Application and Advantage

 

1. Its a good cleaner, offering an even fine grained surface for the subsequent plating process, obtaining 

good adhesion. 

2. Seldom release NOx gas, good for environment protection.

3. Especially suitable for using in aluminum alloy with high content of silicon(like A356)

4. When the content of copper is more than 1% in aluminum alloy, HN-230 is not recommended to use.
