FAQs

How does the penetrexx® antimicrobial technology work?

The active ingredient in the PENETREXX® ANTIMICROBIAL forms a colorless,odorless, positively charged polymer, which chemically bonds to the treated surface, think of it as a layer of electrically charged swords. When a microorganism comes in contact with the treated surface, “spike” 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. Normal cleaning of treated surfaces is necessary to prevent buildup of dirt, dead microbes, etc., which could cover the “spikes,” prohibiting it from killing microorganisms.

What is the purpose of the silane portion of the molecule?

Silanes are extremely efficient bonding agents, which can be coupled to other molecules and then used to permanently bond those molecules to a target surface. This process modifies surface properties of building materials and transforms them to a material that will not support microbial growth. In other words, it is the “glue” that holds the “spike” to the surface.

Is the penetrexx® antimicrobial technology a quaternary compound?

PENETREXX® ANTIMICROBIAL is an organosilane, but part of the molecule is a quaternary amine. Unlike traditional quaternary disinfectants, which have a very short effectiveness and a limited kill spectrum, PENETREXX® ANTIMICROBIAL provides extended protection, and controls a very broad spectrum of microorganisms (including Gram (+) and Gram (-) bacteria). As an added benefit, it is easier to use.

What is the difference between penetrexx® antimicrobial and other antimicrobials?

Conventional products are absorbed into 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. Most commercial antimicrobials used for treating building surfaces do a great job of getting a quick kill on bacteria and fungi, although most have a limited spectrum of effectiveness. The PENETREXX® ANTIMICROBIAL technology takes a totally unique approach. It provides an effective antimicrobial barrier, providing extended control of growth on treated surfaces between standard cleaning and disinfecting protocol. The surface itself is modified to make it actively antimicrobial, with no need to reapply the product for 30 days or more.

Is penetrexx® antimicrobial permeable to moisture?

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

Does penetrexx® antimicrobial give off gases during or after application?

No, PENETREXX® ANTIMICROBIAL does not volatilize, dissipate, or leach onto other surfaces or into the environment. PENETREXX® ANTIMICROBIAL’s chemistry polymerizes where it is applied and forms an antimicrobial barrier on the surface.

How long does the treatment last?

The cured antimicrobial is non-volatile, insoluble, and non-leaching. A treated surface’s life span depends on a number of factors, not the least of which is surface preparation. Treating a dirty or unstable surface decreases the effectiveness of the antimicrobial. Abrasive or caustic (pH 12.0) cleaners can shorten the effective life of a treated surface, therefore the product should be reapplied every 30-90days, depending on these factors.

What kind of preparation is needed for treatment?

We recommend disinfecting surfaces with an EPA registered List N disinfectant prior to application of PENETREXX® ANTIMICROBIAL. However, PENETREXX® ANTIMICROBIAL can be applied to any clean surface.

How do you handle contaminated surfaces?

Microbes can be extremely hazardous. Severe contamination with hazardous organisms may require extreme cleaning protocols similar to those for asbestos removal. For normal decontamination: solid surfaces should be thoroughly cleaned before applying PENETREXX® ANTIMICROBIAL to the surface.

How is penetrexx® antimicrobial applied?

For everyday applications Clearstream’s® PENETREXX® ANTIMICROBIAL can be applied with our easy to use 32 oz. surface spray. We are happy to provide application tips for the treatment of large facilities and / or surface areas.

Is alcohol-free hand sanitizer as effective as alcohol ones?

Yes, In a study published by The Journal of Hospital Infection, alcohol-free alternatives were tested and found effective against SARS-CoV-2. A copy of this published study and additional studies or technical information concerning alcohol-free hand sanitizers is posted under the "Science" tab on this website.

Does the extended protection of penetrexx mean I can clean and disinfect less often?

No, Extended protection means Penetrexx offers antimicrobial protection between your regularly scheduled cleanings and disinfectings, but should not replace your standard cleaning/ disinfecting protocol. This is why we refer to it as the “Missing Piece” of your existing protocol.
