Powder coating is a way of surface protection in case of corrosion and damage. It is essential to control the humidity of the coating room into a relative low level to make the spray environment ideal for the powder particles painting to the surface. That is because the powder particles are hygroscopic, which will contain different degrees of water. Installing a dehumidification system
, will also offer a fewer dust room, making the spray work more convenient. Thus, the agglomerates will be decreased, transfer efficiencies increased. As a result, human labor and cost are saved.
