High overspray during application

Compressed air

• air transport pressures set too high (blowing off the powder)

Application equipment

• improper application method
• worn electrostatic parts (CORONA):
  • the cascade fails to charge
  • the electrode is demaged
  • electrode O-ring - no current is conducted to the electrode
• worn TRIBO parts:
  • poorly grounded painting device
  • damaged charging hose
  • the powder coating gun fails to charge

Application equipment setup

• the voltage on the electrostatic device is set too high
• the powder coating gun is too close to the sprayed surface during application (blowing off the powder)

Paint (powder coating)

• improper powder for the given application: TRIBO / electrostatics (CORONA)
• the wet powder fails to hold the charge
• the powder is too fine:
  • the recycled material content is too high
  • too fine from production

Part and its hanging

• insufficiently grounded product
