Abstract:
The present invention provides a method for forming an oxide film by which normal formation of an oxide film is always achieved without receiving an influence of a change in the atmosphere, a metal oxide film having a low resistance can be formed, and a high efficiency of film formation is obtained. In the present invention, a raw material solution containing an alkyl compound is formed into a mist and ejected to a substrate (100) in the atmosphere. Additionally, an oxidizing agent that exerts an oxidizing effect on the alkyl compound is supplied to the mist of the raw material solution. Through the above-described processes, an oxide film is formed on the substrate in the present invention.
Abstract:
The invention relates to a method for coating the surface of inorganic particles in an aqueous phase, particularly of titanium dioxide pigment particles, with a dense skin of silicon dioxide and at least one further inorganic compound, particularly with aluminum oxide, where the coating largely consists of separate layers. Titanium dioxide pigment particles, treated with SiO2 and Al2O3 according to the invention, are characterized by improved tinting strength, reduced acid solubility and an isoelectric point shifted towards higher pH values.
Abstract:
The invention relates to a patterned transparent conductive film, comprising areas with higher conductivity and areas with lower conductivity, wherein in the areas with higher conductivity nanoobjects are disposed in a binder matrix such that the nanoobjects are interconnected and thereby form an area with higher conductivity and wherein in the areas with lower conductivity the nanoobjects are structurally intact and are coated with an insulating coating material. The invention further relates to a process for producing such a patterned transparent conductive film comprising areas with lower conductivity and areas with higher conductivity, comprising following steps: (a) applying an ink comprising electrically conductive nanoobjects and a binder on a substrate, forming a first layer, wherein the amount of conductive nanoobjects is such that the first layer is conductive after drying; (b) drying of the first layer; (c) applying a mixture comprising an insulating coating material or a precursor of an insulating coating material on that parts of the first layer which shall form the areas with lower conductivity, wherein the insulating coating material or the precursors form an insulating coating around the electrically conductive nanowires; (d) drying of the coated substrate.

Abstract:
The disclosure relates to a method for coating a substrate with a lacquer. First, the lacquer is uniformly applied to the substrate. Then, the solvent proportion of the lacquer applied to the substrate is reduced, and the coated substrate is exposed to a solvent atmosphere. In some embodiments, the lacquer is heated. The invention also relates to a device for planarising a lacquer layer.
Abstract:
Described is a method for coating light alloy rims, coating materials for use in this method, and the coated light alloy rims obtained in this way. More specifically, described is a method for coating light alloy rims with at least three layers comprising a primer layer (A), a base coat layer (B), and a clear coat layer (C), each of which are a layer of different coating materials. The method comprises providing a substrate; applying the primer layer (A) directly to the substrate; applying the base coat (B) layer; applying the clear coat layer (C); and curing the layers of different coating materials by high-energy radiation.
Abstract:
An inkjet-based process for programmable deposition of thin films of a user-defined profile. Drops of a pre-cursor liquid organic material are dispensed at various locations on a substrate by a multi-jet. A superstrate that has been bowed due to a backside pressure is brought down such that a first contact of the drops is made by a front side of the superstrate thereby initiating a liquid front that spreads outward merging with the drops to form a contiguous film captured between the substrate and the superstrate. A non-equilibrium transient state of the superstrate, the contiguous film and the substrate then occurs after a duration of time. The contiguous film is then cured to crosslink it into a polymer. The superstrate is then separated from the polymer thereby leaving a polymer film on the substrate. In such a manner, non-uniform films can be formed without significant material wastage in an inexpensive manner.
Abstract:
Apparatus for curing the coating of a workpiece (1), which comprises at least one tank (2) with inert gas heavier than air into which the workpiece (1) is inserted, and at least one UV-radiation source (3) that generates radiation that falls on the workpiece (1) to bring about the curing. The apparatus also comprises an extraction area (4), a recirculation circuit (5) and an insertion area (6), where, respectively, inert gas is extracted from the tank (2), recirculated, and reintroduced into the tank (2). At least one inert gas cooling member (7) is situated in the recirculation circuit (5), thus preventing the inert gas inside the tank (2) from overheating and reducing the risk of instability in the inert gas atmosphere.
