Powder coatings, especially epoxy resin for automotive coating research has been more than 20 years, but because of automotive coatings require high weather resistance, high corrosion resistance, high wear resistance, and heat, light, color and other high-performance, and excellent decorative performance, development research has considerable difficulty, it is difficult to achieve breakthroughs in a short period of time. Powder coating began only for automotive parts, automotive primer, anti-stone primer, etc.,used in car finish and finish varnish in bulk until the late 90s. With the maturing of technology and the improvement of the performance of powder coating, it has been fully able to meet the performance requirements of car painting, it becomes the true sense of the automotive powder coating.
