What is Electrostatic Spray?

It is the transfer of paint particles on the grounded part, by loading very low 0.7 mA and very low direct current during spraying.

There is no possibility of electric shock in the system like other power tools (drill motor etc.). When the paint comes out of the gun, electricity is charged. The paint goes to the surface of the grounded piece by following the force paths in the form of a hook. Paint particles; opposite poles are drawn on the piece according to their principle of attracting each other. However, since they are in the same pole among themselves, they push each other and provide homogeneous distribution, thus reducing the possibility of discharge and dripping to a negligible level.

What is Powder Coating?

The coating formed by melting Polymer powders after they are separated on the parts to be electrostatically coated is called powder coating.

Advantages of Powder Coating

 1) Ready to use.

There is no need to add any additives or solvents to the powder paint. It comes ready to use. Thanks to this feature, there are no errors arising from incorrectly setting the melter amounts that are very critical in traditional paint systems. In this way, it provides great savings from the mixing processes that require certain experience, space and time.

 

2) Reduces the risk of burning and shining.

Since it does not contain mixers and melters, which are considered to be highly flammable, the risk of burning and shining is too low to be compared with conventional paint. In this way, it provides great savings from insurance, fire and suction devices. For the powder paint to burn and shine, an energy application of 40MW per second is required, which is 100 times more than the energy required for the conventional paint to burn.

 

3) Cost-effective melters have no waste - no environmental pollution.
It provides great savings as it does not contain mixers and melters, which is high in oil and is directly related to oil prices, which is used in large quantities in traditional paints. Considering the fact that the substances in traditional paints fly away and not to be collected and used again during firing, these substances, which are found in high amounts in traditional paints, are wasted, and the size of the advantage of the powder paint reappears. (An average of 50% of one kg of paint is mixers and melters.) Another important problem that arises in traditional applications is that the excessively squeezed paint is thrown away. Waste and over-stuck paint in spray booths, which are mostly used in traditional methods, are mixed with water and taken out of the factory area. This is both a very polluting process and a very expensive process. Since waste and over-squeezed paint is collected and reused in powder coating applications, there is no such cost and problem.

 

4) It does not harm the health of employees.
Powder coating does not contain the vapor of mixers and melters that mix into the atmosphere, cause irritation and burns to the nose and throat, and are sometimes even apparent in hot weather. In the application of traditional dyes, some respiratory tract and skin irritation diseases are encountered in those who come in contact with the paint. Mixtures in traditional paints are both harmful to health and some melters are required for cleaning. Powder coating removes such dangers and costs. However, mask and similar protective equipment should be used to protect against the damage of powder particles.

 

5) Speeds up production.
The use of powder paint shortens the production time and speeds up the production. Because powder paint is applied in a short time like 10-15 minutes and is ready for use. In powder coating applications, as in traditional paints, there is no time loss due to the mixing of the melters and the flas-off process before entering the firing.

6) Reduces energy consumption.
Energy consumption is very low compared to traditional paint systems.

 

7) It provides a superior quality coating.
Thanks to its superior adhesion feature, it shows great resistance against corrosion, physical and chemical impacts, heat and weather conditions. Defects caused by excessive flow and dissolution of melter and mixer, which are very critical in traditional paint application, are eliminated in powder coating application.

 

8) Easy to prevent sticking of dust and metal parts.
Since adhesive melters and mixers are not used in powder coating applications, it is very unlikely that dust and metal particles within the factory will stick to the painted material. In addition, since the powder coated material enters the firing immediately, the time to stay outside is very low. In its traditional application, the material performs a quenching process before entering the furnace (flash-off), which greatly increases the adhesion rate of foreign substances on the painted parts.

 

9) False-corrupt applications can be easily corrected.
Incorrect or defective coated parts can be cleaned and re-coated by spraying compressed air before entering the furnace. In conventional paint applications, such applications are impossible.

 

10) Covers corners and shaped parts with superior quality.
The paint, which is applied electrostatically as a powder, is better adapted to shaped parts than conventional paint.

 

11) Parts can be processed after being coated with powder paint.
Thanks to the superior adhesion and impact resistance properties of powder paint, it is possible to cut and shape parts after coating.

 

12) Reduces the need for air.
Compared to traditional paint systems, the air required for air circulation and heating and ventilation of the factory area is very low, which provides great savings.

 

13) 98% paint usage.
Since the spilled powder paint can be collected and reused, it provides a 98% paint utilization rate. This feature does not accept any coating system.

 

14) Different types and colors can be applied.
It is possible to apply metallic, gilding, glossy, matt, semi-dull, orange, and powder paint in every feature.

 

15) It provides permanent control of coating thickness.
A uniform coating of the desired thickness is achieved with a single coat spray. Paint thickness can be kept under control.

 

16) It can be coated in non-metallic parts.
It is also possible to coat parts that can withstand the firing temperature, such as non-metal glass, bakelite, with powder coating. However, developing applications also allow powder coating of MDF materials.

 

17) Enamel feature in thick coatings.
When powder coating is exceeded with a coating thickness of 125 micron, it is possible to obtain a much more durable and inexpensive coating than enamel in the produced material. This type of coating is carried out with an oven at a temperature of 215 degrees, considering the enamel furnaces operating at 750-780 degrees, and the difficulty of material cleaning operation, as well as the casting defects occurring in high-grade firing, the savings and convenience brought by the powder paint once again emerge.

 

18) Provides ease of masking.
The parts that are not required to be covered are cleaned with dry brush in powder coating applications, which completely eliminates the masking cost. In some applications, it may be necessary to mask with heat resistant tapes.

 

19) It takes up more space.
It is the feature of powder paint to cover more area than wet paint. It is possible to cover an area of 14 square meters with a kilogram of powder paint at a thickness of 50-55 micron, it is not possible to cover an area of the same size as the conventional paint with the same thickness.

 

20) The installation cost of powder coating facilities is low.
Especially in automated systems, it is cheaper and cheaper than traditional paint systems.

 

21) It provides ease of storage and packaging.
There is no need for powder paint to be put in tin cans as in conventional paint. It is packaged in polyethylene (nylon) bags. This is one of the important features that affect the cost of powder paint. It is possible to store the powder paint in a closed warehouse at 250 ° C for 12 months without losing any feature. Packaging change and melter requires less storage space as the mixer does not need to be stored

 

22) Requires less worker and worker training.
Besides the many advantages of powder paint, its ease of application, the minimum level of defects during application reduces the need for skilled workers.
