Powder coating and coloring, why do we use specifically it

Nowadays Powder coating of metal is widely used all over the world because it permits get the surface of excellent quality. It is strong, attractive, durable, it resists corrosion and maintains aesthetic appearance for a long time.

The advantages of powder coating are the following:

• Environmental friendliness. This covering is toxins free, do not contain heavy metals that are health hazard. It can be used by children and people with allergy without any consequences.
• Bruise resistance. The coat of such painting remains the same while deformation of the surface. This makes it more safe in comparison with usual oil paintings. In addition, all objects undergo the procedure of galvanization, that also increase their operating life.
• Life duration and width of application. The powder coating is dozen times more solid and durable that covering with usual painting. Such type of technology is eminently suitable for painting of aluminum shapes, forged products, galvanized surfaces. That's why it is used not only for outdoor furniture but also in construction, farm machine industry, automobile construction, architecture and in production of domestic appliances.

During the process of covering, metal comes through several operating steps:

1. Metal degreasing and treatment with special composition – parkerising to increase endurance and resistance to corrosion.
2. Equable dispersal of painting from the special equipment in powder spray booth.
3. Heat treatment – dispersed powder fluxes equably and composes equal layer, that penetrates in all interstices and metal structures.
4. Cross-linking of products is made in cooling zone. After thermal booth the temperature is going down that provides solidification of the covering.
