Dr Toine Biemans, Manager Sustainability and Scientific Academic Partnerships at Worlée Chemie, discusses how consumer preferences impact bio-based coating development and how resin sustainability can be enhanced. How do consumer preferences for eco-friendly coatings impact bio-based coating R&D? So this potentially leads to a divergence of eco-friendly coating resin development: bio-based as well as low-PCF coating resins. Sustainable resin development can benefit from more such opportunities. One of the biggest needs is to replace fossil-based aromatic components such as phthalic anhydride with more sustainable, bio-based substances.
