A coating film is provided on the surface of a car body of an automobile and includes a plurality of protruding portions extending from the front toward the rear along the car body.

The present invention relates to a peelable coating film having silica particles fixed to a surface thereof, a coating material for hydrophilic-coating-film formation which includes colloidal silica, an alkali metal silicate, and an aqueous medium, and a coating-material set including the coating material for hydrophilic-coating-film formation and a coating material for peelable-coating-film formation including an aqueous dispersion type resin composition.

A method for manufacturing of a multilayer PVC semi-finished product, in particular a multilayer PVC synthetic leather or a multilayer PVC foam sheet, the method comprising the steps of:

a. Coating a coated or uncoated carrier web with a PVC plastisol, whereby a carrier web coated with an ungelled plastisol layer is obtained; thereafter
b. Gelling the ungelled plastisol layer, whereby a carrier web coated with a gelled plastisol layer is obtained; and thereafter
c. Cooling the carrier web coated with the gelled plastisol layer; characterized in that the coating comprises coating the carrier web with at least two PVC plastisols one above the other, simultaneously or in immediate succession. A corresponding apparatus is further described.

Methods and coating compositions for application to a substrate utilizing a high transfer efficiency applicator are provided. An exemplary method includes providing the coating composition to the high transfer efficiency applicator; applying the coating composition onto the substrate utilizing a high transfer efficiency applicator to form an applied layer, wherein a loss of volatiles after application through the high transfer efficiency applicator is less than about 1 weight percent based on a total weight of the coating composition; performing a partial polymerization via radiation of the applied layer; and after performing the partial polymerization of the applied layer, thermally curing and drying the applied layer. An exemplary coating composition has a pre-application viscosity, at a shear rate of 1000 s.sup.−1, of less than about 100 centipoise (cP), and a post-radiation-exposure viscosity at a shear rate of 0.1 s.sup.−1 of from about 500 cP to about 150,000 cP.

There is provided an adhesive application apparatus capable of efficiently applying an adhesive without inhibiting curing of the adhesive. An adhesive application apparatus of the present invention includes a mounting table 10, an adhesive dosing unit 20, and an ultraviolet irradiation unit 30, and it applies a delayed-ultraviolet-curable adhesive 200 to a surface of a panel 100. The panel 100 is mounted on a mounting surface S10 of the mounting table 10. The adhesive dosing unit 20 applies the adhesive 200 to the surface of the panel 100 mounted on the mounting table 10 by discharging the adhesive 200 from an adhesive dosing port H20. The ultraviolet irradiation unit 30 irradiates the adhesive 200 dosed from the adhesive dosing port H20 with ultraviolet light L. Here, the ultraviolet irradiation unit 30 irradiates the adhesive 200 with the ultraviolet light L along the mounting surface S10 before the adhesive 200 dosed from the adhesive dosing port H20 is applied to the surface of the panel 100.

A coating device coats a coating region of a to-be-coated object having a convex curved surface. A coating device includes a head, an arm, and a controller. The head includes a nozzle surface. The arm holds the head. The controller controls movement of the head via the arm. A controller moves a head in a first direction along an end portion of a coating region in a posture in which a gap between a nozzle surface located on an end portion side of the coating region and a to-be-coated object is smaller than a gap between the nozzle surface located on a center side of the coating region and the to-be-coated object.

A coating device includes a head, a wiping mechanism, an arm, and a controller. The head includes a nozzle surface for discharging a coating material. The wiping mechanism wipes the nozzle surface. The arm holds the head. The controller controls movement of the head via the arm. The controller relatively moves the head with respect to the wiping mechanism to wipe the nozzle surface.

According to one embodiment, a coating apparatus includes a coating bar configured to face a member to be coated, and a plurality of nozzles configured to supply a liquid toward the coating bar. A number of the nozzles is 3 or more. An arithmetic mean roughness Ra of at least a part of a surface of the coating bar is not less than 0.5 μm and not more than 10 μm.
