Description
This is a super-durable polyester-HAA smooth metallic powder coating combining a higher level of long-term exterior weathering performance with a metallic decorative finish. The coating is based on a super-durable polyester-HAA system and is suitable for applications requiring 11–18 years of outdoor weathering durability, with performance comparable to Qualicoat Class 2, AAMA2604 and GB/T 5237.4-2017 (Class II) requirements. A 160°C low-temperature curing option is available. The formulation is TGIC-free, complies with applicable REACH restrictions, and is suitable for relevant markets including Europe. For super-durable metallic coatings, long-term appearance retention is influenced not only by the base resin system but also by the metallic pigment and its surface treatment. Metallic appearance is particularly sensitive to spray voltage, gun distance, film thickness, part geometry and reclaimed-powder use, and tonal variation may occur when application conditions change. For long-term exterior projects, the metallic appearance should be confirmed with the actual formulation and sample panels, while weathering performance should be validated against project requirements. Stable application parameters and controlled reclaim management are recommended for production consistency.
