What is the difference between AAMA 2604 and 2605?

What is the difference between AAMA 2604 and 2605?

AAMA 2604 powder coatings are formulated with super durable or modified polyester resins. This finish provides good color and gloss retention for approximately five years of exposure. AAMA 2605 is the high-performance exterior specification. These finishes are resistant to moisture, weathering, ozone and UV radiation.

Is standards for powder coating?

Architectural powder coating must meet AAMA 2604 or 2605 standards because, for items like metal railing, fencing, window frames, doors, grills and facades, durability and weather-resistance are critical to both durability and safety.

What does AAMA 2604 stand for?

powder coating
AAMA 2604. AAMA 2604 rated paint is an intermediary level of powder coating. Experts say it should be used for high traffic areas such as on doors or storefronts because of its durability. 2604 ratings. Color retention: 2604 rated paint must maintain an acceptable level of color change over 5 years.

What is a powder coating standard?

A new ASTM International standard describes methods of preparing surfaces of hot-dip galvanized iron and steel for powder coating and the application of powder coating materials.

What is the standard thickness of powder coating?

The normal standard used in powder thickness measurement is the mil, where 1 mil is equal to a thousandth of an inch (1/1000”). So if the manufacturer’s specified thickness is 2 to 5 mils, the final cured thickness of the powder should be between 0.002 and 0.005 of an inch.

What does AAMA stand for powder coating?

American Architectural Manufacturers Association
The American Architectural Manufacturers Association (AAMA) is the authority that determines the ratings for different kinds of powder coats. Powder coating comes in three different ratings. They can be rated as AAMA 2603, AAMA 2604, or AAMA 2605.

What does AAMA stand for?

American Association of Medical Assistants
The CMA (AAMA)® credential designates a medical assistant who has achieved certification through the Certifying Board of the American Association of Medical Assistants (AAMA).

What does AAMA stand for Windows?

There is also a third symbol of window excellence: the certification from American Architectural Manufacturers Association (AAMA). Only some window companies take the AAMA Certification, and Abby Windows and Exteriors is one of them.

How do you measure the thickness of powder coating?

For measuring powder coating thickness, a good rule of thumb is to use a magnetic or eddy current thickness gauge on powder-coated metal substrates. Use an ultrasonic thickness gauge on powder-coated non-metal substrates like plastic and wood.

Is powder coat thicker than paint?

Powder coating achieves a thicker and more consistent finish than you usually get with spray paint. The end result of thermoplastic and thermoset powder coatings are virtually identical. In both processes, you heat the powder to form the color finish on a chosen surface.

What does AAMA mean in healthcare?

What do you need to know about Aama 2603?

AAMA 2603 – in the powder world, the coatings that meet and exceed the performance requirements of this specification are known as a Standard Polyester coating. This type of powder coating is typically used on interior applications like interior façade, retail POS, or commercial storefront in a mall.

Which is ppg coatings meet Aama 2603 specifications?

PPG DURACRON ® Acrylic Extrusion Coatings Duracron extrusion coatings, the first aluminum extrusion coatings offered by PPG more than 40 years ago, are acrylic-based 1-coat systems. With decades of field-proven performance, they meet AAMA 2603 specifications and offer good film integrity, color control and mar resistance.

What kind of Kynar paint meets Aama 2603?

Baked enamel (acrylic/polyester) paints should meet AAMA 2603. The baked enamel coatings are generally harder than the Fluoropolymer (Kynar 500®) PVDF resin-based coatings and often are used for interior application where color retention is not required.

What kind of fluoropolymers meet the AAMA 2605 spec?

Fluoropolymer coatings meet and exceed the AAMA 2605 spec, and there are different types of Fluoropolymers (PVDF, FEVE) that will perform to this level. Most powder companies use 100% FEVE Fluoropolymers to far exceed the AAMA 2605 performance requirements.
