OVERVIEW OF POWDER PAINT

Paint is an organic coating material that contains coloring agents in its composition which are called pigments. It has a history of nearly 40 thousand years. People living in the caves used raw paints to express their lives with figures, and these figures have reached us today.

The use of paints and coatings as a true industry component started in the late 1940s and early 1950s. The German scientist Dr.  Erwin Gemmer developed the fluidized-bed process in which powder coatings are fixed with heat. Between 1958 and 1965, all functional powder coatings with a film thickness of 150 microns to 500 microns in general were processed by fluidized-bed application. The high film thickness and the development of electrostatic powder coating technology in the USA between 1962 and 1964 reduced the interest in fluidized bed application.

Electrostatic powder paints are generally applied by spraying technique. The main feature of this technique is that the material to be coated with powder is grounded and the powder particles are electrically charged. As a result, an electrostatic attraction occurs between the powder paint and the material, which ensures that a sufficient thickness of film is formed on the surface of the material and that the powder paint melts and adheres to the surface of the material.

The use of powder painting increased with the introduction of resins developed between 1966 and 1973 into commercial use. Electrostatic powder paint, which has been on the rise since the early 1970s, appears to be the industry's most preferred technique after the 1980s.

At this point, electrostatic powder painting is preferred in automotive parts, home appliances, durable consumer goods, furniture metal parts, railway vehicles, architectural structures and many more.
