house can't clean itself yet, but certain parts
of your house can clean themselves and clean the
air, too! Nanotechnology is beginning to yield
commercial products which directly improve people's
lives. One of the new "nano products" is photocatalytic
coatings which comprise nanocrystals that result
in self-cleaning activity when exposed to light.
April 26, 2005 -- Green Millennium Inc., based
in Los Angeles, California, has appointed Novapure
Systems Inc., of Calgary, Alberta, Canada, Master
Distributor for the Green Millennium line of new
photocatalytic coatings for the Canadian market.
Photocatalytic coating solutions are a direct result
of nanotechnology research and are very effective
for self-cleaning and hygienic applications. States
George Tseng, of Green Millennium, “Our coatings
can be applied on most surfaces and will impart self-cleaning
properties to any surface. Additionally, the surface
coating will purify the air by oxidizing airborne
fumes and odors. This product is truly an early benefit
of nanotechnology and one of the first commercial
products derived from nanotechnology research”
“The coatings, known as “photocatalytic coatings” are usually applied like a
spray paint, are not toxic and are very cost-effective. The photocatalytic coating
solutions have been used for years in Japan, where they were originally developed
to combat air pollution, infectious microbes and soiling of exterior surfaces.
When applied, the treated surface oxidizes contaminants in the presence of light.
The result is a self-cleaning surface which will degrade any organic substances
such as grease, oil, soot or microbes. The result is that the surface remains
clean and attractive, instead of becoming soiled or faded”, adds Tseng.
The coating is used in Japanese hospitals to combat disease transmission (e.g.,
MRSA, Staphylococcus aureus, C. diff.) and reduce sickness in day care facilities
and schools, as well as offices and homes. Many people with respiratory illnesses
(e.g., asthma, allergies) can benefit. As well, building exteriors, signage
and awnings are treated to retain their beauty and eliminate costly cleaning.
A side benefit is that sun damage (e.g., discoloration) is lessened. Treated
surfaces will not discolor or age as quickly as untreated surfaces. This will
add years to the life of awnings, signage and paint and save millions of dollars
in replacement costs.
The products are also used for odor control. On treated surfaces the nanoparticles
in the coating continuously degrade odors and fumes (volatile organic compounds)
in the presence of light. The removal of chemical odors makes for a more pleasant
environment due to improved indoor air quality, and it can also provide relief
for people with chemical sensitivities.
“We are proud to be working with the leading supplier of photocatalytic coatings”,
says John Pink, President of Novapure. “The Green Millennium product is a superior
solution. Once people fully appreciate the benefits of these coatings, there
will be innumerable uses for the technology. It really is exciting to be involved
with technology that is not only effective, but one that is safe and doesn't
harm the environment.” To address the expected demand, the product will be marketed
through trained distributors and applicators. The photocatalytic coatings industry,
already a multi-billion dollar market in Japan and the Far East, is only in its
infancy in North America.
