How does UV radiation affect the color stability of resin-based outdoor sculptures?
UV radiation significantly impacts the color stability of resin-based outdoor sculptures, leading to gradual fading and discoloration. Prolonged exposure to sunlight breaks down the polymer chains in the resin, causing chemical changes that alter pigmentation. Over time, vibrant hues may dull or turn yellowish, especially in cheaper or non-UV-resistant resins. To mitigate this, artists often use UV stabilizers or protective coatings, but even these require periodic maintenance. Understanding this process helps collectors and creators preserve outdoor resin art for longer-lasting visual appeal.
