The benefits of industrial powder coating

Powder coat is an alternative to using conventional wet paints for automotive and other metal parts. it basically involves a process in which a layer of specially treated solid pigment in the form of dry powder is applied to the surface to be powder coated and is then heated by undergoing a chemical reaction as and when its temperature rises. As a result of this chemical reaction, the powder melts and then hardens into a solid single surface matching the contours of the item to which it is applied. There are numerous advantages of powder coating over other conventional paints. Apart from being cheaper and eco-friendly, powder coating also creates a much more durable surface, which is far likely to scratch and chip. 

Applications of powder coating

There are a number of applications of powder coating, however, before an item is prepared for being coated, it is essential to clean the surface and make it free from grease, dirt or oil from the hands. Once powder coating is performed on the required surface, it should be brushed in order to keep it free from grit or dried remaining moisture. The item is then connected to a small electrode imparting mild, positive electrical charge. Spraying of paint on the surface is usually done with a spray gun, which is also called a Corona gun. This gun is usually described as air powdered device with a hopper that contains the powdered pigment in the form of thermoset polymer. A mild negative electric charge is imparted from the powder gun when the powder is fired out from the nozzle. This simply states that the powder and the item that is to be powder coated hold opposite charge. These opposite charges attract each other and hence the powder naturally clings to the surface immediately upon contact. 

Industrial powder coating

There are various equipment that are used for industrial powder coating. Some of them are aerospace oven, industrial walk-in paint drying batch oven, continuous conveyer oven and industrial powder coating oven. This coating equipment can be helpful in powder coating industrial surfaces in a cheaper and healthier way. There is no special preparation needed in the process since the paint is not required to be mixed with a solvent or any other substance that helps in saving unnecessary time and effort. Additionally the waste product that is created after powder coating is comparatively quite less.
