Advantages And Disadvantages

An honest account of what powder coating does well, and where it does not.

Advantages of Powder Coatings

Greater Operating Efficiency / Lower Unit Costs

No drying or flash-off time is required. Parts can be racked closer together on conveyors and pass more quickly through the production line.

Lower Reject Rates

More parts can be coated automatically with fewer rejects because powder coating does not run, drip or sag.

High Utilization Efficiency

With proper application equipment, powder materials and efficient recovery methods, one-coat application and 95%–98% powder utilization efficiency are realizable versus an average of 60% material utilization with an electrostatic liquid system.

Production Flexibility

If more than one color is desired, color changes can be made quickly.

Minimal Training Requirements

Minimal operator training and supervision are required for a powder line. Employees prefer working with dry powder due to the lack of fumes, reduced housekeeping problems and minimum clothing contamination. A simpler coating process leads to fewer coating errors, which results in minimal scrap, reduced labor costs, and reduced operating costs.

Simplified Permit Process

The permitting process for a powder coating operation is simpler. Compliance with federal and state regulation is also easier, saving both time and money.

Disadvantages of Powder Coatings

  • Thin films difficult to obtain — 25 micron DFT is difficult to obtain.
  • Powders cannot be mixed.
  • Higher DFT affects physical properties such as impact resistance.
