In this study, it is aimed to obtain UV-cured nanocomposite coatings. UV-curable epoxy acrylate resins were synthesized by reacting aliphatic-based epoxy resin with adipic acid and acrylic acid at certain rates and their chemical structures were characterized. The synthesized resins were reinforced with organonanoclay at different rates, applied as a film to plexiglass surfaces and cured with UV rays. The thermal properties, flammability, thermomechanical properties, surface properties, morphological properties, light transmittance and durability properties of the obtained nanocomposite coatings containing organonanoclay were investigated. With 5% organonanoclyay reinforcement to the epoxy acrylate resin, the temperature of final mass loss increased from 521 to 557 degrees C, char yield increased from 0.02% to 2.95, LOI increased from 22.1 to 23.5%, contact angle increased from 56 to 74 degrees. The results showed that UV-cured nanocomposite coatings have the properties required by the coating industry, and these properties are improved with the addition of organonanoclay.
