One part of the solution involves surfaces that people come into contact with – in other words, handles, buttons, switches, plugs, tables, keyboards and even touch screens. Bacteria, fungi and viruses can collect in these locations, form a biofilm that facilitates growth and eventually be transferred to the next user. Reliably interrupting this very simple transmission route is therefore a worthwhile objective. The fewer microorganisms present on such surfaces, the lower the infection risk.

Frequent cleaning and disinfection is one solution, but it is prone to errors and can exhibit problematic gaps. It is far more effective and reliable for the surfaces themselves to have an antimicrobial effect. Any microorganisms coming into contact with such surfaces are then automatically deactivated, and this prevents their transmission. Moreover, such effects can be very long-lasting.

Ganter began addressing this extremely relevant social problem years ago by adding antibacterial protection to a whole series of standard parts, grouped into the Sanline product family. The various 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. For humans, contact with such activated surfaces poses no risk whatsoever. 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, quickly destroying them.

Both principles remain effective for a long time, even despite frequent cleanings. Note: The antibacterial properties are no replacement for cleaning or disinfection, but they serve as a long-lasting additional measure.
