Chrome or nickel on Styrene

[bob61727]

Does anyone know what is the best way to go to chrome or nickel plate styrene plastic ? I am trying to find a way I can re-chrome plastic model parts. I have seen a conductive paint on several websites, would this be a simple process of just applying this paint then electroplating or electroforming ?? Are the conductive paints ok to use on styrene plastic??

Thanks
Bob

Caswell's silvaspray works well for me on a variety of substrates. I don't know specifically about Styrene, but I suspect it would work fine.

You might have to use the Caswell sealer concentrate first, to ensure a tight bond for the silvaspray (you'd have to test it with and without). Spray on the silvaspray using an airbrush for a smooth finish and let dry. Proceed then to acid copper, nickel, or copy chrome.

One thing you should consider is that electrocoating the parts may prevent a good fit. The tolerances may be too fine.

I believe there are several postings on this site concerning plastics, toys, models, etc. You may also wish to look at those.

Good Luck!
