Influence of Different Kinds of Paints on Self-Cleaning Process of the Facade Coating

Abstract

This work summarizes assessing the durability results of facade coatings in the area of their resistance of the self-cleaning effect. To characterize this feature three different types of samples were chosen: Silicone paint, photocatalysis effect paint and lotus flower effect paint. Test samples were exposed on natural conditions and artificial weathering process in laboratory at the same time. After this research, durability effect of self-cleaning properties and stain resistance by established criteria were obtained. LM and SEM micrographs, contact angle and profilometry were used widely to measure this factor. In conclusion, all of tested facade coatings based on silicon exhibit the highest effect of self-cleaning.
