Superior Performance of a New Inorganic
Photocatalytic Coating Composition.

Industrial and exhaust exhalations, organic contaminants from plastics and many other substances
around us are threat to human health and they lower the quality of our environment. According to
the WTO, more than 15% of chronic diseases are caused by bad air quality. A high percentage of
allergies, contagious infections, bad odors or darkening of facades are a few examples of the
impacts of contaminated air. Man is forced to protect himself and one exciting possibility is the use
of photocatalytic coatings.
Photocatalytic paints based on TiO2 are commonly seen on the market now, however; their
declared photocatalytic activity may vary. Their photocatalytic efficiency is often merely symbolic
due to the binders blocking the TiO2 surface in the paint composition.
This is mainly true for all silicon and silicate based binders which cover the TiO2 nanoparticles
almost completely eliminating the photocatalytic effect.
Advanced Materials-JTJ, found and patented a binder that does not block the photocatalytic
activity. In fact the binder is covered by the TiO2 nanoparticles allowing a direct contact of gas
with the TiO2 photoactive surface.
In contrast to the organics or inorganic silicone and silicate binders covering the TiO2 surface,
particles of the said binder are covered by nano-TiO2. The composition is created by a reaction of
inorganic agents in the presence of TiO2 nano particles.
As a result the photocatalytic activity of this product is orders of magnitude higher compared to
photocatalytic paints.
This brings a new value in use to these coatings, because they qualify as an air cleaning system.
Air cleaning, antimicrobial properties and field studies will be demonstrated.
ABSTRACT
MECHANISM – CONVERSION OF LIGHT ENERGY
INTO AN OXIDATION POTENTIAL ON THE
SURFACE OF TITANIUM DIOXIDE
ORGANICS
(SMOKE, MICROBES, VAPOUR, ETC) + AIR OXYGEN
TiO2 SURFACE +
+ LIGHT H2O + CO2
Eg ~ 3.2eV
HOW DOES IT WORK?
Regular paint
When smoke comes
into contact with
the photocatalytic
surface, it reacts
with the oxygen
(burns) creating
molecules of water,
CO2 and other
mineral
compounds. 6 months
Smoke and oxygen co-exists in the air without any problem.
Smoke creates musty deposits on a regular wall.

ADDITIONAL BENEFITS
ANTI-GRAFFITI
PERFECTLY SAFE
• The active compound in FN1® and FN2® is photoactive titanium
dioxide (TiO2), which is a common pigment We can find it just about
everywhere (paper, paints, plastics, whipped cream, bread). TiO2 does
not represent any health risk.
• The photocatalytic layer is pH neutral and non-irritating
• Ecologically friendly
Fish 250ml FN2/l – 96 hours – no obvious problems
Mustard seed – 40% faster growth
Skin Cells – Low phototoxicity
Maintenance – recommended - once a year 1 hour
