DURABILITY - means permanent,
not temporary, repairs
How many times have you come across clients who opted for
cheaper products at first but those products didn't work!
When it comes to durability and high-performance two things
count: ASTM (American Society Of Testing
Materials) and actual performance in the field.

On the ASTM front, many companies, knowingly
or unknowingly, publish "exaggerated" numbers.
This is unfortunate, because sometimes, these exaggerated
numbers are even higher than those published by THISTLEBOND.
Unsuspecting prospects who take them by their face value
end up going with the competition, only to realise that
they didn't perform well at all!

Case Points |
- 1. A competitive company who has been
around and who should know better, uses "aspirin
pill" size samples in a compressive test ASTM D-695.
These samples are illegal because the smallest size allowed
is 12.5mm diameter by 25.4mm height cylinder or 12.5mm
X 12.5mm X 25.4mm prism. These small "aspirin size"
specimens give higher compressive test numbers and this
company publishes them. Side-by-side tests show that THISTLEBOND
is superior, but this company insists upon publishing
those higher numbers.
- 2. A competitive company claims that
their products do not shrink. Whereas all commercial monomers
shrink during polymerisation. Some shrink more than others.
But they all shrink. It is the nature of the beast. This
shrinkage can be offset a great deal with proper formulation
by using the right fillers. Although this will reduce
shrinkage to negligibly small amount, it is still measurable
with sensitive electronic tools, and it must be reported.
- 3. Another "trick" some competitive
companies use is to employ a misleading test method: for
example use ASTM C-157, which is for measuring concrete
shrinkage, instead of ASTM D-2566, which is for measuring
plastics shrinkage. "C" is for concrete tests
and "D" is for plastics tests. Polymers are
generally classified under "D". If you use C-157,
you will measure "zero shrinkage" for all polymers,
because the measurements are taken after 7-day cure, since
the test is designed for concrete. But all commercial
polymers shrink within the first few hours of cure! There
is no more dimensional change left in the system after
a few days, let alone 7 days! THISTLEBOND
tests properly, according to ASTM, and publishes average
results, not just the top result.

As you can see from the above. "Higher
numbers" don't necessarily mean "better products".
Having made the point of "exaggeration" and "publishing
inflated test numbers" on the part of some competitive
companies this way, we can now safely say that THISTLEBOND
test numbers are still at the top! That is the first indication
of why THISTLEBOND is so superior to the
competition: HIGH PERFORMANCE and DURABILITY!
