Epoxy resin: How to reduce or prevent yellowing of the finished product

1 UV Protection

The epoxy resin is a highly versatile and durable material, but unfortunately, it tends to yellow when exposed to UV rays. To prevent this, it is essential to protect epoxy resin artifacts by using transparent varnishes with UV filters. These varnishes create a protective layer that reduces the resin's exposure to direct sunlight, thus preventing yellowing over time. As suggested by RESINPRO, choosing high-quality varnishes is important to ensure better UV protection effectiveness.

2 Using High-Quality Epoxy Resins

Another way to reduce yellowing of the epoxy resin is to use high-quality materials from the start. Low-quality epoxy resins tend to yellow more easily over time compared to high-quality ones that maintain their appearance unchanged over the years. RESINPRO offers a wide range of high-quality epoxy resins ideal for creating transparent and durable artifacts.

3 Avoid High Temperatures During Polymerization

During the polymerization process of the epoxy resin, it is important to avoid excessively high temperatures that could accelerate the material's yellowing. Using a low-power UV lamp and maintaining a constant temperature during the curing phase can help preserve the resin's transparency over time. RESINPRO offers professional UV lamps and other specific tools to ensure optimal polymerization of the epoxy resin.

4 Proper Storage of Epoxy Artifacts

Finally, to prevent yellowing of artifacts made with epoxy resin, it is crucial to store them correctly. Avoid prolonged exposure to direct sunlight and keep the artifacts in cool, dry environments to help preserve their original appearance over time. RESINPRO provides useful tips on the proper storage of epoxy artifacts, as well as specific materials and tools for their care and maintenance.
