As I have learned so far, powder coating custom color matches are more difficult unless the production volume is high. My volume is low, around 1000 parts per year at 5X7X8 inches per part. Also I understand that the texture might be a problem. There are semi-textured powders in high gloss and in low to mid gloss. They are not exactly the surface profile of Polane, but they have been used to replace it.
Many colors are available.
I am looking for a powder coating for plastics. My company is interested in a textured powder to match aluminum parts we are using. I have an injection molded smooth part, to allow for chroming, that I need to texture for some applications. Bob, Herberts-O'Brien is now DuPont Powder Coatings and does have UV curable systems that may work for your need. I want to post a question or inquiry of my own.
