The improvement of the coated wood durability can be achieved through the use of nanoscale UV absorbers in the coating systems. A multiply usage of the nanoparticles or their mixtures improves the photostability and extends the decorative service life of the finished wood products. Thus, a plenty of the researches, which analyses the nanocomposite wood coating by the means of decorative properties, UV-vis transmission or IR spectra data can be found. Despite that, the lack of information about the coating film mechanical properties has been highly noticed. In this research, the focus is given on the elasticity and ductility of nanocomposite coating film by means of Young’s modulus and elongation at break parameters, which are commonly used to characterize the mechanical properties of the materials. Elasticity of nanocomposite coating film is important in order to predict and to ensure its further performance onto wood surface, where the high impact of surface stress is expected and to guarantee the optimal coating interlock to wood surface as well.
