Architects and building owners should determine which performance specification is required, along with the finish color. In order to ensure the powder coat performance expected for a given application, one of three AAMA specifications should be referenced: AAMA 2603, 2604, and 2605. These three specifications apply to progressively stronger levels as indicated by South Florida outdoor exposure and laboratory accelerated testing results as shown below.
|South Florida Weathering:|
|Color retention||1 year: "slight" fade||5 yrs: Fade = 5 Delta E||10 yrs: Fade = 5 Delta E|
|Chalk resistance||1 year: "slight" chalk||5 yrs: Chalk = 8||10 yrs: Chalk = 8|
|Gloss retention||No specification||5 yrs: 30% retention||10 yrs: 50% retention|
|Erosion resistance||No specification||5 yrs: 10% loss||10 yrs: 10% loss|
|Dry film thickness||0.8 mils minimum||1.2 mils minimum||1.2 mils minimum|
|Pretreatment System:||Chrome or Chrome Free *||Chrome or Chrome Free *||Chrome or Chrome Free *|
|Salt Spray||1,500 hours||3,000 hours||4,000 hours|
|Humidity||1,500 hours||3,000 hours||4,000 hours|
