Powder coatings do not contain organic solvents, which can avoid environmental pollution caused by organic solvents, fire hazards, waste of organic solvents and harm to human health; powder coatings do not contain water, and can also avoid water pollution problems like waterborne coatings. .
The biggest feature of powder coatings is that the sprayed coatings can be recycled and used effectively. If the recovery efficiency of the recycling equipment is high, the utilization rate of the powder coating can reach 99%.
The coating production of powder coatings is highly efficient, and one coating can achieve a thickness of several to ten coatings of solvent-based or water-based coatings.
The coating of powder coatings is not affected by temperature and season. It does not require very skilled coating technology, it is easy to master the coating technology, and it is easy to achieve automatic assembly line coating.
Disadvantage
The production and coating of powder coatings requires special equipment and the production and coating equipment for solvent and waterborne coatings cannot be used directly.
In the production and coating process of powder coatings, changing the color and variety of coatings is more troublesome than solvent-based and water-based coatings.
Powder coatings are not suitable for thin coatings and are only suitable for thick coatings.
Powder coatings have high baking temperatures, most of which are above 180 °C. Most of the varieties except UV-curable powder coatings are not suitable for heat-sensitive objects such as plastics, wood and paper with poor heat resistance.
Powder coatings are considered to be high-efficiency, excellent cell performance, eco-friendly and economical 4E coatings, with the fastest growth among coatings.
