Maastricht University’s role is to develop and characterise lignin-based resins for waterproofing coatings, using the depolymerised lignin fractions produced within SPLENDOR. The team will functionalise lignin through organic chemistry and design crosslinking strategies that enable recycling (so-called covalent adaptable networks). Alongside detailed chemical analysis, the material properties will be assessed through rheology, DMA, tensile testing, and related methods. The performance of the lignin-based resins in coating applications will also be evaluated, in close collaboration with SOPREMA.
