Why
do the ingredients make THERMO-SHIELD Coatings THE SUPERIOR product in the
World’s coatings market? What is so
different from them compared to paints and other roof coatings? These are questions we are frequently being
asked.
It
took GENERAL INDUSTRIES CORP. of Colorado Springs, Colorado, 7 years of
preparation, testing, and changes to develop their “PERFECT” roof coating, a
product designed with the goal “TO CURE ALL ROOFING PROBLEMS”.
GENERAL
INDUSTRIES was not working alone:
A. ROHM and HAAS, the resin supplier worked closely in
developing and providing the very special resins needed to accomplish this
task.
B. 3-M worked with GENERAL INDUSTRIES to determine what the ideal
ceramic particles were to be most efficient for insulation of buildings and
to best reflect solar radiant heat.
These ceramics were an off-spin of the space shuttle technology. They are similar in that they are hollow
ceramic micro-spheres having tremendous ability to reflect and dissipate heat
and act as nonconductors of heat. The
ceramics we used differ because the needs of a building are different from the
requirements of a space shuttle. On
buildings we concentrate on solar heat, where the space shuttle is concerned
mainly with heat from friction. Also,
it is not practical to put ceramic tiles all over a building, so THERMO-SHIELD
was developed incorporating the bubbles in an easy to apply elastomeric
coating. Different methods, but the
same end result, a great insulative coating.
C. Much of the SPACE SHUTTLE technology was developed in the
Colorado Springs Area. Some of their
engineers were available for consultation to help determine how this space age
information could be incorporated into building coatings to make homes and
business more energy efficient.
HOW
DO THERMO-SHIELD COATINGS DIFFER FROM COMMON PRODUCTS?
All
of the ingredients are synthetic. Most
other coatings use organic materials (Natural ingredients) that are broken down
by nature: Thermal Shock, Extreme Heat or Cold, Chemicals, Ultra Violet Light,
Ozone Decay, Blistering, Weather such as Wind, Rain, Snow, Hail, Sand
Abrasion. Other coatings get hard,
crack, peal, and decay and turn chalky or simply decompose. THERMO-SHIELD’S unique ingredients overcome
all these problems. The three basic
components are RESINS, the “glue”, FILLERS, the “body”, and PIGMENTS, the
“coloring”.
RESINS: We use Acrylic Elastomeric resins, which add
these benefits:
A. They remain elastic - move with any changes in the building,
covering cracks and preventing new cracks from appearing. They stay elastic when very cold (Lab tests
show the coatings will not crack at -37° C).
B. They cover the entire surface with a seamless membrane
preventing water or air penetration.
When applied at the recommended thickness, the roof coating will stand
up to prolonged ponding of water, a property we have not seen in other
elastomeric coatings.
C. They are very resistant to nature’s breakdown
processes. Laboratory accelerated
weathering tests indicate that after long exposure, our coatings actually get
tougher and maintain their elasticity (Other coatings deteriorate in these
tests).
D. When you stretch a THERMO-SHIELD coating, it will draw back
into its original shape. When a
hailstone hits it, it will cause dents, but the coating will immediately spring
back. The coatings are very resistant
to hail, protecting the substrata from damage.
E. The resins are made up of very complex polymers that have
the ability to hold onto huge amounts of solid particles and still have
great adhesion (Normal resins loose much of their adhesion as solids are
added). We add huge amounts of our
ceramic micro-spheres, which want to float to the surface, but are held in
suspension by the polymers. Some of our
competitors claim to have similar ceramic benefits, but use solid ceramic beads
instead of bubbles because they cannot keep the bubbles in suspension. The solid particles do not have the
insulative benefit of the micro-spheres.
F. The resins give THERMO-SHIELD its UV protection; they get
tougher and more elastic with UV exposure, insuring long life.
G. The Roof Coat resin has a very special property that makes
our roof coating unique from any other type of roofing product we have
seen. It has “VARIABLE
PERMEABILITY”. When conditions are wet,
the polymers swell up becoming completely watertight. When conditions are dry the pores in the Roof Coat open up and
trapped moisture can breath out. This
is of great importance. Other roofing
products are watertight all the time.
Moisture will work up through the substrata and become trapped under the
waterproof material. When this moisture
heats up it turns water to vapor, expanding many times, causing blistering and
destroying adhesion, or it freezes which also breaks down the adhesion, leading
to roof failure.
FILLERS: Most coatings use cheap fillers to keep the
cost of their product down. Fillers
like China Clay are common, organic products that, because they are developed
by nature, are quite readily broken down by nature. Scotchman uses ceramic micro-spheres; very similar to the
ceramics used in the Space Shuttles, which are close to indestructible by the
conditions faced each day by buildings.
A. Ceramic micro-spheres are about 50% by volume in
THERMO-SHIELD coatings.
B. The micro-spheres help our coatings reflect about 83% of the
Solar Light. (They reflect about 85% of
the infrared or “Hot” end of the light spectrum). They stop most radiant heat transfer before it ever becomes a
problem.
C. Ceramic is one of the best non-conductors of heat; they
reduce heat transfer by conduction.
These micro-spheres are also hollow and vacuumed inside - the best
insulator.
D. With ceramics you have to add a new term to your insulation
vocabulary “DISSIPATION”. Other types
of insulation just slow down the transfer of heat. Ceramics can “dissipate” heat transferring it back into the
atmosphere - the heat never gets into the building to become a problem (or in
the case of THERMO-SHIELD Interior coatings, the heat is not lost out of the
building). A cube of ceramic material
can be heated to over 1100O C and be safely picked up with bare
fingers only seconds later while the cube is still glowing red-hot in the
center. Ceramics make the heat
dissipate quickly from the surface.
Many people think a thin coat of THERMO-SHIELD cannot provide
insulation. THEY ARE VERY WRONG!
E. Because of the ceramics, our coatings are more resistant to
dirt accumulation than other elastomerics.
Dirt will wash off easily with a garden hose wash down.
F. The ceramic micro-spheres themselves are fireproof and can
dissipate great amounts of heat. As a
result, THERMO-SHIELD coatings have a good fire resistance. In the Japanese flame tests, our coating had
Zero flame retention.
PIGMENT: THERMO-SHIELD coatings make use of Titanium
dioxide and Aluminum -trihydrate as our white pigments. These are very stable substances that are
very resistant to natural breakdown and add to the reflectivity and to the long
life and fire resistance. Thermo-Shield
is rated Fire Resistance Class A. Many
competitive coatings use cheap pigments that easily break down, resulting in
chalkiness, short life and early fading.
In
short there is no weak link in the THERMO-SHIELD FORMULA. The ingredients combined form coatings that
are:
A. Environmentally safe - water based both liquid form and
cured coatings are free of toxic materials.
Lab tests show there are no harmful effects from their application.
B. Resistant to fading - Japanese tests showed Thermo-Shield
had less fading than any other paint tested for the Japanese market.
C. Long life - applications more than 14 years old are still
holding up well with no signs of cracking, hardening or peeling. Roofs are still watertight even where they
have been exposed to long-term water ponding.
What problems have appeared have almost all been applicator errors and
those have been repaired easily by additional coating on the problem area? The first Exterior wall jobs are still
bright and fresh looking with no noticeable fading.
D. THERMO-SHIELD coatings are very resistant to chemicals. The Calcoast tests show the finished
products were unharmed by some very harsh chemicals, including battery acid and
salt-water solutions.
These
are the basic ingredients and the reasons they make THERMO-SHIELD like no other
protective coating available. Combined
together with a few additives, such as thickeners, fungicides and others, they
provide the end user with affordable, “PROBLEM SOLVING”, Space Age Protection.
