[Invisible coating designed to “Eat Smog” off any building | ZnO Shield™ Super-Hydrophilic Photocatalytic Oxidation (UV-PCO) Self Cleaning Technology ZnO Shield™ will perpetually reduce contaminates on contact and when activated with light it becomes photocatlytic generating highly reactive oxygen species like OH−, H2O2, and O2−. The negatively charged hydroxyl radicals and superoxides are extremely powerful "scrubbing bubbles" that virtually eliminate all volatile organic compounds and malodors. This phenomenon is know as ultraviolet photocatalyst oxidation…]
