Frequently Asked Questions
How does the organo-silane technology work?
The active ingredient in the QS72-5 CS product forms a colorless, odorless, 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 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.
What is the purpose of the silane portion of the molecule?
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.
Is the QS72-5 CS product quaternary compounds?
Yes and no. The active ingredient is an organo functional 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.
What is the difference between organo-silane products and other antimicrobials on the market?
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. Our 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 antimicrobial active.
Against what types of bacteria is the technology effective?
The technology has a mode of action that involves a positive charge and is effective against all bacteria, plus fungus, algae, and mold.
Will this technology adversely affect the skin or environment?
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.
What biocide is used?
The active ingredient is 3-(trimethoxysilyl) propy octadecyl dimethyl ammonium chloride.
Does the biocide use a heavy metal?
For Soft Furnishing: The product is applied in aqueous solution and can be applied by wiping, airless sprayer, It can be applied to interior and exterior surfaces excluding a food grade surface. The antimicrobial is cationic so it mixes well with other cationic and nonionic finishes.
For Hard surfaces: can be treated on any hard surfaces by either fogging, wipe down, soaking or paint rollingon the target substrate.
How long does the treatment last?
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, especially 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.
Is there a test method to determine if the polymer is present?
Yes there 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 its presence.
What tests show that the growth of bacteria has been prevented?
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. We have over 50 years’ experience in performing extensive microbiological tests such as bacterial retrievals, fungal growth test…..do you?
Why are the antimicrobial products so durable?
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.
Is the Antimicrobial permeable to moisture?
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.
Will its use result in 'super bacteria'?
No. Adaptation studies show that microbes do not adapt to the technology and no ‘Zone of Inhibition’ develops.
Does the Antimicrobial give off gases during or after application?
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.
Is there regrowth after treatment?
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.
What should the moisture content of walls be when preparing to apply treatment?
As long as there is not 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.
Will the Antimicrobial affect the cooling capacity of AC coils?
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.
What preparation is necessary for treating coils?
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.
What is the difference between Cover Shield® antimicrobial and other antimicrobials (ex. Milgo, Microban, etc.)?
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 penetrate living cells and kill by way of poisoning the organism. They are designed to act quickly and dissipate quickly to avoid adverse effects to humans and animals due to their toxic ingredients. Cover Shield® Antimicrobial takes a totally different approach. Like conventional antimicrobials it provides an effective initial microbial kill when it is applied, BUT, unlike the others, Cover Shield® also provides long-term control of growth on treated surfaces. The Antimicrobial permanently modifies a surface to make them antimicrobial.
How does the chemical work?
The active ingredient in the 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 buildup, paint, dead microbes, etc. will cover the treatment prohibiting it from killing microorganisms.
Do the applicators receive any special kind of training?
Yes. We pride ourselves on providing a superior product to all those in need of controlling and prohibiting microbial growth on interior surfaces. To ensure proper use of the Antimicrobial, each applicator receives training and on-site training if needed. What training materials do you provide or recommend?
What does the application process entail?
In the simplest terms, (1 part to 3 parts water) is the mixing ratio and is sprayed on the surface in an even and uniform pattern. How fast the solution is applied is based on how porous the surfaces are. The more porous a surface, the slower application. Apply from the top down; (wet not dripping) starting with the ceiling and finishing with the floor. 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.
Are there any safety concerns after application is complete?
IThis product will not give off any gases, leach onto other surfaces, or lose its strength over time. The unique properties of the 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. Always wear PPE gear for tech protection.
What preparation is necessary prior to applying the treatment?
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. Clo2 Deliver Systems’ LiquaSan is a multi-purpose cleaner that is designed for this type of application.
How does the Antimicrobial react with Oriental Rugs?
True Oriental and Native American rugs frequently use water based dyes and these dyes will bleed when exposed to the water based application strength solution of the Antimicrobial. Companies specializing in cleaning these types of fabrics have special methods for applying water based treatments.
How does the Antimicrobial react to carpet cleaning agents?
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
How does the antimicrobial react to commercial and residential carpets?
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.
How should a contaminated surface be treated?
Microbes can be extremely hazardous. Severe contamination with hazardous organisms may require cleaning protocols similar to those for asbestos removal. 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.
Should heating coils be treated with the Antimicrobial?
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.
