Hey mate!
Here is your answer !
Powder coating is a type of coating that is applied as a free-flowing, dry powder. The main difference between a conventional liquid paint and a powder coating is that the powder coating does not require a solvent to keep the binder and filler parts in coating and is then cured under heat to allow it to flow and form a "skin". The powder may be a thermoplastic or a thermoset polymer. It is usually used to create a hard finish that is tougher than conventional paint.
Hope it helps ☺️!
Have a great day !

1. Powder coatings contain no solvents and release little or no amount of Volatile Organic Compounds (VOC) into the atmosphere. Thus, there is no need for finishers to buy costly pollution control equipment. Companies can comply more easily and economically with the regulations of the U.S. Environmental Protection Agency.[2]
2.Powder coatings can produce much thicker coatings than conventional liquid coatings without running or sagging.
3.Powder coated items generally have fewer appearance differences than liquid coated items between horizontally coated surfaces and vertically coated surfaces.
4.A wide range of speciality effects are easily accomplished using powder coatings that would be impossible to achieve with other coating processes.[3]
5.Curing time is significantly faster with powder coating than with liquid coating.[4]
6. The polymer granules are mixed with hardener, .pigments and other powder ingredients in an industrial mixer, such as a turbomixer
7.The mixture is heated in an extruder
8.The extruded mixture is rolled flat, cooled and broken into small chips
9.The chips are milled and sieved to make a fine powder
10.There are two main categories of powder coating: thermosets and thermoplastics. The thermosetting variety incorporates a cross-linker into the formulation. When the powder is baked, it reacts with other chemical groups in the powder to polymerize, improving the performance properties. The thermoplastic variety does not undergo any additional actions during the baking process as it flows to form the final coating.
The most common polymers used are: polyester, polyurethane, polyester-epoxy (known as hybrid), straight epoxy (fusion bonded epoxy) and acrylics.[clarification needed]
