Preventing Yellowing in Epoxy Resin ED

How UV Filters Reduce Yellowing

Epoxy resins like Icrystal and “Trasparente” are formulated with integrated UV filters. These additives act to minimise the resin’s reaction to sunlight, which can otherwise cause discolouration or a yellow tint over time. While no epoxy is completely immune to the effects of UV exposure, these resins are designed to prolong the clarity and preserve a transparent, crystal-like finish for as long as possible.

Choosing and Using UV-Resistant Epoxy Resins

To maximise long-term clarity, always select a resin explicitly designed for UV resistance. For example, “Icrystal” is ideal for transparent surfaces in furniture or artwork, providing scratch resistance and a stable appearance, while “Trasparente” excels in detailed casting projects where colour preservation is key. Consider your project’s requirements, such as pour thickness and exposure levels, and opt for staged applications if making thicker pieces. Storing completed items away from intense sunlight also helps reduce the risk of yellowing.

When This Matters Most

• Outdoor pieces, table tops, and wall art exposed to natural light benefit most from UV-filtered epoxy.
• If you’re making decorative or functional items intended to stay clear for years, prioritising a UV-resistant formula is essential for satisfaction.
