What is a powder color?
Color powder consists of small and dry particles of resin and pigment. This powder is applied to the surface of the product by a spray gun similar to a liquid paint spray gun. The difference between the powder paint spray gun is the presence of electrostatic charge in the resin particles. In this method, the metal product is connected to the ground and when sprayed, it attracts the particles like a magnet. As a result, the particles stick to the metal and are then baked in special industrial ovens up to 400 degrees Fahrenheit. The melted resin fuses on the surface of the metal and the result will be a uniform, thick and resistant surface.

The benefits of electrostatic powder color
Powder paint has unique advantages both in the production process and in consumption that distinguish it from other types of paint. In the following, we discuss the most important advantages of this type of paint compared to liquid paint.
Add to the above, the beauty and variety of designs and colors. In powder paints, the color gloss can be adjusted from 5 to 95%. Also, the supply of metallic, hammer, cherokee, leather-like colors, etc. has increased the variety and beauty of electrostatic painting.
Second advantage: saving cost and time
Although powder paint sprayers are more expensive than liquid paint sprayers, using powder paint is more economical in the long run. The main reason for this is the ability to recycle paint powder. In the paint powder recycling system, the colors that do not sit on the product are directed to the powder storage chamber by the air flow, and from there they go to the recycling system and can be reused. Therefore, in the mentioned color system, the loss of color is very small.
In the powder painting system, there is no need to perform actions such as underlaying and multiple painting; Rather, the desired thickness is achieved with one spray of paint and the piece enters the furnace. Therefore, by using less amount of paint and using less manpower, the desired result is achieved and space, time and costs are saved.
Third advantage: security and the environment
Solvents in liquid colors are volatile and evaporate during use. Said vapor can enter the body through the nose and mouth and cause respiratory problems or poisoning caused by inhalation of toxic vapors. This issue is ruled out due to the absence of solvent and organic compounds in the paint powder. If you use a mask, the possibility of powder entering the nose is minimized.
In the electrostatic method, the powders that are not placed on the metal surface do not enter nature; Rather, they are recycled and used again. In general, electrostatic powder paints are non-toxic and buryable and are compatible with all environmental protection standards.
