What Makes Epoxy Clearer Than Other Resins?

How Epoxy Achieves Superior Clarity

Epoxy resins are engineered for optical clarity. Top brands use carefully balanced chemical formulations that reduce natural yellowing and provide a true „liquid glass“ effect. This makes epoxies ideal for uses where seeing textures, inclusions, or vibrant colours beneath the surface is essential—such as in table coatings, jewellery and artwork.

For instance, Icrystal Clear Epoxy Resin is designed specifically to maximise transparency thanks to its advanced resin and hardener blend.

Why UV Filters Matter

While all resins may look clear when first poured, many turn cloudy or yellow over time, especially when exposed to sunlight. High-quality epoxy resins integrate UV filters, effectively slowing down the rate of yellowing and hazing. This keeps finished pieces looking bright and clear for years, a crucial advantage over many polyester or polyurethane alternatives.

Tips for Achieving the Best Clear Finish

• Mix accurately: Follow the manufacturer’s ratio closely for proper curing and clarity.
• Work in clean conditions: Minimise dust and bubbles to keep the cured resin free from cloudiness.
• Layer properly: For thicker castings, select an epoxy suitable for your desired depth; some formulas, like Icrystal, are perfect for layers up to 1.5cm without losing transparency.
