1.Under dry conditions,good ventilation at a temperature not exceeding 30 C,humidity<60%
2.Storage period recommended should not exceed 12 months,in case exceeding 12 months without affecting their free flowing properties, the powder will still have optimal characteristics.
3.Should be protected from excessive heat,humidity,water and contamination with foreign materials such as powder, dust, dirt, etc.
4.Any leftover powder should be kept in an appropriate area that is cool and dry. Do not expose to the air too long as the powder properties may deteriorate with the moisture.
