CHROME PHOSPHATE PRETREATMENT
AND PRIMER:
Amorphous
Chrome Phosphate Conversion
Coating: The chromium
phosphate conversion
coating provides the
ultimate surface protection
against corrosion and
is an excellent paint
anchor.
Strontium
Chromate Primer: The
strontium chromate primer
blocks the intrusion
of corrosive air borne
contaminants to the
substrate.
KYNAR
500:
Kynar
500 is a Fluoropolymer
Coating, wet ( solvent-based
)* system. The secret
of fluoropolymer's remarkable
properties lies in its
molecular structure;
the carbon/fluorine
bond ( one of the strongest
known to man ) is the
key to the coating's
unsurpassed thermal,
chemical and ultra violet
resistance. The final
coating for aluminum,
galvanized steel, or
aluminized steel is
a factory-applied, oven
baked finish based on
KYNAR 500R * resin (Polyvinylidene
fluoride). This finish
is a dispersion coating
based on KYNAR 500 resin
as formulated by Elf
Atochem North America,
Inc.'s KYNAR 500 licensees.
This finish is in strict
accordance with the
formulator's specification
and applied by an applicator
approved by the formulator.
This finish based on
KYNAR 500 shall meet
the performance criteria
of AAMA 2605.2 specification,
and certified by the
formulator as containing
KYNAR 500 resin as manufactured
by Elf Atochem North
America Inc.
Color
Coat: The secret of
Kynar 500's exceptional
weathering properties
lies in its molecular
structure. The carbon
/ fluorine bond is one
of the strongest molecular
bonds. The Kynar 500
resin in combination
with highly durable,
time tested pigments
is the key to the coatings
unsurpassed thermal,
chemical and ultraviolet
resistant properties.
KYNAR
XL:
Kynar
XL: The clear Polyvinyledine
fluoride (PVDF) top
coat protects the underlying
color pigments from
the elements that cause
chalking and fade. The
lubricity of the finish
also encourages abrasive
elements to skid off
rather than dig in,
and this non stick characteristic
also is extremely stain
and graffiti resistant.
ACRYLIC:
Acrylic
coatings add beauty
and durability to a
variety of residential,
institutional, and interior
components. They combine
good color permanence
with low maintenance
and are economical.
Acrylic coatings must
be factory applied by
spray and the aluminum
must be properly cleaned
and pretreated to ensure
the highest quality.
Acrylic coatings are
recommended primarily
for interior or limited
residential and institutional
applications. Acrylic
coating meets the physical
test requirements of
AAMA Specification 603,
which covers pigmented
organic coatings on
extruded aluminum. Acrylic
coating provides good
film integrity, color
control, impact and
mar resistance. Acrylic
coatings can be applied
over inhibitive primers
to enhance corrosion
resistance for coastal
or industrial exposures.
ANODIZING:
Anodizing
is an electrochemical
process that thickens
and toughens the naturally
occurring protective
oxide. The resulting
finish, depending on
the process, is the
second hardest substance
known to man, second
only to the diamond.
The anodic coating is
part of the metal, but
has a porous structure
which allows secondary
infusions, (i.e. organic
and inorganic coloring,
lubricity aids, etc.)
While
the chemical anodizing
process remains the
same for all applications,
the mechanical methods
vary according to the
two physical types and
shapes of metals used:
TYPES OF ANODIZING:
Batch
Anodizing: Involves
racking parts and immersing
them in a series of
treatment tanks. Extrusions,
sheets or bent metal
parts, castings, cookware,
cosmetic cases, flashlight
bodies, and machined
aluminum parts are just
a few of the items that
are batch
anodized.
Continuous Coil
Anodizing: Involves
continuous unwinding
of pre-rolled coils
through a series of
anodizing, etching and
cleaning tanks, and
then rewinding for shipment
and fabrication. This
method is used for high
volume sheet, foil and
less severely formed
products such as louvers.
BENEFITS OF ANODIZING:
The unique
anodized finish is the
only one in the metals
industry that satisfies
each of the factors
that must be considered
when selecting a high
performance aluminum
finish:
Durability:
Most anodized products
have an extremely long
life span and offer
significant economic
advantages through maintenance
and operating savings.
Anodizing is a reacted
finish that is integrated
with the underlying
aluminum for total bonding
and unmatched adhesion.
Color
Stability: Exterior
anodic coatings provide
good stability to ultraviolet
rays, do not chip or
peel, and are easily
repeatable.
Ease
of Maintenance: Scars
and wear from fabrication,
handling, installation,
frequent surface dirt
cleaning and usage are
virtually non-existent.
Rinsing or mild soap
and water cleaning usually
will restore an anodized
surface to its original
appearance. Mild abrasive
cleaners can be used
for more difficult deposits.
Aesthetics:
Anodizing offers a large
increasing number of
gloss and color alternatives
and minimizes or eliminates
color variations. Unlike
other finishes, anodizing
allows the aluminum
to maintain its metallic
appearance.
Cost:
A lower initial finishing
cost combines with lower
maintenance costs for
greater long-term value.
Health
and Safety: Anodizing
is a safe process that
is not harmful to human
health. An anodized
finish is chemically
stable, will not decompose;
is non-toxic; and is
heat-resistant to the
melting point of aluminum
(1,221 degrees F.) Since
the anodizing process
is a reinforcement of
a naturally occurring
oxide process, it is
non-hazardous and produces
no harmful or dangerous
by-products.
POWDERCOATING:
Liquid
paint is composed of
pigment, resin, and
solvent. Powder paint
is simply pigment encapsulated
in a powdered resin
and is thus simply thought
of as “paint without
the solvent.” Powder
coatings and liquid
coatings made from the
same resin and pigment
will have practically
the same performance
characteristics. For
a given resin, the decision
to use a powder or liquid
coating is simply a
question of application
technique.
Some
resins are more easily
manufactured in liquid
coatings and some are
more easily manufactured
in powder coatings.
Some resins are identified
with either powder or
solvent based coatings,
but not both. Examples
of this are epoxy which
is predominantly a powder
coating and PVDF which
historically has been
manufactured as a liquid
coating. Many of the
perceived advantages
of powders over liquid
coatings such as hardness
and gloss are actually
characteristics of the
resin.
Powder
coatings from most manufacturers
are only available in
large batches and custom
colors can be very expensive.
This is because each
batch of powder must
be ground to order using
expensive grinding equipment.
Solvent born colors
will continue to maintain
their niche in the market
because of the ease
with which small batches
can be mixed. The ability
to "mix and match" gives
painters and their customers
unequalled flexibility
and ease of use.
