Frequently Asked Questions
Powder coating is a completely dry coating system. It consists of electrically loaded ground resin, pigment and other raw material particles and is sprayed on objects to be painted.
Electrostatic powder coating is a solvent-free surface coating method. The coating material is very fine powder coating particles that make up the final layer of paint. Powder paint is discarded through special paint guns in the paint cabinet. When passing through the gun, electrostatically loaded powder particles stick to the material to be painted in the cabin and the coating process takes place.
In order to get excellent results from the painting process, the part to be painted must be cleaned and pre-processed. There are several methods used in part cleaning.Acidek cleaners work well for inorganic impurities, while alkaline cleaners are better suited to organic impurities. Oil-consuming chemicals are used for other organic impurities.
It is performed by means of electrostatic pistol. Two types of handguns, the corona and the tribo, are available for this purpose. In a Corona-type gun, the powder is charged electrostatically negative thanks to a high-voltage electrode located at the end of the gun as it leaves the gun. Because the part to be painted is grounded, the paint that is electrostatically loaded easily adheres to the part.However, sometimes the Faraday effect can occur on very indented and protruding parts and the entry of dust into the pit areas can be problematic. Tribo-type pistols are used in these cases. In this type of gun, the paint is loaded with a positive charge with only friction without applying high voltage.
Powder paint applied part is put in ovens. At this stage the piece is exposed to the time and temperature given in the properties of the paint. At this temperature, the paint first dissolves and cures after forming a flat floor. After the part is removed from the oven at the end of this period, the painting process is completed. Powder coating products usually cure at 200 degrees in 10 minutes. However, the 10-minute period mentioned here is started after the track reaches 200 degrees.
