Product Usage: It is used for wood preservative ,and in PCB system it is uses for Non-Cyanide Electroplating,overcoming the shortcoming of some Substrate which cannot plated directly,,not only getting the copper plating coating of good quality,but also operating safty with low pollution .Suitable for elecreo-plating of decoratio material(Mg-Al alloy),zipper,spare parts of automobile,machinery material ,jewelry.steel,dairy hardware.
Packaging: 25Kg woven bag with double PE liners, closed tightly.
Storage Precautions: Stored in dry and draughty warehouse. Tie the bag tightly to prevent dampness or caking. Avoid impact; no mixing with strong acids or alkali. Flexible container must be put vertically on the pallet, and fastened with roll paper.
