Powder coating can be removed by a burning off approach, wherein pieces are set into a large significant-temperature oven with temperatures typically achieving an air temperature of 300–450 °C.
Article-Fusing: The last period of fluidized mattress powder coating is the publish-fusing course of action. Soon after any surplus powder drips from the product or service, it is actually transferred to an oven established in a decreased temperature for curing. Importantly, the publish-heat temperature needs to be lower than that from the Preliminary preheating oven.
