Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at room temperature (15-25°C). Due to its hygroscopic nature, the container should be kept in a desiccated environment to prevent moisture absorption, which can affect material properties. For long-term storage, consider using an inert atmosphere (argon or nitrogen).
