What are the best ACP finishes for coastal or humid environments?
Coastal and humid climates subject ACP panels to salt spray, high UV exposure, and moisture. To withstand these conditions, PRANCE recommends PVDF (Kynar) finishes or high-build polyester powder coats formulated for marine environments. PVDF coatings offer superior UV resistance and chemical inertness, backed by 20-year warranties. They retain color and gloss, resisting chalking or fading under intense sunlight.
High-build polyester powders—applied at 60–80 µm thickness—provide a robust barrier against corrosion and abrasion. Special resin blends and corrosion-inhibiting pigments further enhance performance in salt-laden air. These finishes also cure into a hard film that resists mold and mildew.
Before coating, aluminum substrates undergo pretreatment with conversion layers (e.g., chromium-free oxide) to improve adhesion and corrosion resistance. Quality control includes salt spray (ASTM B117) and humidity chamber testing to validate long-term durability. With these finishes, ACP facades remain vibrant and corrosion-free in the harshest coastal environments.
