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
