The present disclosure is drawn to covers for electronic, devices, methods of making the covers, and electronic devices, in one example, described herein Is a cover for an electronic device comprising: a substrate; a micro-arc oxidation layer applied on at least one surface of the substrate; and a dyeing layer on the micro-arc oxidation layer, wherein the dyeing layer comprises: from about 3 to about 10 wt% wafer based dyes based on the total weight of the dyeing layer; and from about 0.3 wt % to about 2 wt% surfactant based on the total weight of the dyeing layer.

The present disclosure relates to a method for producing a panel having a sealed panel edge, comprising at least the method steps of: providing a raw panel comprising a panel upper face, a panel lower face and at least one pair of panel edges lying opposite each other, the raw panel having a carrier plate core and a print substrate layer, which is applied to the panel upper face; forming a chamfer between at least one panel edge of the pair of panel edges lying opposite each other and the panel upper face; sealing the at least one panel edge, the sealing comprising impregnation with an impregnating agent, the impregnating agent being applied to the at least one panel edge and to the chamfer. The present disclosure also relates to a raw panel produced by means of the method and to an assembly of such a panel with a baseboard, the baseboard having a decoration side and at least one baseboard edge adjoining the decoration side, the baseboard having a carrier plate core and a print substrate layer, which is applied to the decoration side, and the baseboard edge having the impregnating agent.

A system for applying a coating composition is provided herein. The system includes a first high transfer efficiency applicator defining a first nozzle orifice and a second high transfer efficiency applicator defining a second nozzle orifice. The system further includes a reservoir. The system further includes a substrate defining a first target area and a second target area. The first high transfer efficiency applicator and the second high transfer efficiency applicator are configured to receive the coating composition from the reservoir and configured to expel the coating composition through the first nozzle orifice to the first target area of the substrate and to expel the coating composition through the second nozzle orifice to the second target area of the substrate.

This disclosure provides cool paints and paint systems tailored for solar heat management comprising (a) hydroxyl-containing fluorocarbon polymer as binder, (b) an effect pigment, and (c) an IR transparent pigment. Specifically, the dark color paints exhibit higher than 40% total solar reflectance (TSR) and excellent weathering properties e.g., maintaining at least 80% gloss after two-year of exposure to solar irradiation in field test.

A coating of an outer plate contains a perylene-based pigment, and satisfies (R.sup.OH(P)/R.sup.OH(OA))≥74, where R.sup.OH(P) is the highlight reflectance of the coating of the outer plate at a peak wavelength at which reflectance reaches the maximum value in a spectral reflectance curve, and R.sup.OH(OA) is the average highlight reflectance of the coating of the outer plate in a complementary wavelength range. A coating of an inner plate part contains a perylene-based pigment and an iron oxide-based pigment, the content of the perylene-based pigment in the coating of the inner plate part is in units of PWC, and the mass ratio of the content of the iron oxide-based pigment to the content of the perylene-based pigment in the coating of the inner plate part is 3-20%.
