Self-cleaning products on external thermal insulation composite systems
The use of multifunctional products with self-cleaning properties can reduce surface anomalies and thus enhance the durability of ETICS. The new study aims at evaluating the effectiveness of three protective coatings with self-cleaning additives (i.e., TiO2 nanoparticles), when applied on the surface of ETICS. Three different stains (rhodamine, methylene blue and silver paint aerosol) were applied on the ETICS finishing coat, evaluating the removal of these stains after exposure to natural (solar radiation) light source.
Enhanced the self-cleaning properties
Results showed that the application of the three products lead to a modification of the surface properties (compactness, hardness, gloss, roughness) of the ETICS specimens, and sensibly enhance the self-cleaning, hydrophobic and aesthetical properties of the ETICS.
