Described herein is a method for producing at least one coating (B1) on a substrate, including provision of a coating material composition (BZ1) (1), determination of a mean filament length of filaments formed on rotational atomization of the coating material composition (BZ1) provided as per step (1) (2), reduction of the determined mean filament length (3), application of at least the coating material composition (BZ1) obtained after step (3), with reduced mean filament length, to a substrate, to form at least one film (F1) (4), and physical curing, chemical curing and/or radiation curing at least of the at least one film (F1) formed on the substrate as per step (4), to produce the coating (B1) on the substrate (5). Also described herein is a coating (B1) located on a substrate and obtainable by means of this method.

A state determination device determines a state of a paint device including an air motor that rotates by a supply of a gas, a rotational shaft that serves as a rotational center of the air motor, and a rotary atomizer head that is connected to the rotational shaft and sprays paint. The paint device further includes a vibration detection unit that detects a vibration of the paint device, and the state determination device includes a frequency component acquisition unit and an abnormality determination unit. The frequency component acquisition unit acquires a frequency component caused by a contact between the rotational shaft and the air motor from a detection result by the vibration detection unit. The abnormality determination unit determines whether an abnormality of the air motor exists or not based on an acquisition result by the frequency component acquisition unit.
