Frequently Asked Questions (FAQ)

CleanCoat™ (13)

  1. What factors influence the efficiency of CleanCoat™ coatings?

Light and airflow have a strong influence on the reaction of the TiO2 catalyst, as both provide elements needed for the reaction.

Regular lighting is effective, especially fluorescent lights, such as those found in many kitchens and offices. The equivalent of a 60W light bulb has been shown to be enough to start and continue the photocatalytic process.

However, direct sunlight, UV radiation, and black lights (UVA) create the most oxidants.

  2. How long does CleanCoat™ have to be exposed to light before it releases oxidants into the air to get rid of indoor air pollution?

This process begins immediately, but varies with the strength of the light striking the CleanCoat™ surface. Regular lighting will activate the process, especially fluorescent lights, such as those found in many kitchens and offices. However, it is direct sunlight, UV radiation and black lights (UVA) that create the largest amounts of oxidants.

  3. How does CleanCoat™ work as a "self-cleaning surface"?

In the presence of light, either from the sun, or artificial sources, the CleanCoat™ TiO2 [Titanium Dioxide] coating catalyses a reaction in ambient oxygen and water vapor, creating Hydroxyl radicals.

These hydroxyl radicals are highly reactive and they rapidly break down any organic compound exposed to them, including bacteria, viruses, mold, algae, mildew, organic particulates, VOCs [Volatile Organic Compounds], oils and dirt in general. These organic contaminants are continuously destroyed, and never have a chance to grow on or adhere to the treated surface. The decomposed compounds are shed directly, or easily washed off with water (including even rain), resulting in a self-cleaning effect.

  4. How does CleanCoat™ prevent and remove contamination from surfaces?

Airborne contaminants such as second-hand smoke, car exhaust, molds, viruses, bacteria, and other organic compounds cannot adhere to surfaces treated with the CleanCoat™ coating because they are oxidized by it. They are broken down and are discarded as harmless substances (carbon dioxide CO2 and water H2O).

  5. Why does CleanCoat™ have a sterilizing and antimicrobial effect?

The longtime standard for eliminating airborne microorganisms has been strong UVC radiation (over 20,000 μW of UVGI per second). UVC germicidal radiation eliminates microbes by destroying their DNA. However, some microorganisms, anthrax in particular, have very strong DNA coatings and can resist even 30,000 μW of UVGI.

  6. The CleanCoat™ coating works in a different way, as TiO2 decomposes and destroys the cell membrane, not the DNA.

Most microbes are single-celled organisms, so they die quickly when any part of them comes into contact with a treated surface. Accordingly, TiO2 even eliminates MRSA (Staphylococcus Aureus), a major cause of hospital infections. Japanese hospitals have demonstrated great antibacterial results with CleanCoat™ treatment. The CleanCoat™ coating has been proven to eliminate microbes that are immune to antibiotics.

Further, due to its oxidizing mechanism, it even decomposes toxins that are discharged when microbes die (Verotoxins, Enterotoxins), rendering them into harmless vapors.

  7. How is CleanCoat™ applied?

CleanCoat™ is best applied to hard surfaces using an electrostatic sprayer. It can be brushed or sprayed onto softer, or fabric surfaces. When applied to fabrics, spray the surface until it is completely moistened, then a brush (of any sort) should be used to work the solution into the fabric.

When applied to non-fabric surfaces (plastic, metal, glass, etc.) the initial coating will leave a fine milky residue. Allow the area to completely dry, then wait several hours and wipe the area with a damp cloth.

  8. How long does it take for CleanCoat™ to dry?

CleanCoat™ dries within minutes on solid surfaces, but takes a little longer to dry on fabrics. The time needed for this (evaporation time) will vary with temperature, air circulation, and humidity. CleanCoat™ takes 1-1½ hrs to harden fully, so heavy traffic on flooring is not advised immediately after coating.

  9. How long does it take for CleanCoat™ to settle and dry before I can enter the treated area?

Tests done at the the Danish "National Research Centre for the Working Environment" show that it takes a maximum of 3 hours, worst case, for all the CleanCoat™ particles to settle and dry.

Good ventilation and air circulation can shorten this period of time to about 2 hours.

During this time, only Anano Sphere trained and approved professionals may be in the area, and must use the stated Health and Safety materials.

10. Does CleanCoat™ smell after application?

No. Once applied, CleanCoat™ is invisible and odor free.

11. Does CleanCoat™ cause any fabric discoloration or any streaking effects on solid surfaces?

CleanCoat™ coatings can be applied to fabrics, curtains, carpets, woods, tiles, ceramics, glass, even metal and painted surfaces. If the surface is exposed to direct sunlight, it should not be applied to black or very dark colored surfaces, as the oxidation process can remove some pigments from the surface.

Indoor light is not strong enough to cause this oxidative reaction however.

When spraying any surface with the CleanCoat™ coating, it is always advisable to spray a small test area first, and then allow it to dry, to make sure the solution does not react with the surface.

12. How long after the application of CleanCoat™ does its properties remain active?

Anano Sphere certifies 1 year of Active Environmental Control if the correct cleaning procedures are followed. CleanCoat™ forms bonds that are semi-permanent, depending on the surface to which it is applied. Physically flexible materials, like carpets, mats and clothing, may undergo a physical peeling off as they are repeatedly reshaped over time.

Generally speaking, the CleanCoat™ coating has a service life of 1 year or so, depending on the wear and tear on the coated surface.

13. Does CleanCoat™ have a shelf life?

Yes. In optimal conditions, CleanCoat™ has a shelf life of 1 year. As CleanCoat™ is light reactive, it should be stored in a dark, cool environment.
