American Architectural Manufacturers Association, a material-neutral organization, is the source of performance standards for the fenestration professionals of window, door, skylight, curtain wall and storefront manufacturing companies. This specification describes test procedures and performance requirements for superior performing organic coatings applied to aluminum extrusions and panels for architectural products.
These paints are somewhat less expensive, but have poor resistance to color fading and chalking. An application for this finish would include monumental architectural projects and projects that require long-lasting aluminum surfaces.
A tester pushes a pencil with F medium hardness held at a degree angle into the film and tries to rupture it. To adhere to the AAMA standards, properly prepared test panels are subjected to the following rigorous tests:. Gloss can also be affected by environmental factors such as weathering or surface abrasion. A degree gloss meter measures newly finished aluminum for a gloss value.

Adherence to AAMA five-year color retention and chalk resistance and AAMA one-year color retention and chalk resistance offer less, though better and good performance levels, respectively. This is a test for a coating lifting off the substrate. The Highest Standard in the Industry In accordance with standards, aluminum extrusions or panels must undergo a surface preparation for a PVDF coating application that involves the following steps: These specifications apply to South Florida outdoor exposure and laboratory accelerated testing results as shown below.
This is a process that treats the metal surface chemically when the metal is immersed in or sprayed with various solutions.
Standards were developed to assure the building community that coatings on extruded aluminum retain their integrity. It also will provide good hardness and abrasion resistance. For all tests, there should be no removal of coating under the tape either within or outside the cross hatched area, nor blistering anywhere on the test specimen. AAMA MEMBER American Architectural Manufacturers Association, a material-neutral organization, is the source of performance standards for the fenestration professionals of window, door, skylight, curtain wall and storefront manufacturing companies.
Please read our simple purchasing instructions first 26605 ensure a smooth transaction. Tape is applied over the deformed area and sharply removed at a right angle to the panel.
This tests the number of years a product is likely to resist wearing off. In places where there are environmental concerns, chrome pretreatment may not be allowed. A tester drop dart impacts the surface in order to deform a small piece of the sample.
Tape is scored in a prescribed cross hatch pattern and adhered to a sample, and then sharply pulled off at a right angle to the plane being tested. When formulated into a coating composition containing a minimum of 70 percent PVDF resin, the resultant coatings exhibit xama color and gloss retention, chalk and corrosion resistance, flexibility, stain resistance, overall durability, and can stand up to direct sun, extreme temperature variations and acidic pollutants without fading.
This tests whether the coating will rupture after impact. American Architectural Manufacturers Association. In this version, an appendix was added describing differences in test procedures and performance requirements for AAMA for Superior Performing Organic Coatings, applied on a coil coating line, to aluminum architectural products.
In the case ofthe AAMA Finishes Committee last refined the document in to support the latest industry knowledge. Linetec has earned a long-standing reputation as a leader in environmentally-conscious practices and finishing options.
Coatings should 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 10 feet 3 m from the metal surface and inspected at an angle of 90 degrees to the surface. Subscribe to Architectural Record.
A standard which defines the performance requirements for superior organic coatings on aluminum extrusions and panels. For years, architects recognized and as standards for organic coatings on architectural aluminum and panels.
AAMA 2650 the highest industry standard available, ensuring ten-year color retention and chalk resistance. CAD detail project gallery.
