Powder coating is justifiably superior to wet spray in so many ways. If your part is capable of being powder coated, there is really no reason why you would be compelled to choose otherwise. It's generally less expensive because the process is quicker. Powder coating is not subject to the extra time it takes to set up and break down from a wet spray product. Relative to wet spray, the paint dries very quickly. The parts can be prepared for delivery as soon as they come out of the oven and cool down.
Powder coating is more environmentally friendly than wet spray because it does not involve the potentially harmful chemicals used in a wet spray product. Unlike traditional wet spray painting methods, we simply use a clean and efficient electrostatic powder coating process. No Volitile Organic Compounds are emitted. New laws and regulations make powder coating the wave of the future. Already, California is tightening environmental rules regarding wet paint, so it is only a matter of time until similar rules are enacted in Canada.
Wet spray involves the use of chemicals that can be potentially hazardous to people and the environment if not handled properly. Powder coating uses an air gun to blow away misapplied powder rather than resort to the chemical thinners that wet spray requires to clean up or fix application errors.
The powder coating process yields parts that are uniformly coated with a minimum expenditure of powder, which translates to a superior coating for less money than traditional wet spray methods. Further, the thermal bonding process makes for a much more durable finish than wet spray.
