Benefits of Powder Coating

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 powder coating 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.

Economic Advantages
• Up to 99 percent of over sprayed powder can be reclaimed. Captured powder is typically sieved and returned to the feed system, mixed with virgin powder and reused. The high reclaim efficiencies of Nordson powder coating booths typically allow powder coaters to achieve overall powder coating system efficiency in excess of 95 percent.
• Very high material utilization rates minimize waste and associated disposal costs.
• Clean-up and waste disposal costs are minimal, since practically all powder coating materials contain no VOCs and are not considered hazardous waste.
• Eliminates use of solvents and the need to maintain viscosity balance and flash-off time requirements.
• Allows users to achieve a broad range of coating thicknesses (typically ranging from one to eight mils) in one pass without runs or sags.
• Minimizes rejects since damaged coatings can be blown off before heat is applied to the parts.
• Eliminates the need for fresh air make-up and reduces air conditioning costs since all air is typically returned to the plant.

Ease of Application
• One-coat coverage often reduces production time and related costs.
• Wraparound effect achieves full, two-side coverage of some products after spraying only one side.
• Coating process is easily controlled and automated.
• Powder coatings require no pre-mixing, viscosity adjustments or stirring.

Finish Quality
• Several available powder materials provide coating uniformity and consistent edge coverage, and deliver a wide range of coating thicknesses for superior corrosion resistance.
• Numerous powder formulations meet the broadest spectrum of requirements for final finish color, gloss, hardness, weathering, abrasion and chemical resistance.
