What exactly is Powder Coating?
There are two types: Thermoplastic Powder and Thermoset Polymer. Thermoplastic Powder is generally applied with a fluidized bed process. First, the part is heated to a temperature above the melting point of the powder. Then, the heated part is dipped into a pool of free-flowing powder. As the part is dipped the powder around it melts and forms a smooth homogenous bond coating the surface. It can also be applied with an electrostatic spray process, where the part is heated to a temperature above the melting point of the powder, and then the powder is sprayed onto the heated part. The powder, upon contact, will melt onto the part and form a strong coating.
