Always keep release agents tightly sealed in their original containers to prevent evaporation, drying out, or contamination. Store them in a cool, dry place away from direct sunlight and sources of heat, as temperature fluctuations can degrade product performance over time. Silicone oil : Ensure lids are firmly closed to avoid leaks or dust ingress. Release waxes : Re-cap containers after every use and wipe away residues from rims. Glossy release films : Roll or store flat in their packaging to prevent creasing, and shield from direct light exposure.

How to Store Resin Release Agents Properly

← Back to How do you make resin mould release?

Proper storage of release agents such as silicone oil, release wax, and glossy films extends their effectiveness and keeps your resin crafting projects running smoothly. Here’s how to look after these essential materials between uses.

General Storage Tips

Always keep release agents tightly sealed in their original containers to prevent evaporation, drying out, or contamination. Store them in a cool, dry place away from direct sunlight and sources of heat, as temperature fluctuations can degrade product performance over time.

Silicone oil: Ensure lids are firmly closed to avoid leaks or dust ingress.
Release waxes: Re-cap containers after every use and wipe away residues from rims.
Glossy release films: Roll or store flat in their packaging to prevent creasing, and shield from direct light exposure.

Handling to Prevent Contamination

Contamination can reduce the effectiveness of your release agents. Always use clean tools for application—for example, a dedicated brush for waxes or clean gloves when handling films. Avoid double-dipping or mixing utensils between products. If you’re using a product like Silicone Oil for Mould Protection and Easy Release, decant only what you need into a smaller, clean container for application and immediately reseal the main bottle.

When Proper Storage Matters

Storing your release agents correctly really matters if you work with resin infrequently, have multiple open products, or live in a space with fluctuating temperatures. Proper care ensures your materials perform reliably and saves money by reducing waste and spoiled batches.
