POWDER COATING PROCESS
Using AAMA 2604 & 2605 powder coating specifications:
Our powdering coating process is designed to meet or exceed the AAMA 2604 powder
coating standard. AAMA 2605 is available if special ordered.
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 two AAMA specifications should be referenced:
AAMA 2604 and 2605.
