How LumActiv Works

This coating uses photocatalytic titanium dioxide (TiO2) nanoparticles to absorb ultraviolet (UV) and visible light to drive the decomposition of water to hydroxyl radicals or organic and inorganic compounds to their oxidized forms (such as nitrous oxide (NOx) to nitrate salts). The hydroxyls produced can undergo further reactions with odors, organic and inorganic compounds, and pollution to eliminate harmful species in the air and produce water in a catalytic cycle.

In 1967, Ph.D. student Akira Fujishima working in a small lab at the University of Tokyo, discovered that the anatase form of titanium dioxide, a common food pigment, decomposes volatile organic compounds (VOCs) and other air pollutants when exposed to UV light. More than 49 years and over 3,000 academic studies later, scientists agree that global air pollution can be positively impacted by the widespread application of photocatalytic anatase titanium dioxide coatings.

In the presence of light, the compounds that our coating is capable of decomposing include nitrogen oxides (NOx), carbon monoxide (CO), formaldehyde, benzene, allergens, pathogens, odors and other volatile organic compounds (VOCs). These pollutants are converted into non-toxic compounds like carbon dioxide, water, and nitrates.

 

 

Our photocatalytic coating works by creating hydroxyl radicals and superoxide ions during photocatalysis – these ‘scrubbers’ break down harmful organic airborne pollutants such as VOCs, nitric oxides, carbon monoxide, and methane into harmless byproducts.

Additionally, thanks to advances in nanotechnology, this coating contains nano-scaled particles that allow for an increased surface area of reactive material when compared to larger-scale particles. As a result, the photocatalytic coating has a higher rate of photocatalytic activity and decomposes organic pollutants much more quickly than our competitors, as evidenced by the ISO testing results of the International Photocatalyst Standards Testing Centre.

Whether our customers are environmentally conscious and intent on decreasing the air pollution in urban environments, looking to create healthier indoor environments, or only interested in keeping their assets clean and reducing building maintenance costs, America Nanocoat’s photocatalytic coatings offer an innovative eco-friendly solution.

Visible Light Photocatalysis
Photocatalytic oxidation had once only been possible under the presence of UV light, and now with the chemistry America Nanocoat has to offer, it is now reactive into the visible light spectrum. The activation of this reaction in by visible light is possible through the doping of TiO2 with silver ions.

 

FAQs

Photo- meaning light and catalyst- being a component that speeds up a reaction without being consumed; therefore, a “photocatalyst” is a material that, in the presence of light, speeds up a chemical reaction without being consumed. The reaction that is being sped up with LumActiv is the production of hydroxyl radicals from UV light. This is a naturally occurring process that occurs in the atmosphere to help clean the planet. Hydroxyl radicals are known as the “atmosphere’s detergent” for their impressive cleaning power. Water is a co-catalyst in the reaction to clean the air.

LumActiv Glass: Glass surfaces such as windows, solar panels, automotive glass, architectural glass

LumActiv Indoor: Indoor surfaces exposed to mostly indoor light

LumActiv Multipurpose: Surfaces exposed to large amounts of UV light, outdoor applications

LumActiv Primer: Organic surfaces that LumActiv will be applied to, acting as an inorganic barrier. Plastic or other hard hydrophobic surfaces to increase adhesion.

Ensure a clean, dry surface before application. For glass and other hard surfaces a surface degreaser, such as our Glass Cleaner, can be used. If the glass is heavily soiled, a glass scraper may be necessary. If the surface is organic in nature and will be exposed to large amounts of UV exposure, LumActiv Primer should be applied prior to the final LumActiv product.

LumActiv Primer is used under two conditions, the first being on an organic surface to act as an inorganic barrier between the active LumActiv coating (Multipurpose or Indoor) and the substrate the coating is being applied to, such as an organic paint. The LumActiv Primer can also be used to increase adhesion and act as a binding agent between the surface and the coating.

3 to 12 hours are required for the film to fully dry. The dry time can be accelerated with heat so long as the temperature does not exceed 600C. Once the coating has fully dried, the coating will not dissolve in water.

The coating will fully cure in about 2 months. At this point, the coating will have achieved maximum hardness (2H-5H depending on the coating/substrate).

If there is an area of the coating that needs to be reworked, the coating should be removed immediately. Coating can be removed by wiping with water and a cloth.

All tools can be rinsed with water to remove any remaining coating solution.
