AAMA 2605 — Voluntary Specification, Performance Requirements and Test Procedures for Superior Performing Organic Coatings on Architectural Aluminum Extrusions and Panels

American Architectural Manufacturers Association (now FGIA)

The top-tier specification for organic coatings on architectural aluminium, covering fluoropolymer (typically PVDF-based, e.g. Kynar 500 / Hylar 5000) coatings rated for 10-year South Florida natural-exposure weathering. Specifies salt-spray (4000 hours per ASTM B117), chalk resistance, gloss retention (≥ 50% at 10 years), and colour fade limits. The reference for premium architectural finishes globally.

AAMA 611 — Voluntary Specification for Anodized Architectural Aluminum

American Architectural Manufacturers Association (now FGIA)

The reference voluntary specification for anodic coatings on architectural aluminium in North America and internationally. Defines Class I (≥18 μm coating thickness, sealed, full architectural-grade performance) and Class II (≥10 μm, lower-tier exterior exposure). Specifies weathering performance via accelerated and natural-exposure testing, salt-spray (per ASTM B117, 336 hours for Class I), abrasion resistance, sealing quality, and colour-stability requirements. The most-cited architectural anodize standard in international façade specifications, including in Indian high-end architectural projects.

AAMA 2604 — Voluntary Specification, Performance Requirements and Test Procedures for High Performance Organic Coatings on Architectural Aluminum Extrusions and Panels

American Architectural Manufacturers Association (now FGIA)

The mid-tier specification for high-performance organic (typically polyester or polyester-urethane) coatings on architectural aluminium. Specifies film performance requirements including 5-year South Florida natural-exposure weathering, salt-spray resistance (3000 hours per ASTM B117), abrasion resistance, hardness, and chemical resistance. Sits between AAMA 2603 (short-exterior, lower-tier) and AAMA 2605 (10-year, fluoropolymer).
