Powder Coating ABS
I work for a company that produces decorative finishes in PVD, electroplating and color powder coating. Our product is made of assembled components of brass, zinc and ABS plastic; none of which cause particular problems with the finishing techniques with the exception of powder coat on plastic. This is a very perplexing problem since more and more of our components are being made from plastic—we can’t get them to match the metal components. I have worked with matching plastic resins to the powder coating and molding them, but that requires a textured mold in the case of matte finishes and have tried numerous powder coat manufacturers (some have come close at 250°F). I am desperate—are there treatments out there that match the look of powder coats with properties that are equivalent to powder coats? If so, what are they and how can I contact a possible supplier?

Since I started working with powder coatings in 1959, I should feel qualified to address your problem. Yes, I said 1959. When I joined my company, they already had two commercial powder coating lines. However, you don’t want a 20th Century powder coating answer. You need a 21st Century one, which can be provided by the “Powder Coating Clinic.” On the other hand, I would be remiss if I didn’t give you a 21st Century “Painting Clinic” answer. I don’t like to give advice, but if I were you I would just paint your products. There are paints available, that will provide finishes in various textures, to coat all your substrates.
This overview takes a look at vacuum deposition technologies as processes that may be used to create coatings that can be substituted for or enhances the properties of electroplated coatings. Initially, this work discusses trends in metal finishing and environmental regulation.
For more than forty years, academic and industrial researchers from all over the world have taken a strong interest in alternative processes for hard chromium plating using hexavalent ions. The benefits of substitute processes are obvious, as the toxic and carcinogenic aspects of hexavalent chromium are well known.
