ABSTRACT Linear long chain hydrogenated acrylic monomers, alkoxysilane monomers and fluorinated acrylates were tested as modifying additives for acrylic UV-curable systems. They caused a dramatic change of the surface properties of the films, without changing their curing conditions and their bulk properties. XPS and RBS measurements showed that the additives are able to concentrate selectively on the surface of the films. The relationship between the chemical structure and concentration of the additives and the final surface properties of the films are investigated.
