3、 Packaging and storage:

20升(sheng)塑桶、30KG/桶。非危險品,按one般化工產品要求貯存。

This product can be stored for a long time. If the temperature is too low, nickel sulfamate tetrahydrate will crystallize and precipitate, which can be dissolved and used at elevated temperature.

4、 Others:

Our company is the first manufacturer to supply domestic nickel sulfamate concentrate in China. In the initial stage, we entrusted a factory in Jiangxi to produce it. In 2009, it was officially produced by Yongding Haohua inorganic salt Co., Ltd.
