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.

Fire Protection

Precaution Description
Small Fire Handling For small fires, use foam or dry powder extinguishers, followed by large amounts of water to prevent re-ignition.
