Teflon®
Coating
Because
of our experience in applying Teflon® coatings,
our skilled staff, and modern equipment, Crest has been
a DuPont Licensed Industrial Applicator
for more than 30 years. This is a source of pride for
us, and a source of confidence for our customers. The
variety of Teflon® industrial coatings is extensive.
For
any particular use, there may be several Teflon®
coatings that will perform well. Drawing on the experience
of a Licensed Industrial Applicator ensures the best
Teflon® coating for a given application, whether
it be PTFE®,
FEP®, PFA®, ETFE®, Teflon-S®,
or others. Crest’s
engineering and coating expertise is recognized nationwide.
Customers from all parts of America routinely send components
to us for coating.
Outstanding
Properties of Teflon®
 |
NONSTICK
Very few solid substances will permanently adhere to a Teflon® coated finish.
Although tacky materials may show some adhesion, almost all substances release
easily. |
 |
LOW
COEFFICIENT OF FRICTION
The
coefficient of friction of Teflon® is generally
in the range of 0.05 to 0.20, depending on the
load, sliding speed, and particular Teflon® coating
used. |
 |
NONWETTING
Since surfaces coated with Teflon® are both oleophobic and hydrophobic, they
are not readily wetted. Cleanup is easier and more thorough — in many cases,
surfaces are self-cleaning. |
 |
HEAT
RESISTANCE
Teflon® industrial coatings can operate continuously at temperatures up to
260°C/500°F and can be used for intermittent service up to 316°C/600°F
with adequate ventilation. |
 |
UNIQUE
ELECTRICAL PROPERTIES
Over a wide range of frequencies, Teflon® has high dielectric strength, low
dissipation factor, and very high surface resistivity. By special techniques,
it can even be made electroconductive enough to be used as an anti-static coating. |
 |
CRYOGENIC
STABILITY
Many Teflon® industrial coatings withstand severe temperature extremes without
loss of physical properties. Teflon® industrial coatings may used at temperatures
as low as -270°C/-454°F. |
 |
CHEMICAL
RESISTANCE
Teflon® is
normally unaffected by chemical environments. The
only chemicals known to affect all Teflon® industrial
coatings are molten alkali metals and highly reactive
fluorinating agents. |
