1 Photocatalytic Paint Coatings Acrylate/Silicate/Silicone Free Superior Performance Industrial and exhaust exhalations, organic contaminants from plastics and many other substances around us are threat to human health and they lower the quality of our environment. According to the WTO, more than 15% of chronic diseases are caused by bad air quality. A high percentage of allergies, contagious infections, bad odors or darkening of facades are a few examples of the impacts of contaminated air. Man is forced to protect himself and one exciting possibility is the use of photocatalytic coatings. i

2 MECHANISM CONVERSION OF LIGHT ENERGY INTO AN OXIDATION POTENTIAL ON THE SURFACE OF TITANIUM DIOXIDE HOW DOES IT WORK? ORGANICS + (SMOKE, MICROBES, VAPOUR, ETC) AIR OXYGEN + LIGHT H 2 O + CO 2 + TiO 2 SURFACE Eg ~ 3.2eV

3 Smoke and oxygen co-exists in the air without any problem. Smoke creates musty deposits on a regular wall. Regular paint 6 months FN-2 When smoke comes into contact with the photocatalytic surface, it reacts with the oxygen (burns) creating molecules of water, CO 2 and other mineral compounds.

4 FIRST GENERATION OF TiO 2 PHOTOCATALYTIC PRODUCTS PAINTS Silicate, silicone or organic binders Block the TiO 2 surface Bond to the active sites Photocatalytic paints 100% TiO 2 VERY LOW EFFICIENCY

5 SILICATE COMPOSITIONS LOW EFFICIENCY CHEMISTRY INVOLVED High hiding power Suitable for some applications Aggregates in SiO 2 pudding

6 NEW GENERATION OF PHOTOCATALYTIC COATINGS!!!!!Accessible TiO 2 surface!!!!! High TiO 2 loading QUALIFIES AS AN AIR CLEANING SYSTEM

7 NO SILICATES NO ORGANICS NO SILICONES NO SOL-GEL 100% TiO 2 VERY HIGH EFFICIENCY

8 MAIN DIFFERENCE: EXCELLENT ACCESSIBILITY OF THE TiO 2 SURFACE The inorganic binder does not make a bond to the TiO 2 surface such as silicates or silicones

9 BINDER TiO 2 TiO 2 nanoparticles are not covered by the binder=acessible SURFACE

10 PHOTOCATALYTIC SUSPENSIONS Certified for concrete treatment and protection PROTECTED BY A PATENT AND REGISTERED TRADEMARK MEET CZECH AND EUROPEAN NORMS AND REGULATIONS: EN :2004 ČSN EN :2006 ČSN EN :2009 ČSN EN :2005 ČSN EN :2009 ČSN EN :2005/Opr.1:2007 ČSN EN ČSN EN 1542:2000 Zákon č.22/1997 Sb.

11 PHOTOCATALYTIC THIN COATINGS: - PROTECTIVE COATING - AIR CLEANING SYSTEM!!!COMPLETELY INERT NO CHEMISTRY INVOLVED!!! NOT A PAINT! Water suspensions of photocatalytic titanium dioxide and special inorganic binders are used to make a thin active coat on an existing painted surface. Easy installation 5-10 micron thin film is activated by day light or another UV source.

22 PERFECTLY SAFE The active compound in FN1 and FN2 is photoactive titanium dioxide (TiO 2 ), which is a common pigment We can find it just about everywhere (paper, paints, plastics, whipped cream, bread). TiO 2 does not represent any health risk. The photocatalytic layer is ph neutral and non-irritating Ecologically friendly Maintenance recommended - once a year 1 hour irradiation with a strong UV source.

23 ADDITIONAL BENEFITS ANTI-GRAFFITI Difficult penetration of the hydrophobic solvents in sprays into the FN layer => large consumption of spray paint Relatively easy removal with a hard brush
