Novel UV-photopolymerizable siloxane-modified methacrylate/ Boehmite nanocomposites were experimented as possible protective coatings for different substrates. To this aim, unfilled and Boehmite-filled suspensions were applied and photocured on a glass substrate. A subsequent detailed experimental characterization was performed in order to evaluate the effect of the presence of Boehmite nanoparticles on the surface properties of the coatings and on their durability characteristics. In particular, transparency, glass transition temperature, scratch, and surface hardness, contact angle, and color change were measured on the coatings applied on glass support before and after QUV accelerated weathering cycles.
