What is Electrostatic Powder Coating?
Electrostatic powder paint, which is very successful and environmentally friendly when compared to traditional painting methods, is a solvent-free painting method. The electrostatic powder coating method, which is quite successful, is realized by applying very small powder paint particles charged with negative (-) electricity to metal surfaces.
99.9% of the paint applied to the surface during the application fully adheres to the floor.
The answer to the question of what is electrostatic powder paint is the painting method, which is formed as a result of the attraction of the paint particles at opposite poles and the floor to be painted. The metal floor covered with powder paint is heated in ovens between 180 and 200 degrees so that the powder paint adheres to the surface completely. At this stage, all the paint particles and the floor are intertwined and the painting process is completed.
NOTE: The grounding of the metal surface must be very good for the electrostatic powder coating process to be successful. The better the grounding of the metal surface is done, the higher the adhesion rate of the paint to the floor.
So let’s examine how electrostatic powder paint is made.
How is electrostatic powder paint made?
The painting process is carried out with the help of the guns in the paint booths specially created for electrostatic powder coating. The powder paints loaded on the guns are electrostatically charged and form opposite poles with the metal surface, which allows the paint to adhere to the floor easily.
Powder paint particles, which adhere to the ground by forming opposite poles, also form positive poles among themselves and thus spread on the surface homogeneously. This is the secret of success in this method.
The metal surface, which is grounded very well, integrates with the powder paint and is baked in ovens at 200 degrees, allowing the paint to adhere to the floor.
There is no possibility of electric shock in the electrostatic powder coating method. Because this process is carried out by loading a very low current.
It should be noted that the electrostatic powder coating method is environmentally friendly as well as works with a zero-waste logic. Because in this painting method, the paints thrown on the surface in excess are collected in the paint recovery system, preventing the material from being wasted, as well as preventing the spread of waste material to the environment.
Therefore, when compared with traditional painting methods, electrostatic powder painting method;
- Ecofriendly
- Working with zero-waste logic
- Successful
- Can be applied in different colors
- harmless to health
- Glossy surface finish
- Economic
- Sustainable
It is a painting method.
You can get more information by watching the video on how to make electrostatic powder paint below.
We mentioned that electrostatic powder paint is used on metal surfaces. Well, let’s examine where else this painting method is used.
Where is electrostatic powder paint used?
Since the powder coating method is very successful, it has the success of being integrated into many different sectors. These;
- Steel door manufacturing
- bicycle production
- Production of playground toys
- Steel shelf manufacturing
- white goods industry
- lighting industry
- Metal furniture manufacturing
- Manufacture of agricultural vehicles
- Electrical panel manufacturing
- Panel radiator manufacturing
- machinery industry
- Aluminum industry
- automotive industry
The sectors mentioned above are the sectors where electrostatic powder paint is used the most and is successful. It is natural for such an environmentally friendly and successful method to be used so widely.
With the electrostatic powder coating method, you can also obtain very successful surface coatings and make an economical investment.
What are the advantages of electrostatic powder coating?
The advantages of the powder coating method, which is so successful, are also quite high.
- It is economical.
In the electrostatic powder painting method, where the waste management is done very well, pre-painting is not done. Because this step is not necessary. In addition, excess paint is collected in the paint booth and reused, which paves the way for low-cost production. It is an economically special dyeing method since there are no preparation steps such as pre-mixing.
- 99.9% Successful Perfect-Surface Coating
Thanks to the attraction of opposite poles in the powder coating method, a successful coating process is achieved with the perfect adhesion of the powder paint to the floor. In addition, the product formed after the dyeing phase;
- corrosion-resistant
- abrasion resistant
- Resistant to chemical reactions
- Resistant to hard impacts
It is happening. It should come as no surprise that the use of a method that is both easily applicable and durable is widespread.
- The Color Scale is quite wide.
All RAL colors can be used in the electrostatic powder coating method. In addition, color change can be performed easily in this method. After cleaning the paint booth and guns with compressed air, the paint on the surface is wiped off and a new one can be made.
- It is an environmentally friendly dyeing method.
The electrostatic powder coating method is a very environmentally friendly painting method. No chemicals are used during painting, and solvent-containing solvents are not used either. We can say that the painter will perform this operation by wearing only a mask.
In addition, we can say that it is a sustainable dyeing method since it does not create waste paint.
Every environmentally friendly and sustainable method is ready to be among the most successful applications of the future world. Therefore, the usage area of ​​the electrostatic powder coating method is getting more and more widespread day by day and it should become widespread.
- It can adapt to automation.
- It has a low maintenance cost.
- It provides great benefits to large facilities with mass production.
- No mixing air device is required.
- It is a reversible paint method.
As you can see, it would be quite correct to say that this method, which is quite successful when compared to traditional dyeing methods, is a profitable method for its investors.
Methods of electrostatic powder coating
The electrostatic powder coating method, which can be applied in 2 different ways, can be done by using Ionization and Electro-kinetic methods.
- Ionization (CORONA) Method
It is the classical powder coating method that is carried out by charging electricity into the powder coating gun. This method, which can be applied to the grounded surface very easily, is carried out by electrically charging the ions sent to the gun with high voltage.
It allows the powder paint, also known as thermoset paint, to adhere successfully to the floor.
- Tribo (Electro-Kinetic) Method
Tribo, which is a paint gun, is a gun made using Teflon material. In this method, the aim is to create kinetic energy by rubbing between the air and the paint, and it is aimed to cling to each other. The dyeing process is carried out by the method of combining two different substances, which tend to gain and lose electrons.
As you can see, electrostatic powder coating is very advantageous and we can say that it is the painting method of the future. Therefore, if you would like to have electrostatic powder coating done, you can contact our expert and experienced company Aktif Lazer, and take advantage of advantageous price offers.
