Mechanical properties of modified epoxy-acrylate UV-curable coatings by POSS and Nanoclay

UV radiation curing is a technique widely used to prepare transparent coatings with good properties. The widespread interest for UV systems can be explained by several reasons such as their rapid cure, which can be controlled by light intensity, and their very low energy consumption. UV curable films are being used in microelectronics devices as laminating and encapsulating polymers. There are several other reasons such as solvent free characteristics, application versatility and low temperature operation that industry is interested in these systems. Incorporation of nanoparticles into a UV curable system is expected to improve mechanical properties such as modulus, thermal and dimensional stability and barrier properties. This paper has reviewed the results of studies on this field.
