As opposed to paint coating, powder coating is a form of coating that is achieved by the use of a dry powder. Whereas the pain coating requires the use of a solvent to dissolve the paint, powder coating doesn’t require any solvent and this implies that the coating is fully achieved by the use of a dry powder. The use of heat is mandatory for powder coating since the heat causes the dry powder to flow over the surface of the object being coated. 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. Due to their potential for polluting the environment, volatile organic components should rarely be used. With the presence of less contaminants in the coatings, there is a chance for a safe environment for both of us to inhabit. 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. Owing to this, these industries can focus their resources on other meaningful processes.
Secondly, powder coatings are able to give a tougher and a thicker coating than the conventional paint coatings. Objects coated with powder are therefore able to last longer since they enjoy more protection owing to the thick coating on their surface. Furthermore, a tougher coating rarely requires any replacements to be done on it and this reduces the costs of production. Owing to the fact that no coating replacements are needed, the appearance of the coated object is also maintained over a long period of time.
Powder coating also has the advantage of making it possible for the designers to achieve more design patterns on the coated object than is possible for objects coated with other coating materials. 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.
Finally, powder coatings demand less curing periods as compared to conventional liquid paint coatings. The curing process for liquid paint coatings is done by the use of cold air being allowed to flow over the coated object and this process is usually long and uncontrolled. The sole aim of blowing cold air over the coated object is to cause the paint to dry and adhere to the surface of 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.
