Unlike liquid coating processes whereby liquid paints are used to do the coating, powder coating can only be achieved by the use of a dry powder. Normally, the powder coating doesn’t explore the option of using solvents that is usually compulsory for 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.
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. In addition, industries dealing with powder coatings have no worries of installing pollution management equipment and this saves them the cost of production. This allows these industries to invest money that would have otherwise gone into pollution management into other processes.
Secondly, with powder coatings, a tougher and a thicker skin can be attained as opposed to the use of 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. In addition, thicker and tougher coatings seldom require replacement and this cuts down on the costs of replacing the coatings. 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.
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. 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 purpose of the dry air is to force the paint coat to dry and stick to the coated object. For powder coating however, the curing process is usually regulatable and can be induced by the production team in order to force a quicker curing process which eliminates unnecessary time losses in the production cycle.
