MicroShield treated hardware reduces bacterial growth quickly!

* Consult SARGENT for specific test results.

MicroShield products are ideal for installation in countless hardware applications where vigilance in the war against bacteria and mold is critical, such as hospitals, assisted living facilities, clinics, laboratories, offices, schools and daycare facilities to name a few.

This true industry innovation puts SARGENT on the cutting edge! The Agion antimicrobial compound is a silver-based antimicrobial agent that is incorporated into the MicroShield coating. This coating is effective against a broad spectrum of bacteria.

What is the Agion antimicrobial compound?

The Agion antimicrobial compound is an inorganic material that incorporates the natural protection of silver. It has been proven to be successful in controlling the spread and growth of many types of bacteria, mold and mildew.

How does it work?

Silver ions are slowly released from the antimicrobial compound to the surface of the treated hardware, inhibiting the growth of destructive microbes.

Is Agion safe?

The Agion antimicrobrial compound is safe and proven non-toxic. The Agion antimicrobial is registered with the EPA, the NSF and is even FDA listed for use in medical and food preparation equipment.

How quickly does MicroShield work?

The Agion antimicrobial in MicroShield is always working to protect the treated surface. For most types of microorganisms, the majority of contaminants will be gone in as little as 20 minutes.


MicroShield will last for the life of the hardware.

How long will it last?

The MicroShield coating is permanent under normal wear and tear.

If the MicroShield coating is scratched, will the treated surface still be protected?

A small scratch through the coating will not adversely impact the product from an efficacy standpoint. Silver ions contained within the Agion antimicrobial compound can still diffuse and migrate to the bacteria or microbes within the scratch. The active silver can “bridge” the gap. Wide scratch patterns may reduce the amount of antimicrobial product available to inhibit the growth of microbes.

How do I know that the product is still inhibiting the growth of microbes?

Procedures have been developed to show that the Agion compund continues to inhibit the growth of microbes. (Available upon request)

Does this mean that I will no longer have to clean my hardware?

The normal cleaning regime appropriate to your environment is recommended. The MicroShield coating provides a cleaner surface and should be viewed as a second line of defense in the fight against bacteria, mold and mildew.

How should the product be cleaned?

The surface of the treated product may be cleaned with a mild detergent and then allowed to air-dry or dried with a soft cloth. As with any powder coat finish, harsh abrasive cleaners should be avoided to prevent coating damage.

Is anyone using this product today?

Stainless and carbon steel products treated with coatings similar to MicroShield, containing the Agion antimicrobial compound, have been used in Japan for about 7 to 8 years in appliance, food and restaurant equipment. In the US, this new antimicrobial compound is used in footwear, water bottles, clothing, food preparation surfaces, HVAC products and medical applications. SARGENT is the first and only full line manufacturer of locks, exit devices, door closers and key control systems to offer their product lines coated with MicroShield, containing the Agion antimicrobial compound.

What competitive products exist?

There are no comparable products known to be on the market today offering the unique properties of the Agion antimicrobial compound. Other products that do offer antimicrobial protection base it on less desirable organic compounds or antimicrobial metals which are ineffective, impractical, unsafe or financially unfeasible. The Agion antimicrobial technology in MicroShield incorporates the natural protection of inorganic silver. Silver has been used for centuries to store and preserve water, wine and milk. SARGENT is the only commercial architectural hardware manufacturer of locks, exit devices and door closers to offer this innovative and effective new finish coating.

How do I get the product?

SARGENT offers the product through their authorized distributors. For additional information on how SARGENT products coated with MicroShield can ensure the best product selection for each building's unique requirements, contact SARGENT at 1-800-727-5477.
