Dry Mix for Facade Self-Cleaning Silicate Paint

Abstract

This paper presents the results of a study on one-component dry mix used for the preparation of silicate-based facade paint with self-cleaning properties. The advantages of the developed composition include the ease of the mix preparation and application, increased adhesion of the coating to the base, and improved aesthetic qualities of the coating provided by its ability to self-clean due to the addition of nanotitanium dioxide, which enhances photocatalysis. In the course of the research work, the optimal quantitative content of the main components and functional additives was established. Studies of the facade paint microstructure were carried out. Infrared spectral and differential thermal analysis of the composition confirmed the significant weather resistance of the facade paint, which is ensured by deep carbonization of the constituent components with their transformation into calcium carbonates, characterized by increased water resistance and chemical stability. Key words: facade coating, silicate paint, self-cleaning, photocatalysis, microstructure
