Will These Resins Yellow or Degrade Over Time?

Do Epoxy Resins Yellow Over Time?

Exposure to sunlight and UV rays is one of the main reasons clear resins can develop a yellow tint as years pass. Premium epoxy resins such as “Trasparente” and “Icrystal” are formulated with added UV filters specifically to slow down yellowing and maintain their glass-like clarity. This means, while all resins may show some change if left in direct sunlight for long periods, these are engineered to resist noticeable discolouration and preserve their original finish for years.

Guidance to Prolong Resin Clarity

• Protect from Direct Sunlight: Even with UV filters, keeping resin projects out of intense sunlight extends their clear appearance.
• Store Finished Pieces Wisely: Indoor settings with indirect light are best for long-term display or storage.
• Use Topcoats Where Needed: For outdoor use or high-wear areas, consider an additional UV-resistant clear coat for extra protection.

Regular dusting and gentle cleaning will also help maintain the original gloss and prevent build-up that could dull the surface.

When This Matters

If you’re making furniture, jewellery, art pieces or surfaces where clarity is vital, choosing a resin with integrated UV protection like “Icrystal” is especially important. This is also crucial for works displayed in sunny rooms or conservatories.
