jauhepäällinen

Jauhepäällinen is a Finnish term that translates to "powder-coated" or "powder-finished." It refers to a method of applying a dry finishing powder electrostatically to a surface, which is then cured under heat. This process creates a durable and attractive coating.

The powder used in jauhepäällinen is typically a thermoplastic or thermoset polymer. Common types include polyesters, epoxies, and hybrids of the two. These powders are finely ground and contain pigments for color and other additives to achieve desired properties like UV resistance or flexibility.

The application process involves cleaning the substrate, often metal, thoroughly. The part is then grounded, and the powder is applied using an electrostatic spray gun. The charged powder particles are attracted to the grounded object, creating a uniform layer. After application, the part is heated in an oven, causing the powder to melt, flow, and fuse into a continuous, smooth finish.

Jauhepäällinen is widely used for its advantages over traditional liquid coatings. It is environmentally friendly, as it contains no volatile organic compounds (VOCs). The coating is also highly resistant to chipping, scratching, fading, and corrosion. This makes it ideal for a variety of applications, including automotive parts, appliances, furniture, architectural elements, and industrial equipment. The resulting finish can range from matte to high gloss and is available in a vast array of colors and textures.
