Packaging：
The material is normally supplied in iron pail with Zinc coating in standard container, 220kgs/drum.
Storage Recomendations：
The SD1433 is hygroscopic and containers must be kept sealed tightly to prevent absorption of moisture, which can adversely affect processing. During the transportation, it should avoid serious shake and strong sunlight. It should be stored in ventilated place, avoiding light, water and fire. Recommended storage temperature is 10～25℃.
