A method for producing a gas sensor element, for covering a detection portion (150) by an inner protection layer (21) and an outer protection layer (22), including: a first dipping step of dipping the gas sensor element into a first slurry S1 for the inner protection layer, to form a first coating film (700) on a front end surface (100c) and a peripheral surface (100d); a drying step of drying and solidifying the first coating film; a second dipping step of dipping, without removing the first coating film, the gas sensor element into a second slurry S2 for the outer protection layer, to form a second coating film (800) on a surface of the solidified first coating film; and a scraping-off step of performing scraping-off on the second coating film so as not to scrape-off the first coating film, to remove a part of the second coating film.

A process for coating of a substrate is provided, comprising: (a) applying a first layer of a liquid solvent-free UV-curable primer coating composition to a substrate surface; (b) curing the first layer UV irradiation; (c) optionally applying and curing additional layers of a liquid solvent-free UV-curable coating composition; (d) providing a granular material, having an average particle size of 60-600 mm, to the coating; (e) applying a final layer of a liquid solvent-free UV-curable finisher coating composition; and (f) curing the final layer by irradiation with UV light. The coating compositions comprise 20-90 wt % UV-curable resin, 5-70 wt % filler, 0.1-10 wt % photoinitiator and less than 5 wt % solvent, based on total weight of the coating compositions.

A method for painting a component such as a motor vehicle body component includes applying to the component a base coat layer, a pattern such as a decorative strip or a graphic element, and applying a clear lacquer coat. The pattern (7) is applied to the base coat layer without interposing a clear lacquer coat. A corresponding painting facility is provided.

Applicant discloses a two part polymer mix for use in the aircraft industry that is applied with pneumatic mix and spray gun. The two part cartridge is used in the mix and spray gun so the mix is applied immediately upon mixing, but the two components are kept separated unless the gun is applying the mix. The mix cures to form a clear sealant that allows for inspection of cracks and corrosion beneath the sealant. It cures quickly so that the coated part may be further processed, for example in the assembly line during aircraft build.

The purpose of the present invention is to obtain a method for forming an excellent multi-layer coating film of high chroma and brightness and a rich color. With the method, color mottling does not occur easily in the coating film and the design obtained is homogeneous even without strict control of variations in film thickness during coating. The method for forming the excellent multi-layer coating film comprises: forming a metallic base coating film on the surface of the object to be coated by applying a metallic base coating containing a shiny material; then forming a color base coating film by applying a color base coating; subsequently forming a clear coating film by applying a clear coating on the color base coating film; and heat-curing the metallic base coating film, the color base coating film and the clear coating film obtained. In the method, the light reflectance of the metallic base coating film is in a specified range and the light transmittance of the single color base coating film obtained by heat-curing the color base coating film as a single film is adjusted to a specified range.
