Horizon 2020 Phase II

A breakthrough in rechargeable N-Halamine technology for unparalleled antimicrobial efficacy on hard surfaces

Exigence Technologies is a proud recipient of a H2020 SME Instrument Phase 2 grant through Exigence Technologies UK Ltd.

The project will be executed through Exigence Technologies UK ltd and Exigence technologies France SAS.

Exigence SymbiCoat™ represents a fundamentally different approach for creating materials which can prevent pathogens from surviving on a surface, and can also inhibit the presence of dangerous biofilms. The technology is revolutionary when compared to the products that dominate today’s antimicrobial coatings market. Most antimicrobial coatings rely upon a relatively simple but flawed premise. A toxic active ingredient, such as silver, copper or zinc in various forms, is impregnated into the coating. That active ingredient leaches out to contact and kill germs. This means the store of the chemical that provides the antimicrobial action is relatively quickly depleted and over time, the ‘antimicrobial’ effect is diminished.. In addition, this leaching of toxic chemistry has negative implications for the aquatic environment, food safety and human and animal health.

SymbiCoat™ chemistries modify existing coating materials (vinyls, epoxies, polyurethanes and others) through a method that does not contain a disinfecting chemical or active ingredient. Instead, SymbiCoat™ technology provides surfaces with the regenerable capability to   rapidly bind or scavenge the ECHA (European Chemical Agency)-registered sodium hypochlorite onto the coating. Sodium hypochlorite is one of the most widely used, cost-effective and well understood disinfectant chemicals available globally. Exigence SymbiCoat™ allows the sodium hypochlorite to provide a much longer period of action than would otherwise be possible with the liquid alone, even at levels that are safe for food contact. Thus, SymbiCoat™ has the potential to significantly enhance longevity of contamination control in the food industry, where food safety and prevention of foodborne diseases is a top priority.
