Coatings are one of the oldest methods of surface treatment that, when applied to the substrate, have protective and decorative properties. Coatings are also called composites due to their complex chemical composition, which consists of a binder as the main ingredient that combines other components (pigments, fillers, additives). Facade coatings are particularly exposed to the inevitable effects of weathering, which means that the coating must be constantly renewed for decorative and safety reasons. With the development of civilization, man strives to simplify various aspects of life, and as a result, some researches focus on the development of coatings with self-cleaning effect. At the same time, the awareness of ecological safety brought the idea of reducing volatile organic components, which have a large proportion in conventional coating formulations. The solution to the above problem is seen in silicate coatings. The aim of this work was to investigate the effects of different amounts of colloidal nano-silica (nano-SiO2) and potassium water glass as an inorganic binder on the properties of silicate coating and to test the possibility of achieving the self-cleaning effect. For this work, four dispersions were prepared, one of which didn't contain nano-SiO2 and the other three contained different amounts of nano-SiO2 and potassium water glass. The dispersions contained the same amount as the other components. The effects of different amounts of nano-SiO2 and potassium water glass on the properties of dispersions and dry films were investigated. Immediately after the preparation of the dispersions, the basic property was determined. The rheological properties of the dispersions were also investigated. The properties of the dry films were studied by analyzing the adhesion of the film to the substrate, water absorption, water vapor permeability, and contact angle. The thermal properties of the coatings were studied by differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). The stability of the samples under atmospheric conditions was investigated by exposing them to six months of natural aging in the weathering station and conditions in the QUV accelerated weathering tester. The self-cleaning effect was studied by the internal method using carbon dust.
