Powder coating: Good contamination control prevents defects from start to finish

摘要

With its durability, re-stance to corrosion and high quality finish, powder coating has be-come a preferred finishing choice among both consumers and manufacturers; and good contamination-control techniques can ensure that a powder coating operation is producing the highest quality, defect-free finish possible. In the late 1960s, powder coaling emerged on the horizon as an attractive alternative to other methods of surface costing. With its durability resistance to corrosion and high quality finish, powder coating quickly became a preferred finishing choice among both consumers and manufacturers. In addition, powder coating doesn't produce the hazardous by-products—overspray waste, wastewater sludge, and volatile organic compounds (VOCs)—that are a consequence of more traditional surface-coating techniques, making powder coating a "green" alternative in a market where environmental regulations are becoming ever more stringent. Today, powder coating is used in nearly every industry— furniture, appliances, medical devices, and automotive are just a few.
