The present investigation proposes the design and manufacture of organic-inorganic hybrid silicone-epoxy anti-soiling coatings for the retrofit of "already-in-use" glass panels. Synthesis of the anti-soiling formulation, setting-up of the deposition and drying process and analysis of the operational parameters were investigated. The resulting coatings were characterized in terms of micro-mechanical and tribological response and resistance to chemicals. In addition, the anti-soiling and anti-graffiti performance against inorganic dusts, carbonaceous pollutants and permanent markers was tested according to standardized procedure. The silicone-epoxy coatings were found to protect the glass substrates from soiling with contaminants, showing a high potential to preserve the initial efficiency of the related solar-energy systems over long time. © 2014 Elsevier Ltd.

Abstract
The present investigation proposes the design and manufacture of organic-inorganic hybrid silicone-epoxy anti-soiling coatings for the retrofit of "already-in-use" glass panels. Synthesis of the anti-soiling formulation, setting-up of the deposition and drying process and analysis of the operational parameters were investigated. The resulting coatings were characterized in terms of micro-mechanical and tribological response and resistance to chemicals. In addition, the anti-soiling and anti-graffiti performance against inorganic dusts, carbonaceous pollutants and permanent markers was tested according to standardized procedure. The silicone-epoxy coatings were found to protect the glass substrates from soiling with contaminants, showing a high potential to preserve the initial efficiency of the related solar-energy systems over long time. © 2014 Elsevier Ltd.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
