Specifications:

Application:

It is mainly applied in electroplating industry, widely used in pyrophosphate copper plating, bronze plating, copper-tin alloys plating etc.

In cyanide-free electroplating, it can offer Cu2+.
For example: cyanide-free copper plating Cu2P2O7+3K4P2O7==2K6[Cu(P2O7)2]
Complex ion [Cu(P2O7)2]6-exists dissociation equilibrium in aqueous solution:
[Cu(P2O7)2]6-==Cu2++2P2O74

Packing& Storage:

Plastic woven bag or three-in-one paper bag, 25Kg/bag.

Keep in dry, cool and ventilating places.
