IFS & AAMA Powder Coatings

AAMA (American Architectural Manufacturers Association,) sets the standards for coating performance on architectural applications. AAMA produces 3 different level of ‘Voluntary Specification Performance Requirements and Test Procedures for Pigmented Organic Coatings on Aluminum Extrusions and Panels’. These are AAMA 2605, AAMA 2604 and AAMA 2603 and each requires a different level of coating testing and performance.

To meet the AAMA specifications, coated panels are put through a series of tests to determine how the aesthetic and protective qualities of the coatings perform.

AAMA tests include:

  • Dry film hardness
  • Adhesion
  • Impact resistance
  • Abrasion resistance
  • Chemical resistance
  • Corrosion resistance
  • Humidity resistance
  • Weathering resistance

The AAMA coatings specifications are particularly important when dealing with weathering (exterior durability) performance. To ensure the aesthetic properties of the coating are maintained over time, coated panels are tested in Florida (actually known as Florida testing) for ten (AAMA 2605), five (AAMA 2604) and one (AAMA 2603) years. The Florida weather allows the coatings to be continuously exposed to harsh UV light, humidity and salt air. After exposure to these conditions, the aesthetic properties, namely color and gloss, are measured.

At each level of AAMA powder coatings, they outline basic requirements such as:

  1. Multi stage cleaning and pre-treatment are required and essential to preparing the substrate to receive the powder coating and allow the powder to cover and protect the surface as efficiently as possible.
  2. Coatings shall be visibly free from flow lines, streaks, blisters or other imperfections in the dry film state on exposed surfaces when observed at a distance of 3m.

 

The 3 AAMA coating specifications

AAMA 2605

AAMA 2605 requires that coated panels are tested in Florida for 10 years. At the end of the testing, the color must not change more than 5 Delta E units. Chalking must not be more than a number 8 rating based on the ASTM 4214 test and there should be a minimum of 50% gloss retention.

IFS and AAMA 2605

IFS has a full range of high performance Fluoropolymer powders that meet and exceed the performance requirements of AAMA 2605. These are called IFS 500FP. Using state of the art FEVE resin systems, these high performance coatings will ensure a world class AAMA 2605 level performance. IFS 500FP coatings are suitable for commercial and monumental windows, doors, skylights and curtain wall. Warranties up to 20 years are available for IFS 500FP Fluoropolymer powder coatings when applied to architectural aluminum by an IFS Certified Applicator.

AAMA 2604

AAMA 2604 requires that coated panels are tested in Florida for 5 years. At the end of the testing, the color must not change more than 5 Delta E units. Chalking must not be more than a number 8 rating based on the ASTM 4214 test and there should be a minimum of 30% gloss retention.

IFS and AAMA 2604

IFS has a full range of high performance powders that meet and exceed the performance requirements of AAMA 2604. These are sold as IFS 400SD.
Using super durable polyester resin systems, these coatings will meet and exceed the performance requirements of AAMA 2604 and are suitable for applications such as residential and commercial. Both 5 and 10 year warranties are available for IFS super durable powder coatings when applied to architectural aluminum by an IFS Certified Applicator.

AAMA 2603

AAMA 2603 requires that coated panels are tested in Florida for 1 year. At the end of the testing, checking, cracking, crazing or loss of adhesion after taping and only slight chalking and fading should occur to the coating.

IFS and AAMA 2603

IFS has a full range of powders that meet and exceed the performance requirements of AAMA 2603. These are sold as IFS 300SP. Using standard polyester resin systems, these coatings will ensure a solid AAMA 2603 level performance and are suitable for applications such as residential windows, doors, skylight, fencing, fixtures and handrails.
