Differences between Powder Coating and Wet Paint

 

To understand why powder coating’s more advantageous than wet paint, it’s important to first understand the process. Powder coating is the electrostatic application of organic powder to metal parts requiring protective or decorative coating. The powder is cured by heating or baking, resulting in a hard, continuous coating. Benefits of Powder Coating below:
  • Contains no volatile organic compounds (VOCs)
  • Does not contain solvents
  • Up to 95% utilization of raw material
  • Curing takes 20 minutes, whatever the weather
  • Does not produce hazardous waste
  • Controlled application conditions

 

Liquid paint is dispensed in a fine spray. Some liquid paints are air dried, while others are placed in a curing oven.It is normal for both powder coating and liquid paint to include a primer and a color coat; however liquid paint may also include multiple color coats and a clear top coat. Benefits of Wet Paint below:

  • Contains up to 70% solvent
  • Contains ozone depleting VOCs
  • Curing depends on atmospheric conditions and may take days
  • Disposed as a hazardous waste
  • Potentially uncontrolled application with hazardous waste
  • Uncontrolled over-spray, spillage and air pollution

 

Many businesses now employ Symach technology as a high speed, energy efficient drying method.
