AAMA SPECIFICATIONS for Powder Coating & PVDF Coating

As a normal practice, architects and building owners determine the performance specification required, along with its finish and colour. In order to ensure the coating performance expected, for a given application, one of the three AAMA specifications is adhered to: AAMA 2603, AAMA 2604, or AAMA 2605. These three specifications apply to progressively stronger levels, as indicated by South Florida outdoor exposure and laboratory accelerated testing results. Ameco group is 100% compliant of all AAMA voluntary specifications.

Best of Voluntary AAMA Specifications and other standards for Architectural Powder Coating & PVDF Coating.
