In our daily life, we often see the powder in our daily life, such as the powder in the building materials and equipment.

Today we would like to introduce the characteristics of powder coatings, because of these characteristics of powder coatings, powder coatings are more and more widely used.

characteristics of powder coatings 1:

It is that the utilization rate of liquid paint is only 50% - 60%. While the powder coating powder rate is about 70% - 80% (affected by the shape of the workpiece and other factors), the rest of the powder can be recycled again, the utilization rate is 90% - 98%.

characteristics of powder coatings 2:

It is that 30% - 50% diluent must be added in the construction process of liquid paint coating, and the role of these diluents is only to adjust the viscosity, not the necessary component of curing film, which evaporates in the process of recycling. It not only pollutes the environment, but also makes a lot of idle work, wastes raw materials and raises production cost; in the process of powder coating construction, this kind of diluent is not needed at all.

characteristics of powder coatings 3:

It is that the thickness of liquid paint is generally 15-30 μ m, while the powder coating can reach 60-150 μ m at one time, which can reduce labor intensity and is suitable for automatic production line operation.

characteristics of powder coatings 4:

Powder coatings cured appearance of high degree of fullness, soft color, so that paint liquid coating after curing the appearance of the effect beyond dust.

characteristics of powder coatings 5:

Powder coating does not contain solvent, so it is not easy to form pinholes and bubbles in the curing process, while liquid coatings are easy to form pinholes and bubbles due to the existence of volatile solvents and diluents.

characteristics of powder coatings 6:

 Powder coating is easy to transport, will not leak and volatilize, while liquid coating transportation is very inconvenient, easy to leak and volatilize, and may even burn and explode.

characteristics of powder coatings 7:

Good anti-corrosion and decoration, low production cost, and no comparable liquid paint
