Is Epoxy Resin Safe for Photos or Paper Inclusions?

Choosing a Suitable Epoxy Resin

Not all resins are the same when it comes to clarity and temperature. For paper or photographic inclusions, a clear, low-exotherm resin is essential to prevent distortion or damage. Options such as “Trasparente” – Multipurpose Clear Epoxy Resin for Casting – Up to 2cm and “Icrystal” – Clear Epoxy Resin – Odourless Formula – Up to 1.5cm perform well for this purpose, offering outstanding transparency and gentle processing temperatures.

Preparing and Sealing Your Inclusions

Before embedding any photos or paper, it’s crucial to seal them. This protects delicate surfaces from resin absorption and prevents discolouration or unwanted reactions. Use a suitable paper sealer, spray adhesive, or clear-drying medium, ensuring the item is completely dry before casting. This step helps retain vibrant colours and crisp details throughout the curing process.

Practical Guidance for Successful Casts

• Work in layers if needed—pour a thin layer of resin as a base, allow it to set slightly, then place your paper.
• Press the inclusion gently to eliminate trapped air bubbles.
• Keep the casting depth within the recommended limits of your chosen resin (e.g., 1.5–2cm per layer).

These methods provide the best results for preserving both aesthetics and structural integrity.
