Pulverimaalausta

Pulverimaalausta, also known as powder coating, is a type of coating that is applied as a free-flowing, dry powder. The process involves three main steps: preparation, application, and curing. The preparation step involves cleaning the substrate to remove any contaminants, followed by application of an electrostatic charge. The powder coating is then applied using an electrostatic spray gun, which ensures even coverage. In the curing step, the coated object is placed in an oven, where the powder melts and flows to form a continuous film. This film is then cured to form a hard, durable coating.

Powder coating offers several advantages over traditional liquid coatings. It provides excellent corrosion resistance, as the powder forms a seamless, uniform film. It also offers a wide range of color and finish options, and the process is environmentally friendly as it does not require the use of solvents. Additionally, powder coating can be applied to a variety of substrates, including metals, plastics, and composites.

The powder coating process is widely used in industries such as automotive, aerospace, and electronics, where durability and resistance to environmental factors are crucial. It is also used in the production of consumer goods, such as furniture and appliances, to enhance their appearance and longevity.
