The PURPLE GUARD Antimicrobial Coating uses cutting edge technology that consists of Quaternary Ammonium Compounds. It disinfects and shields surfaces from disease-causing microbes including viruses, bacteria, mould and fungi. Once the coating is applied on any surface, a nanoscale layer is formed with microscopic needles – they mechanically puncture and kill any virus or bacteria strands that fall on the PURPLE GUARD coated surface. This process interrupts the essential function of the cell membrane and the protein activity, ultimately eliminating the disease-causing microbe. During and after this process, the coating remains intact and retains its antimicrobial abilities providing long term antimicrobial functionality. PURPLE GUARD has been extensively tested.
