PHOTOCATALYSIS - TECHNOLOGY THAT BRINGS NEW OPPORTUNITIES
How does it work?
The principle of photocatalysis is based on chemical reactions caused by the UVA component of sunlight on surfaces treated with our innovative coatings. As a result all settled organic substances and microorganisms decompose into carbon dioxide and water. In other words, just expose the surfaces treated with our smart coatings to sunlight and everything else is done automatically and for free. Thanks to the photocatalytic self-cleaning feature, the surface is continuously freed of contaminated sediments and remains clean.
What to use the technology for?
The utilisation is very wide. For example, we have developed a coating that specifically prevents the growth of algae and fungi. The sanitising effect can be used to protect historical monuments, renovate residential buildings and improve the overall environmental performance of urban areas. Compared to standard products, our coatings excel in long-term functionality guaranteed for 10 years and, in addition, present almost no environmental burden.
Another feature of our coatings is their specifically enhanced antibacterial and antiviral function. The treated surfaces thus help maintain a hygienic and healthy environment. Thanks to such function, our coatings are in great demand in healthcare and food industry. There is also a great potential of our technologies in the Third World countries and in other areas with problematic hygiene. In this respect, the application of our coatings can be very beneficial and of social credit.
Our materials offer completely new possibilities in fighting against summer overheating of urban agglomerations. Cities worldwide participate with 60-80% in the total energy consumption. In winter, large part is constituted by heating and in summer by air conditioning. We are currently developing revolutionary transparent coatings which, thanks to the high reflectivity of visible and infrared sunlight, significantly reduce the temperature of the coated surface. Large-scale application of these coatings on the roofs and walls of commercial buildings and residential houses will lead not only to a decrease of temperature in interiors, but also to a reduction of temperature and refreshing the air outside. In addition, large painted areas will significantly reduce the concentration of volatile organic pollutants due to their photocatalytic decomposition into water and carbon dioxide. Nitrogen oxides gases produced by car engines will also be photocatalytically transformed into non-volatile nitrogen compounds. The combined effect of new coatings will lead not only to a decrease of façade temperature and to corresponding reduction of air conditioning costs, but also to an overall improvement of the air in densely populated urban areas.
We are continuously developing other coating materials with new useful properties. Currently, we are working on seven research projects.
