Electrostatic powder spraying

Electrostatic powder spraying is a modern coating process that is widely used in industrial surface technology. It uses electrostatic forces to transfer fine powder onto a surface to be coated and create an even, adhesive coating.

The process begins by charging the powder in a container. The particles of the powder receive an electrostatic charge, which causes them to repel each other and simultaneously attract towards the grounded or oppositely charged surface. The surface to be coated is usually earthed during electrostatic powder spraying. This causes the charged powder to adhere evenly and efficiently to the surface due to the electrostatic attraction. The electrostatic effect makes it possible to evenly coat hard-to-reach areas and corners.

After the powder has been applied to the surface, it is baked by heating in an oven or by UV radiation to form a durable, protective coating. This melting process ensures that the powder melts into a solid, even layer.

Electrostatic powder spraying is used in various industries, including automotive manufacturing, furniture, metalworking and architecture. Not only does it provide an efficient way to coat surfaces, it is also environmentally friendly as excess powder can often be collected and reused. This process enables the creation of high-quality, long-lasting coatings with a variety of colors and surface effects.
