Powder coating

Process of applying powders to the surface of pieces to make them resistant to various external agents. By inducing electrostatic charges, the powder is directed towards the piece, reducing the particles suspended in the air to a minimum. The coating powders vary considerably according to the results to be obtained. They are generally based on epoxy, acrylic, polyester, polyurethane or nylon.

Filtration must therefore take into account the following specific parameters:

  • air with medium-low dust load of medium-fine particle size
  • presence of electric and electrostatic charges, risk of fire/explosion
  • based on the paint: possible presence of special additives that modify the adherence to the surfaces; nanotreatments; water repellency; acrylic fillers etc.
