Photocatalytic oxidation (PCO) is a process that utilizes the energy from light to activate powerful redox reactions on the surface of a semi conductor photocatalyst. PCO takes place when UV llight(ambient, sunlight or light from electric lamps) activates a semiconductor photocatalyst in the presence of oxygen and moisture. Activation of the catalyst generates hydroxyl radicals and superoxide ions, powerful oxidizing species which attack, break down and kill a variety of organic compounds. Unlike absorbents, Photocatalytic Oxidation is a process that chemically destroys compounds by oxidation reactions. The process does not utilize toxic chemical agents, so there is no danger of leaching materials from the photoactive coating. The by-product of this oxidation process of organic molecules is CO2, H2O and dilute mineral acids.
This (PCO) process is both invisible and constant. As long as there is light, the Radiant Shield™ Coating continues to destroy harmful biological and chemical contaminates. Unlike traditional chemical based cleaning products that do not protect surfaces from recontamination. Radiant Shield™ Coating provided lasting protection, by persistently providing a healthier, safer and cleaner environment.
