Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature. This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed after each use to prevent absorption of atmospheric moisture, which can affect stability and flow properties.
