aama 2605 superior performance
The American Architectural Manufacturers Association (AAMA) 2605 Standard is the highest standard for superior performing organic coatings on aluminum extrusions and panels.
The AAMA 2605 Standard assists the architect, owner, and contractor specify and obtain factory-applied organic coatings that will provide and maintain a superior level of performance. Bunting products are analyzed following AAMA 2605 guidelines with respect to film integrity, exterior weatherability, and general appearance over a period of many years.
AAMA 2605 requires Polyvinylidene Fluoride (PVDF) Resin Technology. The specification requires a 70% PVDF coating composition. If the PVDF drops below 70 percent weatherability suffers. This results in poor performance of the paint finishes.
In the United States, weatherability of architectural coatings is tested in South Florida due to its high UV levels and humidity. This sub-tropical climate provides the harshest test of coating weatherability.
PPG Duranar Coatings have been tested for 10 years in South Florida per AAMA 2605. PPG Duranar coatings, when applied using chromium phosphate pre-treatment, have been found to perform extremely well. As a result they offer a standard 10 year warranty when the pre-treatment is performed to the standards set forth in AAMA 2605. An additional 10 year warranty is available for finishes that receive an extra clear coat - what is otherwise known as an XL Finish.
Bunting's pre-treatment follows AAMA 2605 guidelines and uses a Chromium Phosphate conversion coatings per AAMA 2605 Part 7.2.2
