Very good quality flux. Did an extraordinary job in soldering over Stainless Steel, mild steel, galvanised iron plates. I tried in all possible materials. But it doesn’t work in cast iron. I’m happy in its performance But, the quantity is not as mentioned in the webpage. It literally had half container only. That’s y I reduced 2 stars. Otherwise 5stars

I had purchased for steel nickel plating soldering or Li-Ion batteries. Thought it won't work. But it is working like a charm. Happy with it. Need mask and gloves for precaution. But it's okay if using small quantity using steel pin or wood stick. Solder attaching well like a glue. You can clean after using thinner or isopropyl. NC thinner is more effective for this product. It's act like a think solder mask liquid. Only used in steel products. For repair works. You can solder anything even a steel charging pin.

Working fine on copper, stainless steel. but not suitable for aluminium.. buy again.

Excellent chemical to solder wire on lithium battery
