JW Winco added antibacterial protection to a series of standard parts, grouped into the sanline product family. The handling elements: buttons, hand levers, U-handles and wing nuts, make use of two different principles. In the case of plastics, special additives with silver ions are mixed in, while metal parts are given powder coatings based on zinc molybdate.
Both principles destroy the cell walls of the microorganisms, causing them to die. Zinc molybdate additives are of particular interest. With the help of moisture in the air, an acidic film with a pH of about 4.5 forms on the surfaces, similar to the one on human skin. The acid protons penetrate the cell membrane of the bacteria and destroys them.
