Frequently Asked Questions

Yes, the EPA registration number is EPA Reg. No. 64881-2

The active ingredients in DeOdorPRO Covershield® Antimicrobial forms a colourless, odourless, positively charged polymer that molecularly bonds to the treated surface. You could think of it as a layer of electrically charged swords. When a microorganism comes in contact with the treated surface, the C-18 molecular sword punctures the cell membrane and the electrical charge shocks the cell. Since nothing is transferred to the now dead cell, the antimicrobial doesn’t lose strength and the sword is ready for the next cell to contact it.

Silanes are extremely efficient bonding agents that can be coupled to other molecules and then used to permanently bond those molecules to a target surface. Our antimicrobial silane modifies virtually any surface and transforms it into a material that will not support microbial growth.
Yes and no. The active ingredient is an organofunctional silane, but part of the molecule is a quaternary compound. Unlike traditional quats, which have a limited kill spectrum, the technology provides long-term protection and controls a wide range of microorganisms including bacteria, fungus, algae, and mold.
Conventional products penetrate living cells and kill by way of poisoning the organism or disrupting a vital life process. They are designed to act quickly and dissipate quickly. Most commercial antimicrobials used for treating surfaces do an adequate job of killing bacteria and fungi, although most have a limited range of effectiveness. The technology takes a totally unique approach. It provides an effective initial microbial kill when applied, but, unlike the conventional methods, it also provides long-term control of growth on treated surfaces, often for the life of that surface. The surface itself is modified to make it antimicrobially active.

The DeOdorPRO Covershield® Antimicrobial technology has a mode of action that involves a positive charge and is effective against all bacteria, plus fungus, algae, and mold. A representative list of microbes against which the DeOdorPRO Covershield® Antimicrobial technology has been tested may be obtained by contacting our corporate office.

No. Since the antimicrobial is permanently bound to the surfaces it protects, it does not leach from the fabric to the skin or into the environment. Extensive toxicological testing shows the antimicrobial does not cross the skin barrier. In fact, is so safe, that it is used on baby nappies to prevent nappy rash.
The active ingredient is 3-(trimethoxysilyl) propyl octadecyl dimethyl ammonium chloride.

No, DeOdorPRO Covershield® Antimicrobial products do NOT contain any heavy metals. Tin, arsenic, silver and copper are often used in other antimicrobials.

For Soft Furnishing: DeOdorPRO Covershield® Antimicrobial products are applied in aqueous solution and can be inserted into almost any wet process during manufacturing at the mill. They can also be applied to finished goods. The antimicrobial is easily integrated into most jet, pad, and batch processes. The antimicrobial is cationic so it mixes well with other cationic and nonionic finishes (most softeners) and performs well in the same bath.

For Hard surfaces: can be treated on any hard surfaces by either fogging, wipe down, soaking or paint rolling or with the use of an airless paint sprayer on the target substrate.

Since the cured antimicrobial is nonvolatile, insoluble, and non-leaching, the treatment should last for the life of the treated surface. The life of a treated surface depends on a number of factors, not the least of which is surface preparation. If you treat a dirty or unstable surface, when the dirt comes off or the surface is disturbed, some of the antimicrobial will be removed with it. Abrasive or caustic (pH>10.5) cleaners will also shorten effective life.

Yes, DeOdorPRO Covershield® Antimicrobial is based on an active ingredient that, in most cases, can be easily detected. A simple method of detection is available to demonstrate the presence or absence of the treatment. Bromophenol Blue (BPB) stain testing clearly shows the presence of the Microbe Shield in a matter of minutes.

Microbiological testing is what establishes the baseline standard that is used to give the BPB analytical procedure its validity for use as a QA and QC tool. Our team has over 50 years’ experience in performing extensive microbiological tests such as bacterial retrievals, fungal growth tests (AATCC 30, ASTM G-21) and bacterial growth tests (AATCC 100, ASTM 2149-01). We have a long history of bacterial and fungal testing on many products including shoe linings, leather, socks, carpet and building products. Specific studies are available on our web site or you may contact a sales representative.

Because of their exceptional chemical bond (a covalent bond), the bonded polymer is neither soluble nor volatile. The unique bond results in the antimicrobial polymer becoming an integral part of the substrate.

No. Adaptation studies show that microbes do not adapt to DeOdorPRO Covershield® Antimicrobial and no ‘Zone of Inhibition’ develops.

No. The Antimicrobial does not volatilize, dissipate, or leach onto other surfaces. Its chemistry polymerizes where it is applied and forms a permanent bond that essentially lasts the life of the treated surface. Normal cleaning should not remove the treatment, although it can be abraded away.

Yes, moisture that is in or on the treated material/surface passes through the treatment. After curing, the treatment is somewhat hydrophobic (water repellent), but it should not be considered to be a replacement for commercial water repellents.

The Antimicrobial, because of its unique chemistry, provides long-term protection against regrowth and future contamination on treated surfaces. Porous surfaces which are contaminated below the surface will occasionally experience some growth which breaks through a treated surface.

Semi wet or damp surfaces can be treated. As long as there is no running water on the surface to be treated, the Antimicrobial will bond to the surface and provide protection. Preferably, the dryer the surface the better. To complete chemical bonding of the Antimicrobial, it is important that the surfaces be dried after treatment.

Yes. The Antimicrobial should actually improve the overall cooling performance of AC coils by minimizing organic fouling of surfaces. The Antimicrobial helps minimize the microbial attack and attachment to fin and tube surfaces. An added benefit of the Antimicrobial is its ability to act as a permanently bonded soil release agent, making the coils much easier to clean. The Antimicrobial, at application strength, has surfactant properties which cause excess treatment to run off. This prevents excess polymer buildup and potential heat transfer efficiency losses.

The surface of the coils must be thoroughly cleaned and any residue from the cleaning agents must be rinsed off. The final rinse should come through the coil without any signs of dirt or foaming from the cleaners. Even new AHU’s or coils should be carefully cleaned to remove any machining lubricants which remain from the fabrication process.

Most commercial antimicrobials used for treating building surfaces do a great job getting a quick kill on bacteria and fungi (although some have a limited spectrum of effectiveness). Conventional products kill by way of poisoning the organism. They are designed to act quickly but have harmful side effects. The use of Selectrocide, an EPA registered disinfectant (EPA Reg. No. 74986-5), eliminates all of these health and environmental concerns caused by traditional disinfectants (Contact CLO2 Delivery System for information about Selectrocide). Our Antimicrobial takes a totally different approach. Like conventional antimicrobials it provides an effective initial microbial kill when it is applied, BUT, unlike the others, this Antimicrobial also provides long-term control of growth on treated surfaces. The Antimicrobial permanently modifies a surface to make them antimicrobial.

The active ingredient in DeOdorPRO Covershield® Antimicrobial forms a colorless, odorless, positively charged monomer which molecularly bonds to the treated surface. You could think of it as a layer of electrically charged swords. When a microorganism comes in contact with the treated surface, the quaternary amine “sword” punctures the cell membrane and the electrical charge “shocks” the cell. Since nothing is transferred to the now dead cell, the antimicrobial doesn’t lose strength and the “sword” is ready for the next cell to contact it. In order for the Antimicrobial to continue its effectiveness, normal cleaning of treated surfaces is necessary. Dirt and oil buildup from hands, paint, dead microbes, etc. will cover the treated surface prohibiting it from killing microorganisms.

Yes. CLO2 Delivery Systems prides itself on providing a superior product to all those in need of controlling and prohibiting microbial growth on interior surfaces. Therefore, to ensure proper use of the Antimicrobial, each applicator should receive four hours of classroom training and on-site training. In addition, they receive a training manual and ongoing access to our technical expertise.

For best results, surfaces should be thoroughly cleaned and any residue from cleaning agents must be rinsed from the surfaces to be treated. The final rinse should come off without any signs of dirt or foaming from the cleaners. We recommend the use of our Selectrocide disinfectant (EPA Reg. No. 74986-5). Which is also on the federal government LIST N for killing Coronavirus. It can be used with our cleaning agent. But when used without, it leaves no residue as chlorine dioxide is a soluble gas in water and leaves no residue once the surface dries. For cleaning purposes, we recommend using Selectrocide’s cleaning additive.

In the simplest terms, one-part solution to three parts water is made and sprayed on the surface in an even and uniform pattern. How fast the solution is applied is based on the porosity of the surfaces or substrate. The more porous a surface, the slower application. Apply from the top down; starting with the ceiling, then walls. Hard floors and carpets are optional but can be sprayed. Furniture and other items should be moved to another room if possible. Anything which stays in the room and could be damaged by water should be covered. Use pads under any metal legs or slides to avoid rust stains. Opening of windows and the use fans will be used to speed drying.

This product will not give off any gases, leach onto other surfaces, or lose its strength over time. The unique properties of DeOdorPRO Covershield® Antimicrobial allows permanent bonding of the product to any surface to which it is applied. As long as this the surface is kept clean with normal cleaning procedures, the surface will continue to fight any microbial growth.

Cleaning agents that remain in the carpet will act as bonding sites for the Antimicrobial and the combined molecule will be removed at the next cleaning. A few residual cleaning agents can cause a gummy residue to form.

The newer solution dyed carpets are excellent with the Antimicrobial. There have been some instances of slight color fade with certain acid dyes. ALL carpets and upholstery should be tested for dye fastness prior to treating.

Microbes can be extremely hazardous and disinfection cleaning protocols should be used prior to the application of DeOdorPRO Covershield® Antimicrobial. For normal contamination, solid surfaces should be thoroughly cleaned before treatment. Soft surfaces such as carpets and upholstery should be well vacuumed or professionally cleaned. Insulation can be cleaned and treated if only superficial growth on the surface is present. Insulation that has heavy growth or is damp should be removed and replaced.

No. Although the Antimicrobial would not be harmful when exposed to the heat, treatment is unnecessary. The hot, dry surfaces of coils generally won’t support microbial growth.

Yes, DeOdorPRO Covershield® Antimicrobial Treatment is based on an active ingredient that in most cases can be easily detected. Two methods of detection are available to check for or demonstrate the presence or absence of the treatment.

No, DeOdorPRO Covershield® Antimicrobial is non-regulated and can be shipped anywhere by ground, sea or air.
