Embedding paper in resin is a popular technique for preserving memories, artworks, or special notes. But one of the main concerns is whether the paper will turn yellow over time. Here, you’ll find out what affects yellowing and how to help keep embedded paper looking clear and bright.
Why Does Paper Yellow in Resin?
Yellowing of embedded paper can result from two main factors: exposure to UV light and the type of paper used. Over time, UV rays can break down both resin and paper fibres, leading to discoloration. Additionally, standard paper often contains acids that can accelerate yellowing when sealed in resin. Using acid-free paper reduces this risk, especially for long-term displays.
Choosing the Right Resin for Paper Embedding
Selecting a high-quality, UV-resistant resin can significantly slow yellowing. Products like “Trasparente” Multipurpose Clear Epoxy Resin and “Icrystal” both include integrated UV filters, designed to maintain clarity and help protect embedded items from the effects of sunlight. Always ensure the paper is completely dry before sealing, as any retained moisture may cause cloudiness or discolouration.
Top Tips for Best Results
- Choose acid-free, archival-quality paper.
- Work in a dust-free, dry environment so the paper stays pristine.
- Opt for a UV-resistant resin and avoid exposing your finished piece to direct sunlight for lengthy periods.
- Apply a thin sealing layer of resin to both sides of the paper before fully embedding for extra protection.
When This Matters
Yellowing is particularly important if you’re embedding treasured photos, handwritten letters, or artwork within resin for keepsakes or display. Taking precautions from the start will ensure your resin creations remain vibrant for years to come.
