How does UV exposure affect the color stability of resin-based outdoor sculptures?

UV exposure is a significant factor in the degradation of resin-based outdoor sculptures, particularly affecting their color stability. Over time, prolonged exposure to sunlight causes the resin material to break down at a molecular level, leading to fading, yellowing, or discoloration. The ultraviolet rays accelerate oxidation and photochemical reactions within the resin, weakening its structural integrity and altering its appearance.

To mitigate these effects, artists and collectors can apply UV-resistant coatings, use pigments with high lightfastness, or position sculptures in shaded areas. Regular maintenance, such as cleaning and reapplying protective sealants, also helps preserve the sculpture's vibrancy. Understanding these factors ensures that resin-based outdoor art remains visually appealing for years to come.
