AAMA Releases Document Detailing Organic Coatings Testing

June 2nd, 2014 by DWM Magazine

The American Architectural Manufacturers Association (AAMA) has published AAMA 653-14, Voluntary Performance Requirements and Test Procedures for Organic Coatings on Wood and Cellulosic Composite Substrates. This new document describes test procedures and performance requirements for organic coatings applied to AAMA-certified wood and cellulosic composite substrates for doors, windows and similar products, as defined and specified in AAMA 309-04.

“Although this new document is similar to AAMA 633 for exterior stain finishes released a couple years ago, AAMA 653 is the latest in the AAMA finishes document series and covers organic coatings (or finishes),” says Adam Toft (Arkema Inc), chair of AAMA’s WCCMC Finishes Committee. “The base requirements for organic coatings on different material types includes AAMA 2603, 613, 623, 633 and now 653. All these referenced finish documents show that your finish meets a minimum level of performance. AAMA 653 now provides the ability to demonstrate the same level of performance for a finish on wood and cellulosic substrates.”

The test procedures and performance requirements described in AAMA 653 are specific to factory-applied coatings intended for service in exterior environments. The document will assist architects, owners and contractors in specifying and obtaining factory-applied finishes, which will provide a good level of performance in terms of film integrity, exterior durability and general appearance over the years.
