Duranar^® Sunstorm Coatings
Data Sheet

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.

System Overview

Duranar^® Sunstorm^™ extrusion coatings offer outstanding performance and durability in a variety of exterior applications where a metallic or metalescent look is desired for aesthetic purposes. With over 10 years of exposure data backing its performance, this two-coat system provides a combination of value, durability, and brilliant appearance in a wide range of colors ranging from white pearlescent to copper, silver, and gold. (A complete list of colors is available from your PPG coatings representative.) Duranar^® Sunstorm^™ two-coat systems can be applied "wet-on-wet" with nominal coating thicknesses of 0.25 mil primer and 1.0 mil minimum topcoat.

Commercial Uses

Duranar^® Sunstorm^™ spray-applied extrusion coatings are formulated to provide exceptional performance against weathering in all environments. (Where added protection against industrial or seacoast influences such as corrosive chemicals, salt spray, etc. are required, Duranar^® XL coatings are recommended.) The two-coat Duranar^® Sunstorm^™ coating is an excellent choice for use on pre-formed aluminum components such as storefronts, curtainwalls, windows, and louvers.

Durability

Duranar^® Sunstorm^™ coatings are chemically inert, providing outstanding resistance against color and gloss fade as well as environmental stress such as acid rain and ultraviolet attack. All pigments are tested for a minimum of five years in south Florida prior to approval for use in any Duranar^® Sunstorm^™ coating system. Additionally, Duranar^® Sunstorm^™ coatings are tested at exposure sites throughout the world in all types of climatic and industrial conditions to ensure the coatings' performance and durability.

** The appearance of metallic and pearlescent finishes may vary upon factory
      application due to differences in spray equipment, spray techniques, film thickness,
      and curing conditions. It is strongly recommended that final color approval is made
       from actual production pieces, including clear top coat when required, not laboratory
       prepared samples. Limits for acceptable production variations are to be established
       between the approval source and applicator.
