Arc Flash’s Nano Tio2 Application in Action (Malaysia)

You have seen what Arc Flash’s nano tio2 can do. Have you any idea how its being applied? Our nano tio2 is being applied using the direct spray on system. The tool that we use is not just an ordinary spray paint gun you can get in the market, but we are using the ELECTROSTATIC SPRAYER SYSTEM.

Here is an example of a typical application for Arc Flash Corporation’s Nano Tio2
Arc Flash’s Electrostatic Application

Nano Coating Using Electrostatic Technology – How it works

Nano coatings are composed of extremely tiny droplets. Electrostatic application of a nano coating employs the law of physics describing the electrostatic interaction between electrically charged objects. This law is behind why metal filings are drawn to a magnet, lint is attracted to your clothes or dust clings to the screen of your television. These are all examples of Coulomb’s law in action – opposite electrical charges attract and “like” charges repel. (These principles of physics were first published in 1783 by French physicist Charles Augustin de Coulomb.)
In numerous commercial, industrial and agricultural spraying operations, electrostatic forces of attraction significantly improve the deposition (coating) of charged droplets onto target surfaces. Such operations include liquid and powder paint coatings, electrostatic precipitation of air pollutants from stacks, electrostatic spraying of agricultural pesticides onto field crops and orchards, xerographic copying, ink-jet printing, textile flocking, and more recently, disinfection, sanitization and decontamination applications.

Droplet Control & Droplet Size

Common to all these electrostatics based operations are droplet control and droplet size. Droplet control consists of first, imparting an appreciable net electrical charge onto the individual droplets (e.g., 5-15 mC/kg charge – to mass), and secondly, propelling the charged droplets to the target surface.
Droplet size is the result of shattering, or atomizing, the jet of spray coating into much smaller droplets. Droplet sizes are measured in microns. The most common term used to describe droplet size is Volume Median Diameter (VMD). VMD refers to the midpoint droplet size (mean), where half of the volume of spray is in droplets smaller, and half of the volume is in droplets larger than the mean. A VMD of 50, for example, indicates that half of the volume is in droplet sizes smaller than 50 microns, and half the volume is in droplet sizes larger than 50 microns.
A micron is 1/1000 millimeter, or about 1/25,000 of an inch. In comparison, a drop of water is about 250 to 300 microns in size, a human hair is about 100 microns in diameter. Droplets 50 microns and less are generally considered to be aerosol droplets. The range and size of droplets in any given spray has tremendous influence on coverage, volume of spray used, retention, and runoff. When droplets greater than 150 microns strike target surfaces, they become flattened, but their kinetic energy is such that they retract and bounce away. Small droplets are better retained as they lack the kinetic energy to overcome surface energy and viscous changes that occur on impact and do not bounce away.

Optimum Droplet Size

The optimum size is generally considered to be between 40 and 100 microns. Droplets in this range cover more surface area, require lower volumes, are less susceptible to bounce back and runoff than those larger than 100 microns. The surface area of a liquid is greatly increased when broken into small droplets. The volume needed to cover target surface decreases proportionally with droplet size. Even small changes in droplet diameter make big differences in droplet weight. An increase in droplet diameter from 150 microns to about 190 microns doubles the droplet weight. An increase in droplet diameter from 150 microns to about 240 microns increases the weight 4 times. Doubling the diameter to 300 microns increases its weight, and also its volume, by 8 times.

Charged vs Uncharged Droplets
When droplets are uncharged, neither the droplets nor the target surface has any influence on the other. Sprayed droplets are principally influenced by forces generated by the spraying device (pressure, air flow) and by external forces of gravity and air drag. Uncharged droplets are more susceptible to air currents in the spraying area while charged droplets are less influenced by air currents.
An electrostatic sprayer induces an electrical charge onto droplets creating an attractive force between charged droplets and targets. This electrostatic force overrides gravity and inertia to pull droplets out of their paths – up, down or sideways – to the closest surface.
To compare influence, the electrostatic force on charged droplets is up to 75 times greater than the force of gravity. Electrostatically charged droplets are also influenced by the sprayer’s mechanical forces, however, once they reach the vicinity of the target, electrostatic forces take over to a very large degree.
In water based coatings, the water carries the electrical charge. Charged sprays, unlike uncharged sprays, resist coalescing into larger droplets both in transit and deposition. As each charged droplet is deposited on a surface, electrical charges balance out at that site, making it no longer attractive to other charged droplets. The droplets following are pulled instead to the rest of the surfaces which remain attractive.

Atomization & Induction Charging
A typical droplet of spray from a conventional air-blast applicator is around 250 microns in size. A typical droplet of spray from an electrostatic sprayer is around 40 microns. In the nozzle of an electrostatic sprayer the coating liquid passes in very close proximity (but does not contact) a positively charged electrode, inducing a negative charge (excess electrons) in the grounded liquid stream. The stream of coating liquid, with its excess electrons, is combined in a shearing action with a near sonic velocity jet of air, shattering (atomizing) the coating liquid into droplets 30 to 40 microns in size.

Shattering the liquid stream breaks the droplets free from the grounded liquid stream and traps the excess of electrons. As the electrically charged droplets exit the nozzle, they create a charged field plume that is strongly attracted to the targeted object. The charge on the atomized droplets remains until discharged on a grounded object or the water content of the droplet evaporates.
Induction charging is based on the principle that a field charge, created within the plume, is presented to a grounded target. It is this field charge the plume creates that really makes an electrostatic sprayer so effective. The charge is small, but the force attracting the coating plume to the target is substantial, up to 75 times the force of gravity.

As the target sits with a neutral potential the proximity of the field charge induces a strong attraction. The droplets actually reverse direction and coat the underside, backside and crevasses of the target, creating an “electrostatic wraparound.” In comparison, a 250 micron droplet simply runs off a target and is largely wasted.

Additionally there is the second half of Coulomb’s Law, that “like” charges repel. Since all of the coating droplets leaving the nozzle have the same charge, they cannot coalesce into large droplets, which again fall off the target. At the same time, the swirling droplets are not attracted to areas already coated and continue to seek out uncovered surface areas until there is uniform coverage (disposition) across the entire target. This results in a consistent, uniform coating, no drips, no runs and no uncoated areas.

What Matters Most
Microscopic organisms are usually hidden in deep cracks and crevasses inside or on the undersides of surface areas, and continue to survive if coverage is spotty. The extraordinary bonding of the coating to the target and the complete, uniform coverage achieved are distinct advantages of Microbecide® electrostatic sprayers. Experience is showing it is not just what is applied but how a coating is applied that matters most.

There has been researches mentioned that nowadays, even the air inside our buildings is worse that the air outside. This is mainly due to the finishes that we have using on our walls and ceilings (eg, paints and glues used on wall papers), floors (eg, materials used on our carpets), open spaces (eg, use of fragrances), washing materials (fragrances detergents) and etc. All the mentioned materials emits VOCs. Most of these VOCs contains harmful gasses that is dangerous to human Heath over a long time.
These danger can’t be seen and felt. The only way we can detect is either by smelling or using VOC testers.

Besides VOCs, even other micro-organic matters like bacteria, virus, molds/fungus and other allergens that we can’t see will harm our health over time. How can we know whether or not our home of offices or even our cars are filled with all these harmful microbes? They cannot be seen and felt as well. Again, there are numerous swap test equipments and expertise our there who is able to detect them.

So, what do we do after detection of such harmful matters that we have been living with? We take actions by trying to eliminate them. There are a lot of products that have the ability to minimize such contaminants, but does anyone really know what to use? Do they depend on a physical product like an air purifier? After determining that, do they go for the brands and then comparing prices? When they purchase these products to counter the IAQ problems, do they even check the air quality and cleanness of their surfaces once a while to make sure what they have purchased is useful? If they don’t, what makes them trust the products they are using? What different does that make to using nanoyo?

Nanoyo is a form of liquid which contains nano sized tio2. This liquid is applied onto all surfaces in the interiors of a building. This includes all ceilings, walls, floors and even all the furnitures and fittings within a building. When all these mentioned surfaces are applied with nanoyo, when there is like at presence, the treated surfaces will begin to have an ability to decompose anything that is organic upon contact. Therefore, it is able to oxidize VOCs, molds, odor, bacteria and viruses through a process call photocatalyst reaction.
The purpose of covering all the surfaces in the environment is to make use of every treated surfaces to work against all these harmful microbes. Nano tio2, when applied, can last a long time. It’s lifespan can be as long as 2 to 3 years without any maintenance like plugging it into your power supplies or even changing filters like air purifiers. The invisible coat, when applied onto surfaces, will never change the finishing of the surfaces.

So now, we have another option to consider when we are looking for something to solve our IAQ problem. Nanoyo has been in Malaysia for more than 7 years, applied to many premises such as hospitals, hotels, offices, residentials, karaokes, f&b outlets and etc, helping to solved different problems faced by the patrons here.

Arc Flash Applied External Structures of Malaysian Buildings with nanoYo

Year 2010 was a very meaningful year for Arc Flash Corporation (M) Sdn Bhd. In this year, we made it to history where we applied our Malaysia’s first Platinum Status Green Building for the control of indoor air quality, and we were also awarded 2 projects for external building application of our nano tio2 namely, the JPA Building at Putrajaya and the BMW HQ Building at THE QUIL, Cyberjaya.

This time around we would like to emphasize the other beauty of our nano tio2 effect of SELF CLEANING for external wall structures. Apart from being able to break organic matters that are harmful in the indoor sectors, our nano tio2 also breaks the oil surfaces that is trying to form on to external structures, not allowing dirt to be collected on these surfaces, even dusts only manage to sit loosely onto the treated surfaces because without the oily film, there is no bonding between the dusts and the surfaces and also, fungus/mold and other microbes could not grow on these surfaces too. When rain falls, all these dirts and dusts will eventually be washed away easily and hence the savings of cleaning and repainting jobs over a few years time.

Here are some pictures of the JPA/JKR project we did at C1 and C2 sector of the main building at putrajaya.

Application of nano tio2 by our Partner, A-Solution Enterprise






The process did not end with just the application. How do we proof that our nano tio2 treated surfaces are different from others?


We test it out in comparison with another site that has not been treated with our nano tio2 application.
Here, what we did was that we use an ATP Tester to read the microbe counts in 2 different sectors. 1 sector has been treated with our nano tio2 in comparison with 1 sector that has not been treated with the product, by random. We did this test not immediately after the application. The test may seemed to be bias if we do it right after the application. This is because, surely the surface will be cleaned right after the application, but for how long? Therefore, we did the ATP Swap test 14 days after the application. As you can see, the surface treated with our nano tio2 only contains 59 microbes as compared with a non treated surface that has 1000+ microbes. This clearly proves the application has long lasting effects, and not just some kind of chemical being used to kill the microbes on the surfaces temporarily.
The ATP TESTER is being used on food processing lines to check the cleanliness of their food processing lines. The readings of below 150 is very good, and 300 and above is considered failed. From this test, you can see that our nano tio2 treated surface has way passed the food processing tests and its even much cleaner. Do bare in mind that this is the external walls of the building where microbes such as molds can easily grow and start spreading their growth in seconds, but we waited for 14 days before we perform this test.

The other external project that we would like to highlight is the BMW application project at THE QUIL, Cyberjaya.








We did not did any ATP SWAP tests here but we believe that our customer’s satisfactory and testimonial marks a thousand words of what we have to say.

Here is a testimonial presented by the building owner which clearly states their satisfactory on our job done.


These are just 2 of the projects that has applied Arc Flash Corporation’s nano tio2 on their external buildings. We believe, if we manage to switch the mentalities of building owners, more of such projects will fall onto the application of such a great technology.

We hope that this blog not only have clearly explained to you what nano tio2 can do for external buildings, but also the multi benefits that this technology can give in just one product for both improving indoor air pollutants and also the self cleaning aspect for the external structures which will definitely lead to a very green building and great savings on building maintenance in the future.
