Electrostatic painting

Do you know what electro static painting is? Prose uses this application when it works on updating or refurbishing furniture.  Here is a bit about what this is:

Electrostatic coating is a manufacturing process that employs charged particles to more efficiently paint a workpiece. Paint, in the form of either powdered particles or atomized liquid, is initially projected towards a conductive workpiece using normal spraying methods, and is then accelerated toward the work piece by a powerful electrostatic charge.[1]
An addition to the electrostatic coating (or e-coating) process is dipping electrically conductive parts into a tank of paint that is then electrostatically charged. The ionic bond of the paint to the metal creates the paint coating, in which its thickness is directly proportional to the length of time the parts are left in the tank and the time the charge remains active. Once the parts are removed from the paint tank, they are rinsed off to remove any residual paint that is not ionically bonded, leaving a thin film of electrostatically bonded paint on the surface of the part.

Process characteristics

  • Uses a high voltage electrostatic charge which is applied to both the workpiece and the sprayer mechanism
  • Uses 95% of sprayed paint due to reduced over-spray and better wrap-around
  • Paint materials can be either powdered or liquid
  • Process can be either automatic or manual
  • Workpieces must be conductive
  • Workpieces are usually baked after coated
  • The baked on paint adheres extremely well and is difficult to remove without aggressive means of removal.
Prose uses these techniques and more to produce the best quality look and feel. Call Lucas at (913) 441-4499for more details.
