Storage Conditions
The product should be sealed in its original packaging container and stored in a dry and ventilated place. In an environment of 18-40ºC, the shelf life is 6 months. If the shelf life is exceeded, analysis is required to determine whether it is still valid.
Due to the storage conditions, this product may experience a small amount of precipitation during storage, which is a normal phenomenon. After stirring evenly, it can be used normally.
