Conductive Coatings

We’ve heard of shops coating the parts with a conductive paint and then plating on top of it. Where can I find some information on that process?

Q. We are a custom job shop specializing in “show” quality chrome plating. We are encountering a lot of die cast parts that are corroded so severely that we can’t get them to plate. We drill out and fill the pits, but the gray and white corrosion in the metal causes several problems. We’ve heard of shops coating the parts with a conductive paint and then plating on top of it. Where can I find some information on that process? B. K.

 

A. Many years ago I developed conductive paints in the laboratory for another project. At that time, we demonstrated they also work in electroplating and electrocoating applications. Where to get them is another question. Guess what? A quick scan of the 2006 Products Finishing Directory and Technology Guide shows a listing for suppliers of Metallizing Sprays and Conductive Paints on page 329. I’m sure the supplier’s representative will be able to provide the information you need.
