保存环境
1 、Suggest storage temperature and humidity controlled below 40 ℃ and 60 %RH, respectively, for brand new; After opening, please use it up as soon as possible.
2 、After opening for 1 hour, it is a natural phenomenon for moisture regain, implying that moisture content of powder could be increased to 3000 ppm. Suggest drying it again before use.
