The patented products are solvent-free water-repellent hybrid nanostructured materials successfully experimented as protective coatings for different substrates (stone, concrete, wood, glass, etc.). They are able to speedily set and harden in presence of UV-solar radiations, additionally displaying superior properties in terms of hardness, superficial resistance and durability. The license of such products was sold and commercialized by an Italian Company (Dell’Anna Muia, Copertino, Lecce). The hybrid products, in fact, are particular suitable for the protection of the surface of a tender stone (Lecce stone) employed in ancient/old constructions located in Salento area (Apulia Region, Italy): the hybrid coating displays outstanding protective properties in terms protection of the stone from water action and weathering. The possibility for this product to harden when exposed to sun radiations eliminates the necessity to use external sources of energy (lamps, heaters, etc.), making more feasible the use of the patented product also in construction applications, where large surfaces, not always easily accessible, must be treated.

The third patent is on a hybrid nanostructured product proposed as adhesive for industry and construction/Cultural Heritage applications. This hybrid adhesive is proposed for different organic and inorganic substrates, such as: polymers and composites, concrete, stone, wood, glass, etc. The nanostructured hybrid adhesive can be “cold-cured”, i.e. it is able to set and harden at ambient temperature in reduced times with respect the commercial available products, presenting in addition superior durability performance. The product is eco-friendly not containing any solvent.
