Pulverimaalauksia

Pulverimaalauksia, commonly known as powder coating, is a dry finishing process that uses finely ground particles of pigment and resin suspended in the air and applied electrostatically to the surface of an object. The charged powder adheres to the object, which is then cured under heat in an oven. This heat causes the powder to melt, flow, and form a smooth, continuous, and durable finish.

The process begins with the object being thoroughly cleaned and pretreated to remove any dirt, oil, or rust. This ensures optimal adhesion of the powder coating. The object is then electrically grounded, and the powder is applied using a spray gun that imparts an electrostatic charge to the powder particles. As the particles are sprayed, they are attracted to the grounded object, forming a uniform layer.

After application, the object is placed in a curing oven. The temperature and duration of the curing process depend on the type of powder coating used. During curing, the powder melts and fuses into a protective layer that is significantly more durable than conventional liquid paints. Powder coatings are known for their resistance to chipping, scratching, fading, and corrosion. They are available in a vast array of colors and finishes, including matte, gloss, metallic, and textured options. This makes pulverimaalauksia a popular choice for a wide range of applications, from automotive parts and household appliances to architectural elements and industrial equipment.
