Storage conditions:
The product should be sealed in the original packaging container and stored in a dry and ventilated place. The shelf life is 6 months in an 18-40℃ environment. If shelf life is exceeded, analysis is required to determine whether it is valid.
Due to storage conditions, a small amount of precipitation may occur during storage, which is normal, and can be used normally after mixing.
