Best Resin Options for Preserving Insects in Epoxy

← Back to How to put insects under resin?

Encasing insects in resin is a creative way to preserve their natural beauty for years. Choosing the right epoxy resin is essential to achieving a clear, lasting result and ensuring your project runs smoothly.

Choosing the Right Epoxy Resin

The most important consideration is the thickness of your resin pour. For small projects where layers don’t exceed 1.5cm, a high-quality, odourless resin such as “Icrystal” – Clear Epoxy Resin offers excellent clarity and is easy to use in detailed moulds. For slightly thicker castings up to 2cm, “Trasparente” Multipurpose Epoxy Resin provides durability with a crystal-clear appearance. If your design requires deeper embedding—such as an artistic block or a large display piece—consider a specialist deep pour resin like EpoxyTable 5-Five, which supports pours up to 5cm thick without excessive heat buildup or yellowing.

Tips for Achieving a Clear Finish

To highlight the details of the insect, select an epoxy resin with a non-yellowing, UV-resistant formula. Always pour in suitable layers for your resin’s recommended thickness, letting each layer cure properly before the next. This helps prevent bubbles and ensures the specimen remains suspended in the centre of the cast. Avoid overheating by staying within recommended depth limits for each resin, and refrain from using excessive heat sources during the curing process.

When Pour Depth Matters

The depth of your casting directly affects which resin to use and the final result. For jewellery or small keepsakes, shallow pours up to 1.5–2cm are ideal. Larger, more substantial pieces benefit from deep pour resins specially designed for thicker layers, ensuring a strong and even cure without risk of cracks or cloudiness.
