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. For the powder to remain intact, it is required that it is cured using heat which causes the powder to flow over the surface of the material being coated. 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. 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. This allows these industries to invest money that would have otherwise gone into pollution management into other processes.
Unlike the use of paint coatings where only a very thin coat can be attained, powder coatings do not have this limitation. Objects coated with powder are therefore able to last longer since they enjoy more protection owing to the thick coating on their surface. Over and above this, coating replacement costs are also reduced and this is a major advantage for people seeking to manage their production costs. 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.
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. 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.
