In an electrostatic atomization coating apparatus including a nozzle head including a plurality of coating material ejection ports; a coating material chamber that is provided inside the nozzle head and to which a coating material is supplied via a coating material supply path, each of the coating material ejection ports being in communication with the coating material chamber via an individual branch coating material path; and a voltage application device that provides a potential difference between the nozzle head and an object to be coated, the coating material ejected from each of the coating material ejection ports via the coating material supply path, the coating material chamber, and the branch coating material path being brought into a charged state through application of a voltage by the voltage application device, an open/close valve device that opens and closes all of the branch coating material paths, or opens and closes a specific subset of a plurality of branch coating material paths out of all of the branch coating material paths is provided. Thus, it is possible to prevent external air from entering the nozzle head, and the coating material from leaking to the outside of the nozzle head.

An electrostatic powdering robot for a powder booth, the robot including a projector for performing electrostatic powder coating. In order to reduce the time required for powder removal from the booth and facilitate automation of powder removal, the robot further includes a robotic arm, which is articulated and which carries the projector for positioning the projector, as well as a blower, for blowing a powder removal fluid, preferably air, the robotic arm carrying the blower to position the blower inside the booth, so that the blower blows the powder removal fluid onto a surface to be de-powdered inside the electrostatic powdering booth and thereby removes the residual powder coating the surface to be de-powdered.

The present invention relates to an electrostatically sprayable cosmetic formulation having a sufficient sun protection factor, water resistance and caring effect, and which provides a sufficient, i.e. nearly full, coverage of the skin surface, when the formulation is applied on the surface of the skin by electrostatic spraying.

Devices, systems, and methods are directed to applying magnetohydrodynamic forces to liquid metal to eject liquid metal along a controlled pattern, such as a controlled three-dimensional pattern as part of additive manufacturing of an object. Electric current delivered to a meniscus of the liquid metal in a quiescent state can be directed to exert a pullback force on the liquid metal. The pullback force can be sufficient to draw the liquid metal, in the quiescent state, in a direction toward the nozzle to reduce the likelihood of unintended wetting of surfaces of the nozzle between uses of the nozzle.

Methods involving: A) placing one or more solid materials on a skin surface; after step A), B) electrostatically spraying a composition X comprising (a) one or more volatile substances selected from water, an alcohol, and a ketone and (b) a polymer having a coating forming ability directly on the skin to thereby form a coating on the skin surface; and after step B) or before step A), C) applying a composition Y, other than the composition X, comprising one or more components selected from the group consisting of (c) an adhesive polymer and (d) an oil component (d) to the skin, are useful for producing a wearable coating having a solid material fixed on skin.

Provided is a coating having a uniform and strong UV protective effect over the entire skin. A method for producing a UV protective coating on skin comprising a step of applying a composition comprising a UV protective agent to the skin, and a step of electrostatically spraying a composition comprising component (a) and component (b) directly onto the skin to form a coating on the skin, in this order or vice versa: (a) one or more volatile substances selected from the group consisting of water, an alcohol and a ketone, (b) a polymer having a film-forming ability.

A device for the powder coating of objects includes a main body on which an electrode arrangement designed for producing a powder cloud is arranged and on which a metering device is arranged above the electrode arrangement and is designed for the controlled discharge of an amount of a powder onto the electrode arrangement. A powder coating installation is equipped with at least one such device for powder coating.

A plastisol formulation configured for use in coating substrates and a method for applying the formulation. The inventive formulation has exceptional flexibility over a wide range of temperatures. It is comprised of polyvinyl chloride, a plasticizer, a stabilizer, preferably a pigment, and a UV inhibitor/light stabilizer. The formulation is applied to a substrate and then cured by exposing it to an elevated temperature.
