Powder coating application issues

Powder falls down, doesn't adhere to the product

If you encounter this problem when applying powder coatings, perform a step-by-step check of the following parts of the powder coating application technology.

Compressed air

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

Application equipment

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

Application equipment setup

  • the voltage on the electrostatic device is set too low
  • 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 powder is wet, 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

Is there anything we can do to help?
