Atomization
Atomization is the process of using pressurized air to reduce liquids into very small particles. When utilizing a spray gun to apply a coating, proper atomization is required to transfer the coating onto a targeted object.Proper atomization will result in a controlled spray, where the coating particles propelled from the spray gun nozzle will create a smooth uniform finish. Adjustments to the air pressure will alter the particle size of the coating and provide different results in the wet finish.
Higher air pressures (15-30 PSI) will reduce particle size and will create a smooth wet finish.
Lower air pressure (5-15 PSI) will increase particle size and can create a textured wet finish.
