Storage Instructions
Precaution | Description |
---|---|
Storage Conditions | Store below 25°C to minimize quality loss. For best results, avoid temperatures above 25°C to prevent separation, and below -10°C to prevent freezing. Shake gently before use. |
Storage Stability | Organic peroxides are unstable over time; proper storage reduces quality loss. The product is most stable below 25°C. |
Handling Precautions | Handle with care to prevent damage to the container. Use personal protective equipment. |
