separating something into fine particles.

A process whereby paint is broken into finely divided droplets and then applied onto the substrate. In modelling this applies to the process of airbrush ing, where paint is forced through the airbrush nozzle under pressure. The process is almost always enabled by thinning the paint down with a suitable thinner. It is important to get the correct degree of atomisation otherwise satisfactory end results will not be obtained, and usually some experimentation with either or both of paint consistency and airbrush pressure is required.

The atomising or breaking up of the liquid coating into a fine mist as it is sprayed. Good atomisation is necessary to produce a quality finish.

The distribution of powder particles with air to form a fine pattern during the spraying application process.

The dispersion of a molten material into particles by a rapidly moving gas or liquid stream or by mechanical dispersion.
