Polishing Polycarbonate With Gaseous Mixture
Has anyone heard of polishing polycarbonate in a gaseous mixture? I've seen it a few times. It was a very simple process and it was self contained in a stainless steel enclosure. The operator placed the item in the tank for a few seconds and then removed it quickly. All scratches and machine marks were removed. The problem is that I don't know what the gas was? Any help.......Cuert Havens

We use a low tech approach. We fill a small oil can with a conical tip on it with WELDON #3. Place it on a hot plate set on low temp. As the liquid heats a thin column of Vapor shoots up from the can. We hold the part in the vapor flow and slowly move the part around to get a uniform finish. This vapor is NASTY! Wear a activated carbon respirator [on eBay or Amazon affil link] and goggles [on eBay or Amazon affil links]! Have great ventilation! If the liquid is heated too much it will boil up and out of the container. I once received a face full of solvent by overheating. It shot up out of the can, off the part, and in my eyes, hence the goggles. WELDON is a plastic solvent glue you can get at plastic suppliers and hobby stores.
The active ingredients are
Methyl Methacrylate Moner
We are looking for a more high tech approach. If anyone knows where we can get professional equipment please let me know.
I hope this info is helpful.
Good luck,John Niedbalec
