Contact infections with viruses, fungi, and bacteria were already a problem even before the pandemic. Now, JW Winco — the standard parts specialist — is expanding its Sanline range of antibacterial products.
Bacteria with high resistance to common antibiotic therapies have been on the rise for years. Resulting infections can become a serious problem even outside of healthcare facilities. One part of the solution involves surfaces that people come into contact with, including 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 is, typically, transferred to the next user.
However, the fewer micro-organisms present on such surfaces, the lower the infection risk. Frequent cleaning and disinfection is one solution, but it’s prone to errors and can exhibit problematic gaps. It’s far more effective for the surfaces to simply have an antimicrobial effect. Any micro-organisms coming into contact with such surfaces are, then, deactivated and this prevents their transmission. Moreover, such effects can be very long-lasting.
JW Winco 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 devices — including 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 micro-organisms, causing them to die. For humans, contact with activated surfaces poses no risk whatsoever.
Zinc molybdate additives are also of 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 with frequent cleanings. (Note: The antibacterial properties are no replacement for cleaning or disinfection, but they serve as a long-lasting additional measure.)
