Powder coating

During the fluidized bed coating, a mesh is dipped in an adhesive bath, dried and pre-heated. It passes into a bath with fluidized PVC or another polymer powder which acts like a liquid when air is forced through  the powder bed. This covers the wire surface with powder that melts on the substrate due to the preheating of the substrate.
This is followed by after-curing or after-fusion of the polymer, and water cooling.
Panels and post objects undergo a more complex electrostatic powder coating process that starts with up to 10 stages of pre-treatment ( zinc-phosphatation). Electrostatic guns spray charged powder particles on the objects which are connected to the earth. The polyester powder is then cured intensively to reach his optimal properties.
