The present study investigates the use of cationic UV curing for epoxy coatings combined with inhibitor-laden nanoparticles to improve corrosion protection. The aim was to analyse the effect of cerium-laden silicon dioxide nanoparticles (Ce-SiO₂) on the curing process and the coating properties. Reading tip: Functional CoatingsThe EC Tech Report “Functional Coatings” gives you an up-to-date bundle on functional coatings with articles, videos and other handpicked content. In addition to technical articles about the latest technical developments, this all-in-one multi-media pack is rounded off with valuable market insights and important fundamentals about functional coatings formulation. The nanoparticles apparently not only act as an inhibitor carrier, but also improve the physical barrier function of the coating.
