Copper plating process for zinc die casting using no cyanide strike.
"DAIN COPPER PSR-SZ" is the industry's first cyanide-free copper plating solution that uses monovalent copper ions. Due to the inclusion of a special complexing agent, there is no substitution with the substrate at all, and the electrodeposited film shows excellent adhesion. It has made it possible to perform cyanide-free copper plating on zinc die-cast materials, which has been difficult until now.
