Antimicrobial Technology

Bacteria Shield™COATING Technology


Sterile Environments line of  anti-microbial coatings (Bacteria Shield™) are powered by state-of-the-art technology and science that fights microbial growth by creating an cationic force field on surfaces  so strong it tears apart the thin cell wall of microbes like bacteria, mold, fungi and algae. The Bacteria Shield™ powered by mPerial™ or mPale™ provides a “physical” destruction of a microbial cell, thus eliminating a bacteria’s capability to form an anti-body against the protective coating.

The cell wall of a microbe is about as thin as a soap bubble. Imagine the antimicrobial barrier created by the Bacteria Shield™ – as a lawn with countless blades of grass pulling at that soap bubble until it reaches the grass and pops.


The Bacteria Shield™ is a BONDING organosilane quaternary Antimicrobial Surface coating that lasts up to 12 months (see White Sox letter in references) on applied surfaces and objects. Our Bacteria Shield™ physically ruptures the target organism’s cell membrane on contact.

Bacteria Shield™ molecularly bonds to a treated surface (covalent bonding), penetrating the substrate, thus making 100% and 360° of the surface itself antimicrobial against a broad spectrum of surface damaging virus, fungi, bacteria, algae, and yeast.

The Science: 3 Key components

1.Bio-Static Quaternary Compound:

  • Bacteria Shield™ carries a positive charge attract to universally negatively charged bacteria (by law of nature), pulling in the bacteria and disrupting the bacteria cell wall providing an antimicrobial protection by impregnating itself  into organisms and the surface.
2.Silane Chemistry:
  • Is the basic building block of the  silicon chemistry. Silicon bonds tenaciously to other inorganics such as glass and steel (hard surfaces), Silicon will bond tenaciously to organic polymers as well. Therefore this creates an added level of surface “adhesion”, when combined with the covalent bond chemistry. Silicon also prevents microbes from being able to colonize on surfaces.

3.Covalent Bonding: example: Water (H2O)
  • Bonding between atoms by sharing electrons which binds the atoms together into a singular unit, thus providing for the long-term durability to remain on surfaces with just one application. 2 hydrogen atoms share their single electrons with Oxygen atoms, which shares it own electrons in return.

Turbo-Flo Spraying Technology: Electrostatic Wrap-Around

Electrical charging causes an attraction force between the sprayed drops and the target surfaces. The electrical charge on the spray droplets is small but the force of attraction to the surface is strong since the sprayed particles are lightweight. The electrical force which pulls the spray towards the surface is 40 times greater than the force of gravity. This means when the droplets approach the target surface, they will reverse direction and move upwards against gravity. The electrostatic wrap-around phenomenon occurs as droplets move quickly towards the target. The level of charge is important for the electrostatic effect. Other electrostatic sprayers have not been able to produce a charge high enough to give a significant electrostatic benefit. Sterile Environments spray nozzles produce the highest charge level of any electrostatic sprayer on the market and work with most classes of chemicals.

B.) Bacteria Shield™ cures and polymerizes to 100% of surface areas while drying. The coating get into every crevice, the undersides & backsides; and stays there for 1+ years – all day every day.










C.) Bacteria Shield™ powered by mPerial and mPale™ dries and bonds CLEAR (photo to left) upon surfaces within 1 to 10 minutes. There is no residue and it can not be removed by other cleaners or bleach once it is bonded to the surface.


Bacteria Shield™ Coating compared to Other Spray n’ Wipe Antimicrobials:

THE BIG DIFFERENCE: 1+ Years of protection with 1 application vs. 90 Days of protection (competitors) with 1 application.

Our type of antimicrobial technology is commonly referred to as non-leaching because it doesn’t come off the surface to work. The Bacteria Shield™ can be impregnated into or applied to the product’s surface, providing durable antimicrobial surface protection.

When our Bacteria Shield™ antimicrobial products are applied to a surface or fabric, billions of tiny silane molecules or, “microbial defenders”, are delivered to the surface and a multi-month antimicrobial barrier is created.

Bacteria Shield (non-leaching vs. leaching) antimicrobials:

To understand the significance of our unique bio-static non-leaching antimicrobial technology it must be compared to antimicrobial products that are leaching. Common leaching antimicrobial products use heavy metals, such as silver or copper, to essentially poison microbes. In order for this to work some of that heavy metal or poison must come off the surface each time it destroys a microbe, leaving behind less antimicrobial effectiveness and introducing heavy metals into the environment. Sterile Environments antimicrobial products on the other hand destroy microbes by tearing them apart with force and puncturing them, meaning the antimicrobial barrier is as strong for the millionth microbe it encounters as it was for the first. The chart below helps summarize other key factors that make SD Pro, SD ST and SD Clean far superior to any leaching, antimicrobial product on the market.

Bacteria Shield™ Non-Leaching Products

Leaching Antimicrobials Using Silver or Copper


Needs less time to work. It takes less time to destroy a microbe by tearing it apart and puncturing it than it does to slowly poison it. Needs more time to work. Silver or copper take a long time to permeate the cell wall of a microbe and then slowly poison it.

Microbial Adaptation

Microbes can’t adapt, or create “super bugs” like MRSA, on the antimicrobial force field applied on surfaces and fabrics by the Bacteria Shield™ Over time – microbes can adapt to poisons like silver or copper, creating “super bugs” like MRSA.

Antimicrobial Efficacy

Creates an antimicrobial barrier that does not come off the surface or fabric to destroy bacteria’s cell wall, meaning antimicrobial coating is as strong for the millionth microbe it encounters as it was for the first. Must dissolve off the surface or fabric each time it poisons a microbe, leaving behind less antimicrobial effectiveness for future microbial encounters.

Environmentally Friendly

Yes. Bacteria Shield™ creates a non-toxic, environmentally friendly antimicrobial barrier on surfaces that does not come off the surface. No. Silver and copper based antimicrobial products leach heavy metals into the environment.


Bacteria Shield™ has been used safely and effectively in all areas of construction to plastics as well as in hospital applications. The following information has been prepared in response to numerous requests for a list of microorganisms against which the technology is effective. They were selected to provide a test spectrum which is representative of all significant types and varieties of microorganisms.

Laboratory testing is performed in a controlled environment and may or may not be interpreted as eliminating, controlling, minimizing or otherwise affecting health conditions which maybe associated with specific organisms.

Bacteria Shield™ Coating is Natural and Green

Bacteria Shield™ (mPale™) formulas can be incorporated in a variety of materials, including powder coating, gel coats, latex paints, polymers, fabrics, paper products, and wood. Bacteria Shield™ can also be applied to multiple areas such as: kitchen & bath, indoor/outdoor surfaces, plastic, stone and metal surfaces, automotive surfaces, footwear, pet odor areas, laundry, and carpet.
