Long-Term Antimicrobial

Surface Coating

Trusted technology in cleaning, disinfecting, and shielding your spaces


The current global pandemic has stressed the economy and caused many businesses to change the way they operate or close all together. This has created demand for alternative solutions to help stabilize consumer confidence and provide an overall safer environment for people to congregate in.


The current cleaning and sanitation process is toxic, time-consuming, inefficient, and temporary. Surfaces disinfected with traditional chemicals can quickly become re-contaminated.

What is ASN GUARD?

ASN GUARD Antimicrobial Surface Coating utilizes revolutionary molecular technology in combination with a special blend of quaternary ammonium compounds that act as antimicrobials in a stabilised self-assembling thin layer surface coating.

The coating on an object prevents viruses and bacteria from attaching to surfaces. Simply spray the coating on any surface. The liquid will quickly disinfect the surface and within minutes will create a safe long term antimicrobial coating.

ASN GUARD aims to provide consumers the latest technology for Antimicrobial Coatings as they have been thrust to the forefront in the fight against surface contamination worldwide, inhibiting the growth of microorganisms, including bacteria, viruses, yeast and fungi.

How It Works?

Unlike traditional disinfectants that use poisons to create cidal kills (attacking by killing from inside with poison) ASN GUARD deploys a mechanical kill which punctures a cell’s membrane then applies a positive charge which neutralizes the cell.

Overview of the Mode of Action and Functionality of ASN GUARD


Nano Base

This part of the molecule creates the permanent covalent bond to both other molecules and the surface itself.

Positively Charged

All elements in the natural world are neutral or negatively charged. This holds true for microorganisms. The positive charge of ASN GUARD creates the laws of attraction and draws the microorganisms towards it.

Long Carbon Chain

This serves as the “blade” of the molecule. As ASN GUARD pulls the microorganism down the long carbon chain pierces the cells wall thereby altering its ability to properly function. If the cell happens to survive this disruption ASN GUARD applies the positive charge which finally neutralizes the microorganism.

*Important Note:
As such, ASN GUARD treated surfaces must be routinely cleaned to remove organic matter and ensure the coating is at the top of the surface to properly work. ASN GUARD stops cross contamination with perpetual micro biostatic and antimicrobial surface protection.

Daily Maintenance

Daily Maintenance and Cleaning Recommendation:

For this ASN GUARD Daily Clean Disinfectant Spray (Listed : List of Household Products and Active Ingredients for Surface Disinfection of the COVID-19 Virus) can be used.
ASN GUARD Daily Clean Disinfectant Spray is compatible with the ASN GUARD Long Term Antimicrobial Surface Coatings.

SOP for Best Disinfection

Steps to follow: Simple 3 Step Protocol for Best Results


General daily cleaning is a must to rid the surface of dirt and oils. This step of cleaning is to make sure the surface is free of all soil, dirt, oils, and sealers. Textiles must be washed to remove any dirt, additives, or washing agents prior to application. Please remember clean does not mean disinfected from bacteria and virus.

ASN GUARD Daily Clean Disinfecting Spray


Surface disinfection is to kill disease-causing pathogens including microscopic bacteria and viruses.


Post disinfection the surface however is exposed to recontamination and cross contamination.

ASN GUARD Long Term Antimicrobial Coating


Surface coating is done on a clean and disinfected surface to create a perpetual long term antimicrobial surface.


Application may be done by use of spray equipment, pump or hand sprayer.
Suggested is Electrostatic spray equipment.


Cover the surface with a thin even mist of the coating. Then just let it dry.


Slightly dampen a microfiber cloth with the coating formula and lightly buff away any residue on glossy surfaces such as glass, in case spotting is seen from the coating. Buffing in this manner will not remove the coating from the surface.

Effective Against COVID -19 Testing

Regarding Claims of being effective against COVID – 19: (Test Organism: Human Coronavirus 229E)
Global guidelines suggest including that of EPA (USA), TGA (Australia) and NEA (Singapore) to test product on Human Coronavirus 229E to claim effectiveness against COVID – 19.

ASN GUARD Antimicrobial Surface Coating passed the test on Human Coronavirus 229E (ATCC VR-740)
Result: Viral reduction exceeding 4 log10 (≥ 99.99%).

ASN Guard FAQ questions

ASN Guard antimicrobial coating uses cutting edge technology consisting of Quaternary Ammonium Compounds that disinfect and shields surfaces from disease-causing microbes including viruses, bacteria, mold, and fungi. Once the coating is applied on any surface, a nano scale layer is formed on the surface with microscopic needles which mechanically punctures and kills any virus or bacteria strands that falls on the coated surface. This process interrupts the essential function of the cell membrane and the protein activity, ultimately eliminating the virus strand. During the interaction with the cell membrane of virus, the coating remains intact and retains its antimicrobial ability, hence providing long term antimicrobial functionality.
Yes, it is effective against SARS-CoV 2. ASN Guard is also effective against other viruses, bacteria, mould, and fungi.
ASN guard 30 and 90 day protection cleans, disinfects, and shields from contamination. Conventional disinfectants such as alcohol based, chlorine based, phenol & chemical based disinfectants only cleans and disinfects surfaces and are opened for cross contamination almost immediately after cleaning and disinfection. ASN Guard anti-microbial continues to provide ongoing antimicrobial surface between the cleaning cycles.
ASN guard daily clean works as a disinfectant. ASN guard 30 day protection offers 30 days of anti-microbial surface coating between cleaning cycles, whereas ASN guard 90 days offers protection on coated surfaces for 90 days.
It will depend on the type of ASN guard that you have purchased. ASN guard daily clean is meant to use daily as a disinfectant, while ASN guard 30 day protection will need to be reapplied every 30 days and ASN guard 90 day-protection will need to be re-applied every 90 days. If it is high traffic area, 30 day protection is recommended as it needs to be reapplied more often.
No, it does not, especially when used in conjunction with ASN guard daily for cleaning and disinfection as it will ensure that the coating is maintained. ASN treated surfaces must be routinely cleaned to remove organic matter and ensure the coating is at the top of the surface to properly work.
ASN guard can be used in health care settings (hospital, medical/dental clinics, and aged care facilities), public transport, F&B establishments, hotels, day care centers, offices, shops and in your own home.
ASN guard can be used on metal, steel, wood, plastic, vinyl, natural fiber textiles, synthetic textiles, stone, and granite.

ASN guard is safe for use as a coating on food contact surfaces such as counter tops in kitchen and table tops in dining area. It has been tested under the Singapore Food Act, FDA and EU Regulations. However, ASN Guard cannot be sprayed directly on food.

Yes, it is safe to eat as ASN guard is food safe and non-toxic. It has passed the Singapore Food Act, FDA, and EU Regulations.
No, as its main purpose is for surface disinfection and anti-microbial coating. Instead, you can use Purple – our hand sanitizer which uses the same technology and is also hydrating for skin as it does not contain any alcohol.
ASN guard is noncorrosive and odorless so there will no damage or smell to surfaces it is sprayed on. In fact, the coating offers additional protection against most stains.
Yes. It is biodegradable and does not accumulate in the environment.
No. It is easy to use by yourself using our sprayer.
