Powder coating

 

Electrostatic painting or lacquering is a process that aims to coat iron, aluminum, copper or other metals with a color thermosetting polymer film (polyester powder). There is a huge variety of plain colors on the market and some also have texture and color effects. When a piece is painted, the paint receives an electrical charge opposite to that of the piece, which causes the paint to stick to the material evenly in areas of difficult access. The powder-coated part goes through the curing process, in a heated oven with temperatures ranging between 180 ° C and 220 ° C, for 10 to 20 minutes. Here the paint molecules bond, forming a rigid and uniform film. This type of paint guarantees better adhesion and economy in the paint, as well as less application and curing time, providing a quick availability of the part for handling and use.

In the image we see hooks, which support the parts submerged in a cleaning bath. The purpose of this bath is to better adhere the film to the metal.
