Six, storage, transportation and Cautions:
1. Such products of non-dangerous goods, as a general storage and transportation of chemicals, product packaging, see barrels of storage period.
2. Please see the product model, and then pigeon-holing; accurate weighing, please give full uniform mixing.
3. When potting impregnation speed not too fast, in order to ensure uniform impregnation.
Seven, packaging specifications: Packing for A: 25KG or B: 5KG.

Note: The above performance data for the product in 70% humidity, the temperature at 25 ℃ typical testing data, only use customer information and can not guarantee that in a particular environment can be achieved when all the data. Please use customers to the measured data.
