Unlike the conventional paint coating, powder coating is done using a dry powder. Also, powder coatings do not make use of any solvents as is the case for liquid paint coatings. To make the powder coat to flow over the surface of the object being coated, a curing process of the powder has to be induced by the use of heat. Generally, powder coating has a number of benefits over the conventional liquid paint coating as we shall discuss below.
The first benefit for using powder coatings is that there is less environment pollution due to the lack of volatile organic compounds which the liquid paints are so rich of. The volatile organic components have a great potential for degradation of the environment due to their pollutant nature. When less pollutants are available in the coating, it implies that the environment is less polluted and therefore safe for habitation. Moreover, for industries handling powder coatings, there is no need to worry of dealing with volatile organic components and this is a great financial relief for them. This gives these industries the chance to concentrate their resources on only what is necessary for them.
Secondly, powder coatings are able to give a tougher and a thicker coating than the conventional paint coatings. The advantage of having a thick and a tough coat is that the object being coated is protected from external factors that could lead to it wearing out easily. Furthermore, a tougher coating rarely requires any replacements to be done on it and this reduces the costs of production. The appearance of the coated object is also maintained since there is less abrasions to be done on it since no coat replacements are required.
The other advantage of powder coating is that it makes it easy for designers to come up with more design patterns as opposed to the case of liquid painting. This versatility of the powder coating stretched the creativity of the designers to come up with unique patterns that serve to satisfy the more needs of the clientele.
Lastly, as opposed to the liquid paint coatings, powder coatings do not require much curing process and time. In the case of the liquid paints, the curing process has to be done by the use of natural elements such as cold air flowing over the coated object and this process is unregulated and slow. The purpose of the dry air is to force the paint coat to dry and stick to the coated object. On the other hand, for powder coating, the curing process can be induced and can therefore be controlled by varying the curing parameters such as heat and this significantly reduces production time.
