Kynar

Product Description Duranar® Sunstorm™ fluoropolymer extrusion coatings are two-coat systems consisting of a patented primer and a durable color coat containing mica pearlescent flakes. Duranar® Sunstorm™ coatings provide a metalescent look without the use of aluminum flakes which require a clear topcoat. The coatings combine PPG proprietary resin and pigment technologies, with 70% of the resin system being made up of Kynar 500® or Hylar 5000® base resins*. Duranar® Sunstorm™ coatings demonstrate proven performance on exterior aluminum surfaces, and are highly resistant to chalking, fading, chipping, and peeling when properly applied by an approved applicator. The coatings are also resistant to dirt collection and chemical staining. They exceed AAMA 2605 specifications and provide exceptional durability and performance in exterior applications.

Anodizing

The anodize finishes are applied by submersing the aluminum extrusion into an acidic solution, and applying a electrical current to the extrusion. The final color is determined by the length of time that the extrusion is left in the solution with the current applied to it. Due to the electrical process the finish becomes infused to the aluminum, thus making it a quite durable finish. Color choices are limited with anodized finishes.

Powdercoating

Powder coating is a dry finishing process that uses finely ground powders of pigment and resin to coat the surface. Powder coating uses an electrostatically charged technique in which the powders are charged so that the powder particles adhere to the metal surface and are then melted and fused together
