Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Recommended storage temperature is between 2°C and 8°C (refrigerated) for long-term stability to minimize potential degradation or polymerization. Keep away from heat, sparks, and open flames. The container should be kept tightly sealed when not in use to prevent moisture absorption and volatilization.
