Difference Between UV and Epoxy Resin

How UV Resin and Epoxy Resin Work

UV resin is a single-component gel that sets when exposed to ultraviolet light, usually curing fully in just a few minutes. It’s ideal for thin layers and projects that require quick turnaround times, such as adding details to polymer clay or creating small embellishments. For example, “Fairy Wings” UV Resin is ready-to-use and cures in as little as 3-5 minutes under a UV lamp.

Epoxy resin typically comes in two parts (resin and hardener) that need to be mixed before use. It cures through a chemical reaction over several hours, making it well-suited to thicker pours and larger scale creations such as tabletops, art pieces, or larger moulds. Deep pour products like EpoxyTable 5-Five can handle thicknesses up to 5cm per layer, while clear systems like Trasparente are perfect for layers up to 2cm.

Choosing the Right Resin for Your Project

• UV Resin: Best for intricate, low-profile, or small decorative work that benefits from quick setting, like detailed reliefs or jewellery. You’ll need a UV lamp to ensure complete curing.
• Epoxy Resin: Ideal for larger surfaces or deeper layers, such as casting art, furniture, or encapsulating objects. It offers versatility in project size and depth, but requires more curing time and careful mixing.

When This Matters

If you’re working to a tight deadline or want to create fine details, UV resin is highly convenient. For substantial castings and projects that demand durability or thickness, epoxy resin remains the top pick, especially when surface clarity and strength are important.
