Abstract: Described is a method for producing a coating with an aqueous coating composition AC, the method comprising the following steps: a) applying the aqueous coating composition AC to a cementitious substrate; b) curing the applied aqueous coating composition AC; wherein the aqueous coating composition AC comprises at least one amino-functional vinyl copolymer VC and at least one epoxy silane ES and the coating composition has a pH of 3 - 6.5 and the weight ratio between amino-functional vinyl copolymer VC and epoxy silane ES (VC/ES) is from 1.0 - 9.5. Since the composition displays self-etching properties on concrete surfaces, cementitious substrates do not have to be mechanically or chemically pretreated before the composition is applied.

Abstract: The preparation of cementitious articles with a high surface finish, useful for the preparation of electrical devices, in particular photovoltaic devices, is described. The process involves exposing a prefabricated cementitious article to specific temperature and pressure intervals, for a given time period, and then coating the article thus treated with a polymer film, preferably based on polyimide, in specific quantities. Heat-resistant cementitious surfaces with a low, controlled and regular roughness, without point- like defects, suitable for the deposition of additional thin films, in particular metallic films and absorbent films, typically used for the manufacture of photovoltaic cells and/ or modules, are obtained.
