Powder coating of the product

The method of surface treatment with powder materials has been widely known since the middle of the last century. For products that can be heat treated, this method has become a valuable alternative to painting with conventional liquid paints and varnishes (LKM). For example, due to its undeniable advantages, powder coating is dominant in the automotive industry.

The most noticeable advantage is that the curing of the paint layer (polymerization of the substances) is very fast. It saves not only time but also materials because the powder coating is applied in one layer. Other paints – often require two to three coats and take much longer to dry.

A wide color palette of powder paint allows you to realize the most incredible building solutions. The developed painting technology creates an imitation of any surface, and also has additional protective properties.

Powder coating benefits

The price of powder paint, the service life of which is more than 15 years (on average 30-50 years), even in aggressive environments, is much cheaper than liquid coatings with a 2-year warranty. The cost of painting depends on the type of paint used, the shape and size of the product to be painted, and the method of applying the polymer material.

Also, it is resistant to weathering and does not require annual renewal.

Materials on which it can be applied:

  • glass;
  • ceramics;
  • MDF;
  • metal products that can withstand heating up to 200 C.

Application methods and cycle

Powder paints are used in large industry, in medium and small enterprises, in everyday life, it is applied in various ways:

  • tribostatic charge;
  • electrostatic spraying.

According to the laws of electrostatics, the powder is attracted to the product as it has the opposite charge – the positive one receives the powder, the product receives a negative charge.

Spraying from a spray gun is carried out on the cleaned surface so that the paint adheres evenly.

The powder in the spraying chamber is initially in suspension. Particles of paint that have not settled on the surface of the product are isolated by regeneration. Powder paint is essentially 98% waste-free. Compared with liquid, the loss of which can reach 40%.

Application process

However, the surface must first be prepared, namely: cleaned, degreased and treated with chemical compounds.

Then there is painting in the spray chamber, there should be a temperature of 170-200 C, as a result of which the paint melts, covers the painted part with a monolithic layer.

Reflow of powder paints goes through the following phases:

  • the powder becomes viscous;
  • a monolithic layer is formed from the fused powder particles.
