SymbiCoat™- Smart Functional Coatings Technology

SymbiCoat™ is unmatched in its ability to rapidly and repeatedly uptake sodium hypochlorite and stabilize it on surfaces, to allow the sodium hypochlorite to do what it does best: kill microbes fast. Sodium hypochlorite is a potent, broad-spectrum disinfectant, but in liquid form, its activity dissipates quickly.  SymbiCoat™ monomers allow chlorine to remain on the surface for extended periods of time, so that the stabilized chlorine can continue to provide microbial protection.

Where Clean is Critical – choose SymbiCoat™.


How It Works

Exigence Technologies has developed the highly-effective, ‘stimulus-responsive’ SymbiCoat™   family of monomers for incorporation into a variety of coating resin/binder systems, such as acrylics, epoxies & polyurethanes.

SymbiCoat™ monomers efficiently and repeatedly stabilize chlorine on a surface and therefore allow the chlorine to exert long-lasting and renewable microbial control. SymbiCoat™ monomers are non-leaching molecules that can be permanently bound or polymerized into several widely-used coating resins and coating formulations.  SymbiCoat™ monomers have no inherent microbicidal activity either alone or within the polymer coating.  Upon exposure to dilute (1-200 ppm) solutions of sodium hypochlorite in water, SymbiCoat™ monomers are highly effective at attracting chlorine ions and stabilizing them on a surface. This permits the well-known, agency-registered chlorine to “rest” on the surface where the chlorine can contact and rapidly eliminate bacteria, viruses and fungi. Even drug-resistant microbes can be efficiently eradicated because chlorine is an oxidizing agent that has does not induce microbial resistance.

Agency-registered sodium hypochlorite is one of the most widely used, cost-effective, and well understood disinfectant chemicals available globally. Exigence SymbiCoat™ stabilize sodium hypochlorite such that the sodium hypochlorite can provide a significantly longer period of action than would otherwise be possible, even at levels that are safe for food contact.  It has been shown that, upon exposure to a dilute sodium hypochlorite solution, SymbiCoat™ can extract the chlorine and stabilize it on a surface for up to 400 days.

Stabilization of chlorine at the material interface is a unique approach which may disrupt microbial attachment to the surface, creating ‘bottom up’ microbial control.

Sodium hypochlorite alone is typically poor at penetrating through organic films; however, surface-stabilized chlorine is better at mitigating organic load challenges.  SymbiCoatTM contains proprietary features which make our monomers resistant to protein adsorption.


Better Than Market-Leading Silver Technology

Chlorine stabilized on a surface supports significantly faster kill than market-leading silver technologies. Most antimicrobial coatings, such as those infused with silver and silver ion, depend upon a “leaching” mode of action. A toxic active ingredient, such as silver, copper or zinc is incorporated in the coating and the antimicrobial functionality is provided by the leaching of these toxic antimicrobials out of the substrate.

This means the store of antimicrobial active ingredient is subject to continuous depletion.  As a result, the anti-microbial activity decreases over time.  High loading of surfaces with these toxic anti-microbials can cause issues such as skin discoloration. Cleaning practices, including the use of chlorine can deplete the metal active ingredient very rapidly. Furthermore, some experts contend that leaching of toxic chemistry has negative implications for the aquatic environment, food safety and human and animal health, and silver nanomaterials have been the subject of much debate and controversy in this regard.

Using industry-standard test protocols, our testing shows that EPA-registered sodium hypochlorite, when bound to SymbiCoat™ -treated surfaces, can kill drug-resistant bacteria at least 100 times faster than today’s market-leading silver technologies. SymbiCoat™ monomers are permanently bonded into coatings and polymers, and do not leach out.  Their functionality remains integral to the surface, and the chlorine stores can be recharged within minutes with a simple wash or spray of dilute sodium hypochlorite.


SymbiCoat™ Rechargeability & Longevity

One of the most unique characteristics of SymbiCoat™ monomers is their “rechargeability”. The germ-killing activity of EPA-registered sodium hypochlorite can be rapidly replenished as often as necessary by spraying or rinsing the SymbiCoat™-enhanced material with 1-200 ppm sodium hypochlorite in water. A SymbiCoat™-infused coating will continue to extend chlorine efficacy for as long as the durable formulated coating will last because SymbiCoat™ stabilization and storage capabilities are maintained even when challenged with organic load, submersion in fluid, and repeated cleanings.

Unlike previous generation rechargeable N-halamine chemistries, Exigence SymbiCoat™ not only facilitates faster elimination of microbes by the chlorine, but resists organic fouling, recharges much more rapidly, and uses significantly lower levels of chlorine to recharge. Importantly, sodium hypochlorite is an oxidizer and does not contribute to antimicrobial resistance, unlike the majority of toxin-based antimicrobial active ingredients.

*Note: SymbiCoat™ must be exposed to a halogen such as chlorine (available via sodium hypochlorite) prior to use. Surfaces need to be coated once and then recharged if needed, as long as the coating remains on the surface.  Coating durability is a function of the coating formulation’s physical & mechanical properties and not the properties of the SymbiCoat™ monomer.

If your target segments include Food & Beverage Processing environments, Industrial Water Infrastructure, Industrial Asset Protection or Healthcare Environments & Devices, SymbiCoat™ can add rapid “stimulus-response” functionality and value to your coatings and polymers.

If your customers are seeking better options for high-performance microbial control – think SymbiCoat™.  Where Clean is Critical.
