• Incorporate UV absorbers and weather resistance modifiers. After 720-hour accelerated aging test under xenon lamp, the color difference ΔE is ≤ 2.0 and the retention rate of surface glossiness is > 90%.

• Practical application: After 15 years of continuous use in the coastal high-salt spray environment, no powdering or fading occurred, and the maintenance cost was nearly zero.
