An Experimental Study on the Correlation between Spray Distance, Coating Thickness and Waste Reduction

For car refinishing painting sites, the distance between spray guns and panels directly affects the thickness of the paint film, the thickness of the paint film increases as the spray distance decreases, and as the spray distance increases, the coating thickness decreases. Also, the faster the spray gun moves, the thinner the coating becomes, and the slower the spray gun moves, the thicker the coating becomes. That is, if the spray distance is close and the spray gun is slow, the thickness of the paint film increases, and if the spray distance is increased and the gun movement is fast, the thickness of the paint film decreases. The key is to fully understand the characteristics and types of spray guns used and to reproduce the uniform coating thickness and quality required for painting at any time.
