I've read up a little on powdercoating, and it sounds like it would be real handy to be able to do myself. I know a few of you folks have done it, so I wanted to ask : 1) How bad is the smell (while curing) ? I'm thinking of doing smaller parts in a small electric oven indoors, but under a dedicated vent hood. Sound reasonable ? 2) What does it smell like ? Burning plastic ? 3) Does the smell really linger afterwards, or does it go away with decent air circulation ? 4) How satisfied are you with your results ? Did it take much practice before parts came out looking acceptable ? 5) I'm planning (if I do this) to get the Chicago Electric (Harbor Freight) unit. I know their stuff is crap, but don't plan on using it all that often. Anybody have good/bad experiences with this unit ? |

Time at temperature is really up to the powder manufacturer spec sheet.
Different powders take different temps to properly crosslink. Different parts (more or less dense) take more time to get to temperature. You can undercure powder and it never will obtain full hardness or gloss. You can overcure powder and it can slightly change color or in really bad cases it can change colors drastically (and not for the good). Eastwood also sells a bunch of different powders and coating equipment for the hobbiest. Since we sell the equipment, we usually get free samples from powder suppliers. If you know the supplier, you can obtain the spec sheet from them for your specific powder (including curing schedules). Powder provides a quick durable surface, but I still prefer spraying liquid paints. |
