Yellowing is a common concern for anyone storing epoxy resin before starting a project. With some careful handling and a few simple precautions, you can help keep your resin clear and ready to use, even after weeks or months in storage.
Key Causes of Resin Yellowing
Resin can yellow during storage mainly due to exposure to sunlight (UV light) and heat. Even ambient, indirect light over time can have a gradual effect, and high temperatures will often accelerate the process. Atmospheric moisture and improper sealing of containers can also contribute to discolouration or cloudiness.
How to Store Resin for Maximum Clarity
- Keep containers tightly sealed: Make sure lids are closed securely to prevent air and moisture ingress.
- Store in a cool, dark place: Aim for a cupboard, drawer, or storage box away from radiators, sunny windowsills, or any heat sources.
- Avoid temperature fluctuations: Consistent room temperatures are best. Do not store resin in garages or conservatories where large daily temperature swings are likely.
Many modern resins, such as the Trasparente Clear Epoxy Resin, include integrated UV filters to help reduce yellowing, but basic care during storage is still vital.
When This Matters Most
Protecting against yellowing is especially important if you buy resin in larger sizes that may not be used all at once, or if you plan to work on multiple projects over time. Preserving clarity ensures professional results when you return to your materials.
