It has long
been known that fluorinated polymers have many properties that are
superior to their hydrocarbon counterparts. Among these properties
are the ability to better resist heat, light and chemical attack
- all things which cause protective coatings to fail, In addition,
Fluoropolymers are known for very low surface energy, a quality
which imparts to the polymers improved water, oil and soil resistance.
The disadvantage of Fluoropolymers has been in trying to apply them
to a surface as a coating. Fluoropolymers were both expensive and
difficult to apply, generally requiring high temperatures to cure.
This was true until SP created its set of fluorinated Coatings.
The new materials created by SP, make it convenient and practical
to apply a fluorinated coating using conventional painting equipment,
any of the series of fluorinated coatings can be applied and cured
under ambient conditions. These coatings have excellent adhesion
to most epoxy, alcyd and polyurethane primers. Our fluorinated coatings
even adhere to themselves (even after aging), a quality that allows
for the easy repair of damage to a coating. The SP Fluoropolymer
coatings have permeability which is an order of magnitude lower
than conventional coatings. This prevents moisture and oxygen from
reaching the surface of the substrate. Corrosion, like combustion
requires the presence of several essential ingredients in order
to proceed. The elimination of one or more of these ingredients
means that corrosion cannot occur. The SP Fluoropolymers have proven
to be low enough in permeability to prevent sufficient oxygen and
water from reaching the surface for corrosion to take place.
One of the
first applications of Fluoropolymers was in the environmental test
chamber, (the cloud physics chamber) operated for the EPA at Calspan
Corporation. Originally coated in 1973, the test chamber is used
to study pollutants from various sources at high altitudes, where
different chemicals can react together under intense UV radiation.
Calspan needed a coating that would be easy to clean and would not
react with the experiments being conducted within. Teflon and Fluoropolymer
were the only two materials which qualified. Calspan coated the
entire chamber from floor to ceiling, including the light fixtures
and the energy Lamp bulbs (used to activate the experiments) with
fluoropolymer. For more than a decade coating has been subjected
to a wide range of pollutants including auto and diesel exhaust,
emissions from power plants, chemical companies, volcanos, trees,
sewer and water treatment facilities, and even chemical weapons.
The coating is still in excellent condition and the chamber is still
in use.
The SP Series
of Fluoropolymer Coatings are:
Weather Resistant (shows no weathering characteristics even after
prolonged exposure Chemical Resistant (does not react with most
chemicals)
Resistant to Soiling (dirt does not stick)
UV Light Stable (immune even to high doses of UV)
Corrosion Barrier (does not permit moisture or oxygen to reach the
substrate)
Hydrophobic Surface (water cannot wet the surface)
Oleophobic Surface (oil cannot adhere to the surface)
Organo-phobic Surface (surface contains no nutrients upon which
organic material may feed) Low Surface Energy- Non-Stick Surface
Low refractive index for optical applications
Immune to electrical breakdown, Dielectric
