Application

Used in dye, perfume, mirror making, electroplating and other industries;It is also used as ultra high pressure lubricating oil, bleaching agent, reducing agent, mordant, decoloring agent and analytical reagent for the determination of silver, arsenic, molybdenum and mercury.Strong reducing agent.

Used as reducing agent, mordant, acid tin plating, main salt.It is used in glass mirror industry as an sensitizer for silver nitrate plating, which can make the coating brightness good, and the coating of this product is not easy to fall off when ABS electroplating.
