Product packaging

The special iron barrel is sealed and packed, and the inner layer is made of moisture-proof plastic bags, with a net weight of 100kg/barrel;

Packed in half-ton bags, lined with moisture-proof material bags, net weight 500 kg/bag.

Precautions for storage, transportation and use

I. Pay attention to waterproof and moisture-proof, and prohibit contact with other chemicals and hydrocarbon substances;

II. Do not drop or roll the iron bucket during handling;

III.. When the product is used, the water absorption should be tested correctly to avoid rapid moisture absorption in wet weather affecting the impregnation load.
