Best Resin to Prevent Yellowing or Ambering

What Causes Yellowing in Epoxy Resin?

Epoxy resin can gradually take on a yellow or amber hue when exposed to light, particularly UV rays from the sun or indoor lighting. This discolouration is a natural process but can be significantly slowed by using a product with built-in UV filters. Some resins also benefit from specially designed anti-yellowing formulas, helping preserve their transparent look for much longer.

Choosing a Resin with UV Protection

The most effective way to keep your resin clear is to select one specifically formulated with UV filters. Look for products that clearly indicate UV resistance and, where available, an anti-yellowing warranty. For example, “Icrystal” epoxy resin features a UV filter and a 10-year warranty against yellowing, making it an excellent choice for decorative surfaces, tables, and artwork.

• Always check the manufacturer’s guidance on UV protection.
• Choose resins that list a dedicated UV filter in their specifications.
• Consider the thickness suitable for your project, as this also impacts clarity and performance.

When Yellowing Prevention Matters

Selecting a resin with strong resistance to yellowing is particularly important for items exposed to light, such as tabletops, art, or jewellery. It protects your creative work, ensuring colours remain true and surfaces look fresh over time.
