Antimicrobial Coatings For Ductwork: A Long Term Solution

When an HVAC system’s ductwork becomes contaminated with mold, this can trigger allergies and asthma, and cause even more serious health issues for people in the building. Expensive HVAC repair or replacement costs are likely and, when dealing with ductwork problems, this process can disrupt operations throughout the facility.

Silver Bullet AM™ with Agion® Technology is a powerful solution! In a recent study by the University of Tennessee, Silver Bullet AM™ was able to completely eliminate the spread of dangerous pathogens. In another study conducted by the University of Arizona, Silver Bullet AM™ was proven to be 99.9 percent effective against a variety of destructive bacteria.

Just one application provides long-lasting surface protection against a host of microbes that include E. Coli, legionella, listeria, salmonella, and more.

Silver Bullet AM™ for Antimicrobial Ductwork

Silver Bullet AM™ with Agion® Technology contains an EPA registered silver/copper ion antimicrobial compound that can protect coated surfaces from a broad spectrum of bacteria, mold, mildew, algae and fungi. This high gloss, high durability, water-based epoxy works by disrupting the reproduction and inhibiting metabolism of microbial cells.

Two Application Methods

This antimicrobial ductwork coating can be purchased in one gallon or five gallon buckets in clear, black, or white. Silver Bullet AM is also available as a clear HVAC antimicrobial spray.

No matter which application method you prefer, this coating system is ideal for HVAC ductwork, as well as in areas where severe chemical washing occurs, such as handrails, restrooms, food service areas, and commercial door handles. The stable ion exchange process of this product represents a significant improvement over standard organic antimicrobials that dissipate rapidly.

Silver Bullet AM™ is water-based and VOC-compliant, formulated for long-term performance in today’s challenging indoor settings. It can be applied with ease to metal, and concrete surfaces, dries within a few hours (20-60 minutes tack-free), and cures completely within a week.

How Mold Gets Spread

HVAC systems circulate air to warm up a building in winter and cool it down in summer. Through this process, mold spores from the building’s walls, ceilings, and surfaces get pulled into the HVAC equipment. Once they get into the ductwork, the mold itself gets circulated along with the air, which distributes these spores throughout the building. Plus, in damp places within the HVAC system itself, mold can mix with dust and other contaminants, which then can cause a problem within the equipment. In these situations, bacterial growth can also occur, compounding the issues.

As the HVAC ductwork becomes increasingly more contaminated with mold and bacteria, it naturally spreads even more of these substances throughout the facility. Once the contamination reaches a certain level, cleaning it becomes too challenging and the HVAC system typically needs to be replaced.

Antimicrobial Coatings as a Proactive Approach

Preventative maintenance seldom addresses mold that’s growing deeply within the ductwork where it can’t be seen. There, it can continue to grow without interruption, despite the routine maintenance that’s being done in more easily seen areas of the duct system.

Fortunately, when the issue of mold and bacterial contamination is proactively addressed, there is a highly effective, long-term solution: HVAC antimicrobial coatings. Although it’s possible to order new ductwork that’s already been coated with antimicrobials, factory-coated duct systems can be expensive and delivery times can be long. Shop-applied antimicrobials are a cost- and time-efficient solution.

When HVAC protective coatings are applied to new ductwork as a preventative measure, additional benefits include: extending the life of your ductwork and less maintenance by making it easier to keep your ductwork clean—which results in overall cost-savings during the lifetime of your HVAC system.

HVAC Antimicrobial Coating FAQs

How safe is Silver Bullet AM™?

Equipment that’s been coated with Silver Bullet has been put through rigorous independent laboratory studies under intense test conditions. Results prove how coatings of this product can withstand extremes of both temperatures and chemicals to continue to perform well by significantly reducing contamination.

What type of testing has been done on Silver Bullet AM™?

Testing has been both rigorous and independent. In these tests, equipment has been coated with Silver Bullet and then studied under intense conditions, both in terms of temperature and of the chemicals involved in cleaning coated areas. Results prove that this antimicrobial surface coating continues to significantly reduce contamination, even under extreme temperatures and chemical use.

What is the active ingredient(s) in this formulation?


What are the benefits of using silver to reduce microbiological contamination?

First, it’s a safe and natural solution, which allows for environmental compatibility while having proven effectiveness against microbiological contamination and propagation, with bacterial resistance, as well. The formulation is also highly durable with thermal stability while also being corrosion resistant—and it also has an effective life expectancy.

What makes this antimicrobial coating for ductwork so effective?

Silver! That’s the active ingredient in Silver Bullet’s highly durable and corrosion resistant formulation. Silver is a safe, natural solution with proven success to reduce microbiological contamination and propagation. Benefits of using silver include the substance’s:

  • Thermal stability
  • Environmental compatibility
  • Effective life expectancy
  • Bacterial resistance

Silver works especially well because of its ability to inhibit reproduction of organic materials, such as mold. It interrupts the metabolism and disrupts cell wall functions of a number of types of mold, bacteria, and yeast. Plus, the stable ion exchange that takes place is significantly more effective than traditional organic antimicrobials that rapidly dissipate.

How quickly can Silver Bullet work? How long lasting is it?

This compound has been demonstrated to work within a matter of hours. Once applied, it can maintain maximum performance for a period of years through a controlled release of silver and copper ions via the use of a zeolite carrier. Its application also suppresses future contamination.

How does the HVAC antimicrobial spray work?

This is a waterborne product with Agion antimicrobial compound protection in the formula to protect against microbial growth. A leading HVAC manufacturer, Carrier, uses this coating technology for HVAC systems in hospitals, as well as in schools, restaurants, and other facilities where mold, bacteria, and fungi is a concern. Besides being used on metals, Agion antimicrobial compounds can be incorporated into fabrics, fibers, and molded plastics, with the controlled release of silver ions able to continue to suppress the growth of microbial substances.
