Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is moisture-sensitive (hygroscopic) and should be kept under an inert atmosphere (e.g., nitrogen) after opening to prevent degradation and polymerization. Keep away from heat, sparks, and open flame.
