The Nanocomposite group of AIDICO and the Nanomaterials Group of University of Valencia collaborate in the development of new nanocomposite materials of epoxy matrix with application in construction materials. Tribological properties and good thermal stability are some of the achieved specifications for these applications. Some hybrid coatings based on the "in situ" formation of nanosilica are presenting in this work. Elastic modulus and hardness obtained from TDMA analyses and nanoindentation techniques, together with thermal stability by TGA, are the main properties analysed in this work in order to fit the requirements of stone coating applications. New routes for obtaining these coatings based on sol-gel have been explored. Structural characterization by SEM is also correlated with the final properties.
