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.
