This is a test for a coating lifting off the substrate. To adhere to the AAMA standards, properly prepared test panels are subjected to the following rigorous tests:.
The sample is removed and wiped dry and the adhesion test is repeated. Paint that lifts off is measured as a percentage failure rate. In accordance with standards, aluminum extrusions or panels must undergo a surface preparation for a PVDF coating application that involves the following steps:. During manufacturing, a 6205 bond is created between the extruded aluminum and the paint to resist chalking and fading.
This specification covers factory-applied spray coatings only. If needed, the DMC asks the appropriate committee to review and refine the document.

Tape is applied over the deformed area and sharply removed at a right angle to the panel. The panel with tape over the cross hatch patterns should be immersed in distilled or de-ionized water at degrees F for 24 hours.
These finishes exhibit outstanding resistance to humidity, color change, chalk, gloss loss and 2650. Color uniformity must be consistent with color range or numerical value established between the approval source and the applicator.
As important as the paint color, architects, specifiers and building owners must determine which performance specification is required.
Gloss consistency is tested from one unit to another. The purpose of these standards is to help architects, contractors, and building owners specify factory-applied organic coatings that will provide and maintain a superior level of performance in terms of coating integrity, exterior weatherability, and general appearance over many years. This tests whether the wama will rupture after impact.
A one-year South Florida weathering test is optional. The American Architectural Manufacturers Association AAMA is a awma of finish performance standards, product certification and educational programs for the window, door, and skylight industry. Salt Spray 4, hours 3, hours 1, hours Humidity 4, hours 3, hours 1, hours Warranty 10 Year 5 Years 1 Year.
This test is conducted in three categories: While AAMA addresses complete coatings systems based on 30mg of chrome pretreatment; AAMA applies to high-performance coatings based on 40mg of chrome pretreatment Both coating aamz may use a non-chrome pretreatment process.
AAMA applies to polyester and acrylic coating and is intended primarily for interior, light commercial and residential-grade coatings of at least 20 microns 0. 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. Gloss is always referenced against a standard. CAD detail project gallery.
For more than a decade, environmental responsibility has been written into our core values. Subscribe to Architectural Record.
The sample panel should then be removed and wiped dry, after which 2650 film adhesion test is repeated. In addition, the same impact resistance and chemical resistance are used in both standards. Linetec has earned a long-standing reputation as aamw leader in environmentally-conscious practices and finishing options. The most recent AAMA standards reflect good, better, and best performance for extruded aluminum clad windows:.
Acid or alkaline wash to remove impurities A fresh water rinse Chemical conversion—a chromium or non-chromium pretreatment. AAMA maintains specifications for all fenestration materials.

Boiling Water Film Adhesion: When formulated into a coating composition containing a minimum of 70 percent PVDF resin, the resultant coatings exhibit superior 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 specification describes test procedures and performance requirements for superior performing organic coatings applied to aluminum extrusions and panels for architectural products.
In places where there are environmental concerns, chrome pretreatment may not be allowed. Color Retention 10 yrs: The same ASTM test methods and performance criteria are used to evaluate color uniformity and specular gloss, which is a measure of the light reflected by the surface of a material.

For years, architects recognized and as standards for organic coatings on architectural aluminum and panels. This is a test for susceptibility to damage that might be sustained during shipping or installation.
This tests the number of years a product is likely to resist wearing off. Adherence to these standards enables architects to make reliable projections about product performance. Film does not rupture. Please read our simple purchasing instructions first to ensure a smooth transaction. Begin your publication search by entering information into the fields below.
