Today we are under attack by a microscopic army. These microbes arrive in the
form of bacteria, viruses, mold, mildew, fungi, algae, and other organisms.
Once established, these harmful microbes may cause foul musty odors,
discoloration, property damage, allergies and disease.

Many of these microbes have mutated or adapted to the poisons being used to
control them. Chemicals must become more targeted and stronger. These harmful
microbes are being called "SUPER BUGS".

While other antimicrobials rely on poisons, toxic chemicals or heavy metal ions.
Mold Buster Z 7000 utilizes a patented molecular nano technology that destroys
microbes mechanically, without creating "superbugs". NO POISONS!
Mold Buster Z 7000 will safely and effectively reduce disease and odor-causing
microbes by up to 99.99% and inhibit their return for months and years at a time
from a single application, providing our customers the ultimate in cleaner, safer
living.

For our MOLD BUSTER Z 7000 or WKM Self Clean TX-85/TX-220 to perform as
designed, we must first make sure that the existing surface is clean and mold free.
1. The presence of mold is usually detected by either a “wet wool” smell or a visible
sign of dark spots.
2. A “mold spot” is a mass of mold cells that have formed a colony. Under a
microscope, they appear as a central cell with many ‘shoots’ that can extend up to a
meter from the nucleus.
3. These shoots (called ‘hyphae’) find moisture and bring it back to the main cell.
Nutrients from the moisture feed the mold and any unwanted matter is expelled as
a gas (a process called ‘aerosolising’). These gases produce the “damp wool”
smells we associate with mold and some are actually ‘mycotoxins’. These cause
allergic reactions, asthma, headaches and are very dangerous to your health.
4. Because of the possible presence of mycotoxins, we should treat all mold as
potentially dangerous and for this reason we recommend that appropriate Personal
Protection Equipment such as a mask and eye protection.
5. In order to prevent mold from surviving, we need to kill its ‘main cell’. For this
reason, we apply Mold Kill V 5000 that penetrates the ‘hyphae’ (the shoots) and
travels back to the main cell. The composition of this mixture is very important as it
penetrates the hyphae via osmotic pressure. This product is formulated to provide
the necessary reaction to kill the mold at its source. Destroying the roots.
6. After this process we apply our Mold Buster Z 7000 or WKM Self Clean TX-
85/TX-22 which is formulated to prevent new mold, germs, bacteria's, and virises
from growing for years.
7. Bleach does not kill mold. Rather, it works in the same manner as when applied
to hair, where it removes the color pigments but doesn’t kill the hair. Bleach used on
mold removes the color pigment but does not kill the mold itself (it just reduces
visibility to the naked eye) and the mold will return. Therefore, bleach should not be
used in this process.

What is Nano Technology ?
Nanotechnology, the revolutionary science and art of manipulating matter at the
atomic or molecular scale. Nanotechnology is not just about the size of very small
things. More important, it is about structure and the ability to work. Research in
areas related to nanomaterial is needed to develop manufacturing techniques, in
particular, is a synergy of top-down with bottom-up processes.

When a matter is as small as 1 to 100 nanometers, many of its features will easily
change and form into many different unique conditions both different from macromatters
and single atom due to the quanta effect, regional confinement of matter,
and huge surface or interface effects. The final objective of nanometer technology
is to produce products of special functions with new physical and chemical features
by making atoms, molecules and matters presenting their features directly in the
length of a nanometer: t he strength of ten times of iron could be very light, all
information in a library could be stored in a chip the size as a piece of square sugar,
and tumors the sizes of only several cells can be detected.

The US Business Weekly listed nanometer technology as one of the three key
areas in the 21st century . From 1999, the US government decided to put the
research in nanometer technology into one of the 11 key areas in the first ten years
of the new century. In February 2000, US president Bill Clinton announced that the
US Federal Government would invest 495 million dollars to set up a work group and
put forth a research report on the promotion, saying that it will lead to the next
industrial revolution as a top priority.

Titanium Dioxide's photocatalytic characteristic is greatly enhanced due to the
advent of nanotechnology. At nano-scale, not only the surface area of titanium
dioxide particle increases dramatically but also it exhibits other effects on optical
properties and size quantization. An increased rate in photocatalytic reaction is
observed as the redox potential increase as the size decreases. Energy from any
ambient light source can be used effectively as the energy source of photocatalysis
instead of UV light.

What is a Photocatalyst ?

A promising approach for remediating air quality contaminants is to employ
photocatalyst that oxidize these compounds. By definition, photocatalyst is a
catalyst that accelerates photoreaction.

When photocatalyst is exposed to light in the presence of water vapor, two
highly reactive substances are formed: hydroxyl radicals [OH] and a superoxide
anion [O2
-1]. It allows the oxidation of airborne VOCs and toxic organic matter
into carbon dioxide and water at room temperature with UV or near-UV light
source. It does not need a special energy and use only clean energy in
ordinary life.

Specific titanium dioxide has strong photo catalyst reaction. It has strong
oxidation and decomposition strength.
Photocatalyst has the following advantages over any current air purification
technologies:
• Real destruction of pollutant rather than a simple transfer on a substrate
• Degradation of pollutant at ambient temperature and pressure
• Build with easily available materials and by mean of well-known
techniques
• Economical, cheap and low energy consumption
• Adapted for a large range of pollutant (VOC, bacteria, mold)

What is Titanium Dioxide ?

Titanium dioxide, also known as titania, is the naturally occurring oxide of titanium,
chemical formula TiO2. Approved by the food testing laboratory of the United
States Food and Drug Administration (FDA), Titanium Dioxide is considered a safe
substance and harmless to human. It is commonly used in paint, printing ink,
plastics, paper, synthetic fibers, rubber, condensers, painting colors and crayons,
ceramics, electronic components along with food and cosmetics. Many studies
have been published on the use of titanium dioxide as a photocatalyst for the
decomposition of organic compounds. After illuminated by light, titanium dioxide
produces hydroxyl radicals, which react with the organic matters in the air to form
non-toxic inorganic matters.

Titanium Dioxide molecules contain electrons that are confined to relatively narrow
energy bands. The band of highest energy that contains electrons is the valence
band, while the band lying above the valence band, i.e. the conduction band, has
very few electrons. The difference in energies between the highest energy of the
valence band and the lowest energy of the conduction band is termed the band
gap energy. When a semiconductor absorbs a photon of energy equal to or greater
than its band gap, an electron may be promoted

from the valence band to the conduction band leaving behind an electron vacancy
or “hole” in the valence band. If charge separation is maintained, the electron and
the hole may migrate to the catalyst surface where they participate in redox
reaction with sorbed species

How they work together for Deodorizing, VOC and Odor Remediation,
Sterilizing, Anti-Bacterial and Mold Prevention ?

On the deodorizing application, the hydroxyl radicals accelerate the breakdown of
any Volatile Organic Compounds or VOCs by destroying the molecular bonds. This
will help combine the organic gases to form a single molecule thatis not harmful to
humans thus enhance the air cleaning efficiency.

Some of the examples of odor molecules are: Tobacco odor, formaldehyde,
nitrogen dioxide, urine and fecal odor, gasoline, and many other hydro carbon
molecules in the atmosphere. Titanium dioxide has strong oxidation affects to
single-celled organism that includes all bacteria and fungus. The very strong
oxidizing power of Titanium Dioxide can destroy bacteria's cell membrane, causing
leakage of the cytoplasm, which inhibits bacteria’s activity and ultimately results in
the death and decomposition of bacteria. Generally speaking, disinfections by
titanium oxide is three times stronger than chlorination, and 1.5 times stronger than
ozonation.

Super Hydrophilic Property
Self-Cleaning, Anti-Soiling and Anti-Fogging

The hydrophilic nature of titanium dioxide, coupled with the gravity, will enable the
dust particles to be swept away following the water stream, thus making the
product self-cleaning.

When the surface of photocatalytic film is exposed to light, the contact angle of the
phtocatalyst surface with water is reduced gradually. After enough exposure to
light, the surface reaches super-hydrophilicity. In other words, it does not repel
water at all, so water cannot exist in the shape of a drop, but spreads flatly on the
surface of the substrate. And the water took the form of a highly uniform thin film,
which behaves optically like a clear sheet of glass.

Most of the exterior walls of buildings become soiled from automotive exhaust
fumes, which contain oily components. When the original building materials are
coated with a photocatalyst, the dirt on the walls will wash away with rainfall,
keeping the building exterior clean at all times.

Air Purification Technology Comparison

HEPA (High Efficiency Particle Arresting) Filter
Most widely known method for purifying air. Depending on the filter size, it can
clean up to 99.99% of particulate in the air with proper ventilation. They are not
effective on treating mold, mildew, bacteria, and other fungi.
Electrostatic Filtration
Another filtration system with a negatively charged surface is used to attract
particulate. In comparison to most HEPA systems it is more effective in trapping
smaller micron particulate and effective in clearing smoke from the air. Low levels of
ozone may be produced which can neutralize most mold, mildew, bacteria, and
other fungi that comes in contact with the filter.
Ionization
Also uses a negatively charged surface to produce and expels an abundance of
negative ions and cause suspended particles to cling to walls, floors, and other
surfaces . Most ionizers are effective in settling dust and particulate out of our
breathing space.
Ozone
Ozone is a very powerful oxidizer that will neutralize odors, mold, mildew, bacteria,
and other fungi. This technology is commonly used in flood and fire restoration.
Ozone is found to be effective because it works on the problem at the source and
air does not have to be pulled through the unit for treatment.
UV Germicidal Lamps
Commonly used for disinfecting purposes. This technology is effective in sterilizing
air and surfaces that come in contact with the UV light. UV has been proven in both
air and water applications to inactivate bacteria and viruses to prevent them from
reproducing.
Photocatalysis
Using light to react with a catalyst resulting in oxidation. This is found to be effective
in destroying mold, mildew, bacteria, other fungi, dust mites, and many odors. This
technology is produced with an Ozone/UV lamp set in a variety of combinations.
When this type of photocatalysis is combined with the natural humidity in indoor air
it creates hydroxyl radicals and super oxide ions that are effective in combating
bacteria, fungi and VOC. This method is also a pro-active approach that goes to the
source for treatment.
