Cerium oxide (Ceria) nano particle, as photodegradation prevention agent was studied in water-based polyurethane clear coat systems. Polyurethane coatings show superior weathering resistance compared with acrylic melamine systems. However, any chemical change has detrimental effects on the property profile of PU coatings. Coatings containing various amounts of cerium oxide nanoparticles were prepared and their weathering resistance was evaluated using simulated UV cabinet. To this end the extent and mechanism of degradation was studied utilizing UV-Vis and FTIR-ATR spectroscopy as well as DMTA analysis. The results revealed that Ceria nano particles with concentration of 1.44 % (wt) absorb beyond 92.5% of UV light of UV-B region and showed an efficiency of 2000 times as of organic UV absorbers.
