5、the architectural community has recognized AAMA 603 and AAMA 605 as the standards for testing and performance of organic coatings on architectural aluminum extrusions and panels. Significant advances have been made in technology which have created the need to revise these specifications. AAMA 2603,

8、luntary Specification for High Performance Organic Coatings on Architectural Extrusions and Panels;“ as well as all revisions to these documents. AAMA 2604 is a new five-year high performance specification similar in performance criteria to the original version of AAMA 605.2-92 (the original version
9、 does not include any subsequent Addenda) with the exception of the pre-treatment section, which allows for non-chrome pre-treatment. 1.0 SCOPE 1.1 This specification describes test procedures and performance requirements for high performance organic coatings applied to aluminum extrusions and panel
10、s for architectural products. 1.2 This specification covers factory-applied spray coatings only. 1.3 The primary units of measure in this document are metric. The values stated in SI units are to be regarded as the standard. The values given in parentheses are for reference only. 2.0 PURPOSE The spe
11、cification will assist the architect, owner and contractor to specify and obtain factory-applied organic coatings which will provide and maintain a high level of performance in terms of film integrity, exterior weatherability and general appearance over a period of many years. 3.0 DEFINITIONS 3.1 Th
12、e terms “film“ and “coating“ are used interchangeably in this specification and are defined as meaning the layer of organic material applied to the surface of the aluminum. 3.2 Exposed surfaces are those surfaces which are visible when the coated product is installed. These may include both closed a
13、nd open positions of operating sash, ventilators, doors or panels. 3.3 Spray Coating: The process of applying a resinous coating by atomizing it into a spray or mist, and curing it into a continuous film. 4.0 GENERAL 4.1 To qualify as meeting this specification, products tested shall meet all requir
14、ements as specified herein. 4.2 Coatings shall be visibly free from flow lines, streaks, blisters or other surface imperfections in the dry-film state on exposed surfaces when observed at a distance of 3 m (10 ft) from the metal surface and inspected at an angle of 90 degrees to the surface. 4.3 The
15、 total dry-film thickness shall be assessed utilizing the ASTM D 1400 method. Eighty percent of measurements on primary exposed surfaces shall meet or exceed 30 microns (1.2 mil) total film thickness. Paint process capability may result in readings below 25 microns (1.0 mil). No more than 5% of the
16、total readings, on primary exposed surfaces, shall be below 25 microns (1.0 mil) (or, 85% of film thickness specified), assuming appropriate color and hide. Film thickness specified may be increased to be consistent with color selection and type of coating as recommended by the coating manufacturer. NOTE: Due to the complexities of extrusion dies and limitations of application equipment, it may not be possible to achieve minimum recommended dry film thickness on all areas of an extrusion,
