Current vinylester based coatings employ styrene to achieve the desired balance of viscosity and final coating properties. The drive towards sustainability and minimizing environmental impact stimulates the replacement of potentially volatile components, namely styrene, with nonvolatile co-monomers that can be derived from renewable feedstocks. Existing coating formulations are optimized towards the use of cobalt catalysts and in hence this bilateral project will focus on iron based catalysts to ensure that the monomers are selected to be optimized from the outset with the next generation of curing catalysts. The scientific ambition of this project is to understand and match the reactivity of monomers through kinetic analysis with spectroscopy methods. This knowledge will enable creation of the next generation of styrene and cobalt free performance coatings.
