1. Electrostatic Spraying:

   • The spray gun generates a high voltage to create an electrostatic field, charging the powder coating particles.
   • The charged powder particles are attracted to the grounded workpiece surface, achieving uniform coverage of the coating.

2. Coating Process:

   • The powder coating is expelled from the spray gun, forming a mist, and the powder particles are quickly adhered to the workpiece due to electrostatic attraction.
   • The electrostatic force allows for a thicker and more uniform coating on the surface of the workpiece.

3. Curing:

   • After the coating is complete, the workpiece is placed in an oven for heating, where the powder coating melts and cures at high temperatures, forming a hard and wear-resistant layer.

Features

• Environmentally Friendly: Electrostatic powder coating does not use solvents, reducing the emission of volatile organic compounds (VOCs).
• Uniform Coating: The electrostatic spraying process achieves consistent coating thickness, minimizing material waste.
• Strong Adhesion: The electrostatic effect enhances the adhesion of the powder to the surface of the workpiece, improving the durability of the coating.
• Variety: Applicable to various materials (such as steel and aluminum alloys), and the powder coatings come in diverse colors and finishes.

Application Fields

Electrostatic powder coating is widely used in the automotive, appliance, furniture, and construction industries, suitable for surface coating of various metal products.
