Understanding the working of industrial powder coating

Powder coating is basically an alternative to the conventional wet painting, which is used for automotive and other metal parts. It involves a process in which a layer of specially treated solid pigment is which is in a dry powder form is applied to a surface. This surface is then further heated and undergoes a chemical reaction as and when the temperature rises. As a result of this reaction the powder melts and hardens into a single solid surface matching the outlines of the items to which it is applied. There are many advantages to powder coating when compared with wet painting. Apart from being cheaper and ecofriendly, it also creates a much durable surface that is less likely to scratch and chip and is also tougher and stronger when compared with the conventional wet paint. This method is also being widely used in automotive industry for bumpers, wheels and also for final finishing.

Industrial powder coating is also taking an extensive place in various industrial companies. The powder is immediately is immediately ready for use which necessarily saves a lot of time. Also, during the entire application process, there is also less powder wastage which is economically convenient for the companies. Moreover, there are significantly reduced health hazards in case of exposure of operators, which is in compliance with the purpose of health consciousness and lower capital investment costs. These are some of the many benefits that you can get while using industrial powder coating for various needs of your industry.

Different companies and business prefer powder coating system due to the quality finish that it creates. The finish is absolutely scratch-free and does not create bubbles and drips. More and more users prefer powder coating system because it is durable and a smarter choice than using the regular solvent based coating technique. However, before an item can be coated, it must be cleaned and kept free from any dirt, grease or oil. The spraying mechanism which is similar to a paint gun is called a corona gun. It is a simple air-powdered device with a hopper containing the powdered pigment in the form of a thermoset polymer. As the powder is fired out from the nozzle, the corona gun imparts a mild negative charge. This gives an understanding that the powder and the item have an opposite charge and that they will attract each other and the powder will naturally cling to the surface immediately upon contact.
