TiO2 Photocatalytic Oxidation Technology

The most consistent particle size of 2-3nm - making it the smallest and most active nano-TiO2 PCO solution currently available on the market.

Mostly all particles are above 10nm in size

Molecular particle sized TiO2 making it very active upon light activation...Our TiO2 particle size is in between molecular and crystal size.

Crystallised sized particle does not have as much oxidisation activity

Activates with a wide wavelength of between 230~450

Very narrow wavelengths and some require UV light for activation

Does not contain binders - nor require a pre-application primer

Mixing binders with TiO2 to have adhesion strength or the pre-application of any required primers will result in a thick coatings due to binder additives or primer applications

Almost every single one of our TiO2 PCO particles are active after application

Only surface TiO2 particles work but they will also oxidise the binder giving off a smell. While the hidden particles inside the binder have no activity!

Single application process - saving manpower costs

Some PCO coatings require double application - requiring a primer as a first coat.

Can be applied to most substrates with minimal preparation work

Besides pre-cleaning, there are many application limitations.

Good transparency on gloss surface and glass substrates

Blurred out gloss surface and glass substrates.

No change in substrate texture after application

Due to thicker coating, substrate texture may be affected.

Applied with electrostatic sprayer or our own X1 specialist HVLP sprayer for best coverage and lower wastage

Cannot use static application technology as the TiO2 mixture will cause equipment “choke up”

Our Solas Shield TiO2 PCO liquid can be stored in room light and at temperatures up to 30 degree C

Need to be stored in the dark or using opaque containers and stored in a cool temperature.

Another filtration system with a negatively charged surface, used to attract the particles. Compared to the HEPA systems, it is more effective in capturing particles smaller than a micron and in eliminating smoke in the air. Low levels of Ozone can be produced during this process - which is has the ability to neutralise the majority of mould, bacteria and fungi that come into contact with the filter.

Advantages                                                                                              Disadvantages

Absence of chemical residue                                                                        Very low efficiency

The HEPA (High Efficiency Particle Arresting) filter is one of the the best known method for air purification. Depending on the size of the filter mesh and area, it is able to clean up to 99.99% of particulate matter in the air with the correct ventilation. This filter system is not able to capture particles smaller than 0.3 microns. Neither is it effective in treating mould, bacteria, and fungi, however it can become a fertile ground for their growth.

Commonly used for disinfection, this technology is effective in sterilisation of air and surfaces which come into contact with UV light. It has also been shown that UV radiation is able to inactivate bacteria and viruses and stops them from reproducing.

This system also uses a negatively charged surface to produce and excrete large amounts of negative ions, allowing the suspended particles to settle on

walls, floors and other surfaces. Most Ionisers are effective in removing dust and particles present in indoor environments. Exposure to high levels of ionisation for excessive periods of time is now considered a health hazard

Based on the reaction of oxidation produced by the a photocatalyst, photocatalysis has proven to be very effective in destroying mould, bacteria, fungi, dust mites and odours. In the presence of air moisture, it produces hydroxyl radicals and superoxide ions, which are extremely effective against bacteria, fungi Particulate Matter (10 & 2.5) NOx and VOCs (Volatile Organic Compounds).

This technology is based on the use of Visible & UV Light and which also includes the use of a variety of combinations of lamps for low light areas.

Ozone is a very powerful antioxidant that neutralises odours, mould and bacteria. It should be noted that some air purifiers on the market still exceed the maximum Ozone concentration (50 ppb) guidelines laid down by the WHO,  increasing the risk of exposure to Ozone. Furthermore, when it is used under real conditions, the maximum concentration of Ozone depends on the actual physical size of the treated area and its level of supplied ventilation.
