What Causes Yellowing on Resin Statues?

← Back to How to restore a resin statue?

Yellowing is one of the most common issues resin statue owners face as their pieces age. Understanding why it happens can help you preserve the original beauty of your resin artwork for longer.

Main Causes of Yellowing

The two chief culprits behind resin yellowing are exposure to ultraviolet (UV) light and the use of lower-grade materials. When resin statues are placed in direct sunlight or harsh artificial lighting, the UV rays gradually degrade the resin, causing it to lose its clarity and develop a yellow or amber tone. Additionally, resins that lack UV inhibitors or contain low-quality pigments are far more likely to yellow over time, even in indoor environments.

How to Minimise Yellowing

To protect your resin statues from yellowing, opt for resins that feature built-in UV filters, such as the Icrystal Clear Epoxy Resin or Art Pro Deluxe, both of which are specially formulated to resist UV degradation. Always display your resin pieces away from direct, intense sunlight whenever possible. For statues already showing surface dullness rather than deep yellowing, a polishing system like Epoxy Polish can help restore clarity and enhance gloss.

When This Matters Most

If your resin art is displayed in sunlit rooms, conservatories, or bright studio spaces, taking preventive steps is especially important. This is also crucial if you create or sell resin statues and want your work to maintain its finish for years.
