Antimicrobial Window Films

ZIR Antimicrobial Window Films

Using our antimicrobial face-shield technology, FILMTACK has developed ultrathin nano-islands coating on window film surface to offer protection against SARS-CoV-2 virus (lab-tested).

Tests conducted by independent laboratories have proven that this specially-coated surface can offer lasting protection from bacteria, including common bacteria such as Staphylococcus aureus, E. Coli, etc. The advanced coating also contains antiviral technology which reduces the survivability of SARS-CoV-2 virus on glass surfaces in 24 hours. It is suitable for use in hygiene conscious environments where clean-ability, scratch resistance, and the transfer of microbes is a concern.

Product Features

Technical Information

ZIR is a window film with an ultra thin antimicrobial coating on the surface. While the product feels smooth to the human skin, the surface is a nano-islands structure when superimposed. These nano-islands are a durable and stable coating that creates a hostile environment to the microbes and viruses.

ZIR is a high heat-reduction window film, lab-tested to provide an average of 32% reduction (up to 62%) of SARS-CoV-2 on glass surfaces after 24hours. In many countries, the SARS-CoV-2 virus is categized at biohazard level 3 and above, available for public commercial testing until recently. Many non-medical, commercial claims of efficacy against coronavirus, are either tested with pre-2019 strains, animal coronavirus, or the surrogate Murine Hepatitis virus to demonstrate the antiviral efficacy of this technology against a member of the coronavirus family.
