Powder coating is an advanced method of applying a decorative and protective finish to a wide range of materials and products that are used by both industries and consumers. The powder used for the process is a mixture of finely ground particles of pigment and resin, which is sprayed onto a surface to be coated. The charged powder particles adhere to the electrically grounded surfaces until heated and fused into a smooth coating in a curing oven. The result is a uniform, durable, high-quality, and attractive finish. Powder coating is the fastest-growing finishing technology in North America, representing over 10% of all industrial finishing applications.
Is powder coating friendly to the environment?
Negligible VOCs - Powder coatings contain no solvents and therefore emit negligible, if any, polluting VOCs into the atmosphere.
Less exhaust - Powder coating is a clean process, allowing exhaust air from the coating booth to be returned to the plant, and less oven air is exhausted to the outside.
Reusable overspray - Up to 98% of powder overspray can be retrieved and reused.
No costly waste disposal equipment - Unused powder can be reclaimed and returned to a hopper for recirculating through the system, with negligible waste.
Is powder coating efficient ?
Powder coating is not only efficient, it is economical as well.
Lower heating costs for curing oven - The exhaust requirements for a powder coating oven are lower than solvent-based coatings, resulting in energy savings.
Greater operating efficiency/lower unit costs - No drying or flash-off time is required. Parts can be racked closer together on conveyors and pass more quickly through the production line.
Lower reject rates - More parts can be coated automatically with fewer rejects because powder coating does not run, drip or sag.
High utilization efficiency - With proper application equipment, powder materials and efficient recovery methods, one-coat application and 95%-98% powder utilization efficiency are readily available. If more than one color is desired, color changes can be made quickly.
Lower personnel costs - Minimal operator training and supervision are required for a powder line. Employees prefer working with dry powder because of lack of fumes, reduced housekeeping problems and minimum clothing contamination.
Simplified permit process - The permitting process for a powder coating operation is simpler. Compliance with federal and state regulations is also easier, saving both time and money.
Is powder coating versatile & durable?
Most importantly, powder coating provides a durable and high-quality finish, with a wide range of performance properties including excellent resistance to impact, abrasion, heat, stains, extreme weather and fading from sunlight. Texture selections range from smooth surfaces to a wrinkled or matte finish. Rough textures are also available, designed specifically for hiding any surface imperfections. And color selection is virtually unlimited, including clearcoats.
