UV Filter for Protection Against Yellowing

If you want your resin creations to stay crystal clear, protection from yellowing is a must. A UV filter within clear epoxy resin offers valuable defence against the long-term effects of sunlight.

What Causes Resin to Yellow?

Epoxy resin, like many clear materials, is vulnerable to ultraviolet (UV) light. Over time, UV exposure can lead to yellow discolouration and dullness. Environmental factors like sunlight, even through windows, will gradually break down the resin’s clarity.

How a UV Filter Works

Resins formulated with a UV filter absorb and reflect much of the harmful light that causes yellowing. Products such as the Icrystal Clear Epoxy Resin are designed with this extra level of protection, helping to preserve brightness and transparency for longer. For best results, keep finished pieces away from direct sunlight when possible.

Tips for Maximising Longevity

Choose resins specifically marked as UV-filtered for clear or decorative pieces.
Store and display creations away from direct sun exposure, such as in shaded rooms or glass-fronted cabinets.
Dust and clean resin surfaces gently to prevent scratches that can further discolour over time.

When Is UV Protection Especially Important?

If you’re crafting jewellery, display items, or figurines intended to keep their bright appearance, UV filtering can make a notable difference. This is particularly true for pieces that will be kept in well-lit environments.
