SymbiCoat™- Smart Functional Coatings Technology




SymbiCoat™ is unmatched in its ability to rapidly and repeatedly uptake sodium hypochlorite and stabilize it on surfaces.

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.



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. 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  provides an extended period of efficacy as compared with use in conjunction with polymers not containing the novel monomer

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.

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.


*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.
