    Abstract: The present disclosure proposes a process for producing a structured antiwear film, comprising the process steps of: a. providing a base antiwear film, b. applying a formable outer paint layer to at least part of the area of the base antiwear film, c. at least partially structuring the outer paint layer by means of a digital printing process to create a structuring of the outer paint layer, and d. curing the outer paint layer such that the outer paint layer is first partly cured, wherein UV radiation with a wavelength in a range from ≥150 nm to ≤250 nm is used for the partial curing, and wherein the outer paint layer is then cured to completion, and wherein e. the outer paint layer, before being supplied to the printing unit for partially structuring the outer paint layer and/or during the printing operation for partially structuring the outer paint layer in the printing unit, is treated with means for changing the electrostatic charge of the outer layer, in that the outer layer is electrostatically discharged.

    Abstract: A method of manufacturing at least one workpiece having a structured layer on a support member (1) is disclosed. The method comprises the following steps: step (S10): Providing the support member (1) having a liquid and curable layer (2) on a support member surface (7); step (S12): applying a masking agent (3) onto the layer (2) such that the masking agent (3) has a first layer thickness at a first location (4) on the layer (2) and that the masking agent (3) has a second layer thickness at a second location (5) on the layer (2), wherein the first layer thickness is greater than the second layer thickness; step (S14): curing the layer (2), wherein material of the layer (2) at the first location (4) below the masking agent (3) applied at the first location does not cure or cures less than material of the layer (2) at the second location (5) below the masking agent (3) applied at the second location; and step (S16): Removing uncured material of the layer (2) so that the cured material of the layer (2) forms the structured layer having a height profile on the support member (1). Furthermore, a device for carrying out the method is disclosed.

    Abstract: A method of mercury-free photochemical micro-/nano-encapsulation of an active material is a process for obtaining micro-/nano-capsules by means of curing by UV LED radiation at ambient or even cold temperatures. A stirrer photo-reactor made from glass or transparent plastics can be used but mixed flow reactor could be also employed. Appropriate mixing is sufficient to expose all droplets, which contain an active material surrounded by curable-shell materials in the emulsion to the LED radiation. Using the optimum light intensities and reactions' times is critical for encapsulating the active material with a high efficiency and producing a high quality micro-/nano-capsules, Solar monochromator device can also be used as long as it generate the same radiation with a narrow/single wavelengths as the LED device. Light emitted diode (LED) is a mercury-free UV radiation source with a long operating life time and an instant ON-Off. it has a high efficiency, a very low cooling requirements and cost-efficient in photochemical encapsulation. It reduces the time of microencapsulation from 6 hours to a less than 5 minutes. It has a significant decrease in manufacturing cost, waste-water, unconverted monomers, and leftover active phase change material (PCM) compared to other methods. Conversion of more than 90% of monomers can be achieved, and encapsulation efficiency can reach 100% at optimum conditions. This is in addition to the ability of this invented technology for encapsulate volatile and heat sensitive active materials at ambient as well as low temperatures. Normal glass or transparent plastics can be used as a reactor material. Only the matched useful wavelength radiation is emitted by LED without having other wavelengths which might have a bad impact on the encapsulation process.

    Abstract: The present disclosure provides processes and systems for generating a coated article having a virtual embossing effect. A process comprises applying a wet layer of a coating composition on a substrate, the composition comprising a curable resin and a plurality of flake-form pigments; forming a pattern of the pigments in the wet layer; and curing the wet layer thereby forming a cured layer, wherein the formed pattern of the pigments is capable of remaining substantially unchanged after curing and results in a virtually embossed effect of the cured layer. A coating system comprises a substrate; a coating composition comprising a curable resin and a plurality of flake-forming pigments; means for applying a wet layer of the composition onto the substrate; means for forming a pattern of the pigments in the wet layer; and means for curing the wet layer to form a substantially cured layer. The cured article derived from the processes and systems preferably may have a substantially even surface.

    Abstract: Disclosed is a method of at least partly encapsulating at least one component arranged on a substrate. The method comprises the step of dispensing at least one drop of a polymer on and/or around the component by jetting, using a nozzle, to obtain a dispensed polymer. The method further comprises at least partly curing the dispensed polymer by exposing the dispensed polymer to a light source to obtain a cured polymer. The method further comprises protecting the nozzle while at least partly curing the dispensed polymer, and repeating the steps of dispensing, at least partly curing and protecting, thereby at least partly encapsulating the component.
