Long Term Antimicrobial Coating

Preserve, Prevent, Protect


Antimicrobial coating technology is a rapidly growing industry. This technology can be used to inhibit microbial growth on different surfaces. This coating can be used on frequently touching surfaces, so it will greatly help in preventing contamination. This coating can be easily sprayed on any surface to make an antibacterial coating over the surface. This is a better solution, so you no need to use powerful disinfectants to clean your surface areas frequently.

ASN Guard Long-term Antimicrobial coating is a surface protection coating that imparts a durable, long-lasting shield to various surfaces against microbial attack. The surface treated with this coating is not affected by infectious bacteria, viruses, fungi, and mildew. It also protects the surfaces from dust and stains, and makes them easy to clean and decontaminated.

Why antimicrobial products are needed.
An antimicrobial agent can be used to maintain the surfaces on disinfectant mood for a longer duration. This product can be used in hospital setups, homes, workplaces, and most importantly to clean the environment of immune-compromised patients.

The antimicrobial coating formulation contains Quaternary ammonium compounds as the main active ingredient. This top-grade antimicrobial protectant has demonstrated efficacy in disinfecting the notorious SARS – Coronavirus and other highly resistant viruses.

ASN Guard Antimicrobial Coating is based on a single component that is harmless and eco-friendly. It is available in two formulations, i.e.

The coating that performs up to 30 and 90 days.

The effectiveness of both these coatings, however, depends on the bio-load (level/ chances of contamination of a surface) and abrasion (rough use of a surface).

Surfaces can be recoated as needed.

Complete Surface Protection (including protection from molds)

ASN Guard All Surface Antimicrobial Coating is completely resistant to acidic, alkaline and reactive solvents. So the antimicrobial activity can prevent the spread of various infections.
Additionally, it protects the surfaces from the attack of a broad range of fungi. Also effective against molds, mildew, algae and resistant biofilms.
Since coating imparts protection to surfaces thereby reducing maintenance cost. Overall a cost effective solution.
Coating remains intact for up to 30/90 days giving 24hrs protection, which however depends on the use of surface and level of abrasion.

Broad Spectrum Antibacterial Coverage
ASN Guard All Surface Antimicrobial Coating provides continuous long term protection coverage against a broad range of bacteria.
How do antimicrobials work?
Its long term effectiveness is due to its physical antimicrobial action and not the chemical one. They disrupt the cell of bacteria or virus thus making them inactive.
When tested for its antimicrobial efficacy, the bacterial concentration of coating treated surfaces after 24hrs contact time, was found to be zero, demonstrating 100% eradication of pathogenic bacteria.
Does antimicrobial kill bacteria?
ASN Guard Antimicrobial Coating was found to be absolutely effective against microbes including bacteria and virus even after thirty wash cycles on porous surfaces.

99.99% proven efficacy in killing Stubborn (Non-Enveloped) Viruses
Avoiding the contamination is the best measure to prevent from corona virus. An effective antimicrobial product can protect us from contaminating the virus.
The active ingredient QAC in ASN Guard Antimicrobial coating is effective in killing all three types of viruses as per EPA guidelines, i.e.

Enveloped viruses, e.g. Coronavirus, Herpes virus, Influenza virus or Hepatitis virus.
Large Non-enveloped viruses, e.g. Adenovirus, Rotavirus, or Papillomavirus.
Small Non-enveloped viruses, e.g. Escherichia MS2 virus*, Enterovirus, or Rhinovirus.

* Escherichia MS2 (ATCC 15597 B1) belongs to the family of small non-enveloped viruses, which are highly resistant infectious organisms and are most difficult to inactivate. This icosahedral virus lacks lipid envelop therefore shows high level of stability against chemical disinfectants and environmental stressors such as temperature fluctuations, desiccation and osmotic pressure.

Deactivates COVID-19
According to EPA’s policy, a disinfectant is considered to be effective against an emerging pathogen (i.e. COVID-19) if it demonstrates efficacy (in level of EPA claimed limits) in killing more resistant virulent species (i.e. small non-enveloped viruses).
ASN Guard Long Term Antimicrobial Coating was found 99.99% effective in killing MS2 bacteriophage and was considered suitable for deactivation of surfaces for COVID-19.
Since SARS COV-2 strand is not commonly available in labs for testing, so as per EPA Guidelines OCSPP 810.2200 and OCSPP 810.2000, all third party lab tests were conducted on viruses where ASN Guard Antimicrobial Coating was found to be successful virucide for deactivation of COVID-19

Invisibility and Inertness
ASN Guard All Surface Antimicrobial coating is completely transparent and inert giving a smooth sheer look to the coasted surface
The coating dries quickly and is permeable to air.
No obnoxious chemical smells.

In addition to giving anti-microbial protection, the coating imparts additional protection to the coated surface from dust, oil and water.
It makes surface easy to clean and disinfect requiring little use of expensive cleaning agents or harsh chemicals.

Feature Durability

Easy applicability
The coating can be applied using spray equipment, pump or simple hand sprayer, immersion, padding or with the help of roller.
To ensure even spread on hard or tough surfaces, a microfiber cloth can be used for uniform coating spread after spraying.

Curing Time
ASN Guard Antimicrobial Coating stabilizes within minutes after application and surface is ready for medium usage. Maximum adhesion to the surface may take 8-12 hrs.

The antimicrobial ingredient complies with WHO and EPA standards
ASN Guard Long Term Antimicrobial Coating contain Quaternary ammonium compounds (QAC) in a concentration of 0.65% w/w which is higher than the percentage recommended by WHO for Anti-COVID disinfectants. The cationic nature of QAC neutralize the negatively charged viral proteins thus rendering them non-virulent.

World Health Organization (WHO) Guidelines:
COVID-19 is susceptible to disinfectant Quaternary ammonium compounds in concentration of 0.5%. source/coronaviruse/laboratory-biosafety-novel-coronavirus-version-1-1.pdf

ASN Guard Long Term Antimicrobial Coating can be coated seamlessly on the following surfaces:

  • Wood
  • Rubber
  • Glass (all kinds)
  • Stone or Granite
  • Plastic and Vinyl
  • Steel and other metals
  • Textile made of natural or synthetic fiber


Directions for Application

  • The surface to be coated, must be dry, clean and unsealed. Any dust, soil, oil or sealer on the surface can negatively affect the efficiency of coating. Test surface is an inconspicuous area before application.
  • In case of textiles, washing must be done to remove any dirt, additives, or washing agents before application of coating. Also a smooth coating spread and its absorption in the cloth fiber must be ensured.

ASN Guard Antimicrobial FAQ


What is Antimicrobial Technologies

Antimicrobial technologies minimise the presence of bacteria, mold, and fungi. Antimicrobial substances offer a greater level of product protection by continuously inhibiting the growth of microbes on surfaces for very long periods of time. The broad spectrum performance of antimicrobial substances makes them perfect for use in hygiene critical environments such as schools, hospitals, and commercial kitchens.


What is Long Term Antimicrobial Surface Coating

ASN GUARD Long Term Antimicrobial Coating  is a breathable, ecologically sound, ready to use, single component, molecular coating that forms a long lasting, durable, hygienic barrier on metals, textiles (natural and synthetic), wood, plastic, walls etc..

The treated surface becomes resistant to mould, mildew, bacteria, virus, dirt and stain resistant, super hydrophobic, oleo phobic and allows the easy cleaning & removal of soils. Surface become antimicrobial, killing bacteria continually at a typical rate of 99.99%.


How does ASN Antimicrobial Coating kill the pathogen

ASN Antimicrobial Coating are cationic (positively charged) ions which bind to the negatively charged outer membranes of germs; breaking down the membrane resulting in the killing or inactivation of those germs. End result a better quality of air circulating in the environment  with the applied solution.

ASN Antimicrobial Coating containing formulations are effective against a wide range of bacteria, virus and fungi, including many pathogens of concern found in everyday settings from our homes, schools, and work to hospitals and food service establishments.


Why should I use ASN Guard Antimicrobial coating instead of other traditional disinfection methods?

Traditional disinfectant solutions are only effective for a very short period of time and once dry, their kill rate diminishes to zero very quickly. ASN Antimicrobial coating eliminates the risk of infection from cross-contamination 24/7/365 for at least 90 days after treatment.
