AN AGENT FOR SURFACE FINISHING OF OBJECTS AND STRUSTURES BY A COATING LAYER WITH A PHOTOCATALYTIC AND SELF-CLEANING EFFECT AND RESPECTIVE MANUFACTURING PROCESS

摘要

An agent for surface finishing of objects and structures by a coating layer with a photocatalytic and self-cleaning effect, above all with the catalytic effects of air pollutants´ photodegradation. It is created by a precursor based on a dispersion of at least one compound from the group of metals´ oxids and salts in nanocristalline form, which is photoactive even in the visible band of the solar radiation spektrum. The precursor said being a hydrolysis product of respective metal´s soluble salt in the medium of silicates, silicic esters, siloxanes or silicon alcoxides.
