Powder coating is by far the youngest of the surface finishing techniques in common use today.
It was first used in Australia about 1967. Powder coating is the technique of applying dry paint to a part. The final coating is like 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.
It Looks Like Paint But It Acts Like Armour.
It's tough. It looks great. And it lasts a long, long time. Powder coating is a superior finish that's found on hundreds of products you come in contact with each day. It makes products durable, attractive, and scratch-resistant, too.
How Does It Work?
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.
