eindhoven

I represent DSM externally at:

  • Dutch Polymer Institute - Member of the Program Committee of the Coating cluster
  • NWO-subsidized public-private partnership with Technical University of Eindhoven, University of Utrecht, SymoChem, Institute for Complex Molecular Systems Synthesis: Self-assembly and stability of sequence controlled polyurethanes in water

Based in:

Waalwijk, the Netherlands
