Application

Used in electrogalvanizing and preparation of steel phosphatizing agent, printing and dyeing mordant, acidification catalyst, gel, catalyst of latex, metal surface treating agent, etc. At present, it is widely applied in various machinery products, instruments, bikes, sewing machines, refrigerator, automobile, ship or phosphating, it can also be used for phosphating and lubricating treatment in the cold drawing of seamless steel tube, steel wire.

Packing, transportation and storage:
50kg plastic woven bag lined with two-layer PE bag film with high density. It should be covered during transportation, pay attention to rain and damp. Can not be mixed transported with plastic or food. Please keep in dry and ventilated warehouse, it is corrosive and toxic, thus protective measures are required.
