An application device for the application in series of a paint or other coating compositions to motor vehicle bodies or add-on parts thereof has a nozzle print head which contains a plurality of nozzles arranged, for example, in one or more rows, which apply the coating composition to the surface to be coated as continuous jets or individual drops. The nozzle print head is arranged on a multi-axis coating robot. In contrast to application devices of this type known hitherto, the coating composition consists of at least two components which are to be mixed together, such as, for example, 2K paint, which are fed to the nozzle print head via separate supply lines for jointly supplying the nozzles.

A low pressure limited overspray handheld aerosol spray gun for spraying a two-component adhesive, a method for spraying a two-component adhesive and a two-component adhesive obtainable by that method. In manufacturing of larger objects, such as matrasses and furniture, adhesives are often applied to fix parts of the large object together. Most adhesives are applied using either air-spray equipment or air-assisted spray equipment.

A coating comprises a resin solution including a solution of neoprene latex and liquid asphalt emulsion and an accelerator solution including an aqueous solution of zinc sulfate powder and water. A spray system for applying the coating includes a spray gun having first and second nozzles, a first pump fluidly connected between the first nozzle and a resin solution reservoir for delivering the resin solution to the first nozzle at a first fluid pressure, and a second pump fluidly connected between the second nozzle and an accelerator solution reservoir for delivering the accelerator solution to the second nozzle at a second fluid pressure different from the first pressure. The accelerator solution may be aerated by a source of compressed air prior to discharge from the second nozzle.

The invention relates to a spray device having a spray nozzle unit and at least one further spray nozzle unit. Each spray nozzle unit has at least one spray nozzle body, wherein at least one spray nozzle body comprises a chamber for receiving a pressurized fluid. The chamber is bound by a spray wall having at least one spray orifice that extends through the spray wall and opens to an external environment. Each of at least one orifice in a spray wall has a substantially identical predetermined size lying in a predetermined range and releases a mono disperse spray jet of the pressurized fluid fed from the associated reservoir. The range within the first spray nozzle unit differs from the range within at least one further spray nozzle unit; particularly, the ranges do not overlap.

In one example, a liquid mixture nozzle for flowing a liquid mixture therethrough includes a body having a flow inlet and a flow outlet. The flow inlet is configured to couple to a first piece of piping and the flow outlet is configured to couple to a second piece of piping. The liquid mixture nozzle also includes a converging section having a decreasing diameter positioned adjacent the flow inlet, an orifice positioned at a narrow end of the converging section, an intermediate section having a constant diameter positioned adjacent the orifice, a diverging section having an increasing diameter positioned adjacent the intermediate section and the flow outlet.

A two component sprayable adhesive and system for spraying is provided. The two component adhesive may have an adhesive, and an activator. These components are mixed after spraying, either in the air or on a substrate. The activator destabilizes the adhesive making it more tacky and effective. In at least one of the two components, an additive is provided to provide a visual indication that the components are mixed and/or properly mixed in the intended ratio.

A coating method that improves uniformity of coatings that settle on more complex objects, like porous substrates, or substrates with hollows or curvy forms, and a device for implementing the method. The coating device includes a deposition chamber, and a loading structure configured to load an object into a position in the deposition chamber and unload the object from the deposition chamber. The coating device includes an atomization element in a bottom part of the deposition chamber, the atomization element creating into the deposition chamber an aerosol volume that includes a floating aerosol region in the top part of the deposition chamber. The loading structure is configured to load the object into a position in the floating aerosol region in the deposition chamber.

A spray system for mixing multi-part liquids and spraying a mixed liquid product onto a spray target includes first and second spray nozzles. The first spray nozzle dispenses a first constituent liquid part of the mixed liquid. A second spray nozzle dispenses a second constituent liquid part of the mixed liquid product. The first spray nozzle and the second spray nozzle are oriented relative to each other and the spray target such that the first constituent liquid part and the second constituent liquid part impinge on each other while airborne and prior to reaching the spray target.
