Unlike other antimicrobial coatings, SiO2 International antimicrobial variants have been developed without the use of  “leaching or active agents”.

Most antimicrobial coatings work by using “active or leaching agents” which pass through the coating to poison bacteria. Although somewhat effective, there is a danger of bacteria becoming resistant to these chemicals developing into “super bugs”. At SiO2 International we chose a different approach to control problem microbes. Realizing the importance of a safe and effective alternative, we successfully married our SiO2 Technology with a “3-(trimethoxysilyl) propyldimethyloctadecyl ammonium chloride” or si-quat molecule. First developed by Dow Corning and considered by the FDA as one of the safest and most effective innovations to manage bacteria, si-quat technology controls bacteria through a mechanical process that bacteria cannot become resistant to.

SiO2 International uses no silver nanoparticles, triclosan, sodium pyrithion, benzalkonium chloride, or other agents in our coatings.

Toxic chemicals like these agents have a history of becoming problematic.  Once regarded as the “savior” of the healthcare industry, triclosan is considered by The European Union “as an irritant” and states “that it is dangerous for the environment and very toxic to aquatic organisms.” We are witnessing European companies removing products that contain this toxic chemical and their governments considering an all out ban. “One concern with triclosan and similar antimicrobials is that bacteria will develop resistance pathways that not only reduce the efficacy of triclosan, but also to antibiotic therapy.”  states the Canadian Medical Association. In the U.S., there is a private members bill trying to control the use of triclosan domestically. It is found in thousands of industrial and consumer products in the U.S., and in the next few years we believe triclosan will be banned in North America. In the past, German coatings used triclosan but now use other “accepted” leaching agents mentioned above. With the development of our unique antimicrobial coatings, we avoid many of the problems these chemicals have now and may have in the future.
