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. Powder coating is becoming more and more prevalent due to the large number of benefits attributed to its use as we shall discuss.
Firstly, the powder coating doesn’t require the use of solvents and it therefore doesn’t release the much volatile organic compounds into the environment. The volatile organic compounds are in most cases high potential pollutants which degrade the environment. With the presence of less contaminants in the coatings, there is a chance for a safe environment for both of us to inhabit. In addition, industries dealing with powder coatings have no worries of installing pollution management equipment and this saves them the cost of production. 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. 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 retained over a long period of time owing to the fact that no coating replacements need to be done on the object.
For powder coatings, it is also possible to come up with more design patterns than can be possibly achieved when conventional paint coating is used. Owing to this fact, the clients are better served by the designers and this leads to their satisfaction-something that cannot be achieved in the conventional paint coating.
Finally, powder coatings demand less curing periods as compared to conventional liquid paint coatings. For liquid paints, the curing process is usually left to take place naturally and is brought about, in most cases, by the cold air flowing over the painted object. 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.
