What temperature is the oven for powder coating?
350 to 400 degrees Fahrenheit
The curing process for powder coating is normally done in a special oven; the coating has to be exposed to a temperature range of 350 to 400 degrees Fahrenheit (160 to 210 degrees Celsius) for 20 minutes. When melting the more common thermosetting powder, it bonds chemically to form a hard, permanent layer of paint.
