Abstract: Disclosed herein is a method for assessing a shape of a bell-shaped liquid spray, including the steps of operating a spray nozzle for delivering a bell-shaped liquid spray and capturing an image of a plurality of liquid jets forming the delivered bell-shaped liquid spray during operation of the spray nozzle, and a computer program product for assessing a bell-shaped liquid spray.

Abstract: Described herein is a device for monitoring and drying and/or curing process of a coating composition applied at least partially onto at least one surface of a substrate, the device including a movable skid that includes at least one substrate holding unit, at least one lamp, at least one pattern holder including a pattern, and at least one camera, where the substrate holding unit, lamp and pattern holder are positioned on the skid relative to each other such that the light of the lamp can illuminate the pattern of the pattern holder, and the illumination can be projected onto the surface of the substrate, which is held by the substrate holding unit, and where the camera is positioned on the skid relative to the substrate holding unit holding the substrate, such that the camera is capable of recording images of the light reflected off the surface of the substrate.

Abstract: 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 at least one characteristic variable of a drop size distribution within a spray formed on atomization of the coating material composition (BZ1), and/or of the homogeneity of this spray (2), reduction of the at least one characteristic variable and/or homogeneity of the spray (3), application of at least the coating material composition (BZ1) obtained after step (3), 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 by application of (BZ1), to produce the coating (B1) on the substrate. Also described herein is a coating (B1) located on a substrate and obtainable by means of this method.

Abstract: Described here is a method for determining the mean length of filaments formed on rotational atomization of a coating material composition, the method including atomization of the coating material composition by means of a rotational atomizer including as application element a bell cup capable of a rotation (1), optical capture of the filaments formed here at the bell cup edge, by means of at least one camera (2), and digital evaluation of the optical data obtained in this way, to give the mean filament length of those filaments formed on atomization that are located at the edge of the bell cup (3), as well as methods for compiling an electronic database and for screening coating material compositions when developing paint formulations.

Abstract: Disclosed herein is a method for determining a drop size distribution within a spray and/or a homogeneity of this spray, the spray being formed on atomization of a coating material composition, which includes atomization of the coating material composition by means of an atomizer, the atomization producing a spray, optical capture of the drops of the spray formed, by a traversing optical measurement (2), and determination of at least one characteristic variable of the drop size distribution within the spray and/or of the homogeneity of the spray, on the basis of optical data obtained as per step (2). Also described herein are methods for compiling an electronic database and for screening coating material compositions when developing paint formulations, carried out on the basis of the method.
