The product can be stored under appropriate conditions for two years. But please keep products store in a dry ventilated environment (temperature should not exceed 30°C, in low humidity). Inappropriate storage environment may cause agglomeration. Especially at high temperatures & high humidity, it is recommended not to stack more than 30 days long, it may increase agglomeration phenomenon. Agglomeration does not affect the quality and performance, not a quality problem, but agglomeration material is smashed before using.
