  • Exposure: The main difference between AAMA #2604 and AAMA #2605 is their longevity. AAMA #2604 powder coatings can withstand exposure for around five years. The finish will continue to retain gloss and color during this time span. AAMA #2605 is more resistant. This high-performance coating will deliver protection for around 10 years.
  • Use: Due to the variance in lifespan, these two products are typically chosen for different uses. Because it offers more long-term protection, AAMA #2605 is more appropriate for architectural projects that will need to endure exposure. This makes it a better choice to use on aluminum cladding.
  • Corrosion: Part of the enhanced durability of AAMA #2605 is a greater resistance to corrosion. On average, AAMA #2604 may begin to experience corrosion after 3,000 hours of exposure. In contrast, AAMA #2605 will last around 4,000 hours before starting to corrode.
  • Preparation: To apply either coating involves a similar process. The powder coating is applied to the aluminum or other material, then it is placed in a curing oven where it is heated at extremely high temperatures based on product specifications. Lastly, the products are tested to ensure they meet set standards for AAMA #2604 or AAMA #2605.
  • Testing: Whether coated with AAMA #2604 or AAMA #2605, products are tested in a similar fashion to ensure they meet AAMA specifications. These tests include adhesion, weathering resistance, chemical resistance, dry film hardness, impact resistance, humidity resistance, abrasion resistance and corrosion resistance. These tests determine how well the coating will protect the material and how its aesthetic qualities will hold up over time.
  • Standards: In order to meet the standards for AAMA #2605, the coating’s color, chalking and gloss retention must remain within the specified ranges after testing in Florida for 10 years. Similar standards are set for AAMA #2604, but the timeframe is a five-year testing span.
  • Applications: To determine which powder coating is right for your project, it’s important to consult with professionals who can offer in-depth insight into these products.
