Electrostatic painting for small parts

Electrostatic painting for small parts is a highly effective coating method, particularly used in the industrial, automotive, metal furniture, and decorative sectors. This technique relies on the application of an electrostatically charged powder coating, which is then baked on.

How does it work?

1. Part Preparation: Cleaning, degreasing, and sandblasting if necessary to ensure good adhesion.

2. Powder Application: Powder paint (usually based on polyester, epoxy, or hybrid resins) is sprayed using an electrostatic gun.

   • The powder particles are electrically charged.

   • The part to be painted is placed earth, thus attracting the powder evenly, even into corners.

3. Firing: The part is placed in a high-temperature oven (160–200°C), where the powder melts, gels, and then polymerizes to form a solid coating.

Benefits for small parts

• Consistent application even on complex shapes.

• Less product loss: thanks to the recovery of undeposited powder.

• Excellent performance: resistant to impact, corrosion, UV rays, and chemicals.

• Precise finish: glossy, matte, textured, or metallic as needed.

• Eco-friendly: solvent-free and VOC-free (volatile organic compounds).
