Letter 10035 Brass electroplating on to plastics
I have problems to plate plastics with brass. First I plate copper to the plastics and then the brass, but after I plate with brass there are many black spot on the product. Does anyone have opinion for this case? Kusuma Purnaman
Mister Purnaman, You need plating nickel after copper, because is the correct method for plating brass in any surface not only on plastics. So, copper, bright nickel and after brass. Good luck, Rafael Arencibia
Dear sir, Plz specify that after brass plating on copper surface, are you using a laquer also on the brass surface? Because brass has a property of getting tarnished very quickly with time in contact with environmental factors viz.moisture ,temp, etc you find black spots on the brass surface. So to protect the brass coating give the plated material a dip in laquer. Good luck, Sandeep Jain
Dear Reader: please choose what you want to do.
