<p>Article in the form of a slab or flag fabricated from stone agglomerate coated with thin, transparent films of TiO2 or ZnO, using dry deposition techniques, with a high level of resistance to solar degradation, said article having the form of a slab or flag fabricated from stone agglomerate coated with a thin, transparent film of TiO2 and/or ZnO with low or zero photocatalytic activity, said film being deposited by means of dry deposition, physical vapour deposition (PVD) or plasma enhanced chemical vapour deposition (PECVD) techniques. Said article has a high level of resistance to solar degradation, which means that the resulting material is suitable for external environments.</p> |
