What is powder coating?
Powder coating is a dry finishing process, using finely ground particles of pigment and resin, which are electrostatically charged and sprayed onto a part to be coated. The charged particles adhere to the parts until melted and fused into a tough, even coating through the application of heat and energy.
Powder coating is the technique of applying dry paint to a part. The final cured coating is the same as a 2-pack wet paint. In normal wet painting such as house paints, the solids are in suspension in a liquid carrier, which must evaporate before the solid paint coating is produced. In powder coating, the powdered paint may be applied by either of two techniques.
Powder coating is a dry finishing process. Finely ground particles of pigment and resin are electrostatically charged and sprayed onto the products to be coated. The parts to be coated are electrically grounded, so that the charged particles adhere to them until melted and fused into a solid coating in a curing oven. The result is an attractive, durable, high-quality finish. The powder coating process itself offers another advantage — it is environmentally friendly…virtually pollution-free! Unlike liquid paint, no solvents are used, so only negligible amounts of VOCs are released into the air. In addition, unused or oversprayed powder can be recovered, so any waste is minimal and can be disposed of easily and safely.
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 industriesand 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.
Powder coating is a dry-finishing process for metal products. A finely ground mix of pigment and resin is electrically charged and sprayed on the oppositely electrically charged product to be coated. Electrostatic adhesion holds the particles onto the metal while it is baked onto the product in a 400oF curing oven. The pigment and resin mix becomes bonded to the metal forming an extremely durable, high-quality finish that can withstand a large range of temperatures and is very resistant to weather.
