Powder Coating
Powder coating is a modern and environmentally friendly process for coating metallic surfaces. In this process, an electrically conductive workpiece is coated with a special powder coating. This powder coating consists of finely ground plastic particles that contain resins, pigments and hardeners, among other things. The particles are electrostatically charged using a special spraying process and sprayed onto the surface of the workpiece. Due to the electrostatic charge, the powder adheres evenly to the object. The coated workpiece is then heated to a certain temperature in an oven. In this so-called stoving process, the powder melts, forms an even layer and cross-links to form a resistant, smooth or textured surface.
Powder coating offers numerous advantages over other coating processes. It is solvent-free and therefore particularly environmentally friendly. Powder coating is also characterized by its high mechanical resistance. It reliably protects the treated surfaces against corrosion, chemicals, weathering and wear and tear. It also offers many visual design options, as a wide range of colors, gloss levels and surface textures are available. Typical areas of application include vehicle construction, architecture, mechanical and plant engineering as well as the furniture and household appliance sector. Where durability, environmental awareness and a high-quality appearance are required, powder coating has established itself as a proven technology.
