Difference between wet painting and powder coating of machine frames, with special consideration of ESD coating

In wet painting, liquid paint is applied to the surface and then dried. This process often requires several coats and drying times.

In powder coating, on the other hand, a powder is applied to the surface and then melted by heating. This results in a thicker and more even coating. Powder coating is generally more durable and environmentally friendly, while wet painting is often easier, faster and more cost-effective. Wet painting is also not limited by the size of the component, whereas powder coating is dependent on the size of the coating equipment.

ESD powder coating is a special type of powder coating that has been developed to allow electrostatic discharge. By adding conductive materials such as metal particles or carbon fibres to the powder, a coating is created that can dissipate electrical charges. This is particularly important in areas where sensitive electronic devices must be protected from electrostatic damage. ESD powder coating is often used in the electronics industry, mechanical engineering and medical technology.

We can measure the layer thickness and thus the conductivity. On request, we can also provide you with the accompanying measurement report for electrical resistance and electrostatic conductivity in addition to the ESD coating.
