  • AAMA 2604 is applicable to a cured film thickness of at least 2 mils, intended primarily for commercial and architectural-grade applications, utilizing ASTM test methods and performance criteria to evaluate color uniformity, specular gloss, impact resistance and chemical resistance. Compared to AAMA 2603, 2604 include additional test methods and acceptance criteria for abrasion resistance, chemical resistance and weathering. Weathering tests evaluate color retention, chalk resistance, gloss retention and resistance to erosion after mandatory extended outdoor test exposure in the South Florida environment. AAMA 2604 recognizes high-performance coatings that could involve non-chrome pretreatments, a necessity in some markets where chrome pretreatments are not allowed due to environmental concerns over the use of heavy metals.
