How to choose the paint sprayer extension nozzle set?
For different types of coatings, there are three main factors to consider when choosing the aperture of the matching coating nozzle, namely, the viscosity of the coating, the volume of spraying work and the flow of coating.

Viscosity of small fluid flow resistance is also small, so the use of nozzle aperture can be smaller, the hydraulic pressure used can also be lower; and viscosity of large paint flow resistance, so in order to get enough flow rate, we must use a large diameter spray gun extension nozzle and higher hydraulic pressure. The general paint nozzle caliber is between 0.5~5.0mm, 0.5~0.7mm caliber is used for colorant, insect glue and other easy low viscosity paint spraying, 1.0~1.8mm caliber is used for nitro paint and other viscous paint spraying.
