Introduction

Use of powder paint as an alternative for liquid paint has created a great evolution in the color quality. Liquid paints create environmental pollution because of possessing evaporative chemical solvents during drying, and they are harmful for human health. The powder paint entered to the market for the first time in 1962. Keeping of 100% solid state, in addition to environmental pollution prevention, has offered incomparable quality against liquid paints to the industry. Powder paints are now taken 15% of the market share and compete with traditional liquid paints. Due to environmental laws on pollution and waste removal, replacement of liquid paints with powder paints becomes more important every day.
