Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and light-sensitive; containers must be kept tightly sealed after opening to minimize exposure to atmospheric moisture and light, which can degrade the initiator's activity.
