Abstract:
A method for painting a metal alloy molding material with high adhesion and the painted metal alloy molding material are provided to offer high adhesion on a coating surface of the metal alloy molding material. A method for painting a metal alloy molding material with high adhesion includes the following steps of: performing an alkali degreasing process of the metal alloy molding material(201); washing the metal alloy molding material of a first base material with water or purified water or warm water; drying the metal alloy molding material of a second base material; spraying flame of fuel gas including a modifier compound of which boiling point is 10°C~105°C on the surface of the material; and applying a coating layer which is a design layer on the material.

Abstract:
A method includes masking at least one hole (209) of an article (200) with a paste, wherein the hole (209) opens onto a surface (220) of the article (200), applying a coating (260) to the surface (220) of the article (200), and removing the paste including contacting the paste with a water containing liquid/environment to dissolve or re-disperse the paste, leaving at least one open hole (209) in the surface of the coated article (200). The paste includes about 20-80wt% of a filler material, about 0.5-20wt% of a hydrogen phosphate compound, about 0.5-15wt% of a polyhydroxy compound and about 5-25wt% of water. The filler material has an average particle size in a range of about 0.1-100 microns, and includes a first material which includes alkali metal doped alumina, zirconium oxide, titanium oxide or a combination thereof and a second material which includes a silicate. A weight ratio between the first and second materials is in a range of about 1-10. A dry plug obtainable by precuring and molding the paste and suitable to be inserted into the holes is also claimed.
Abstract:
The present invention relates to a method for producing a superamphiphobic coating on a substrate, said method comprising the steps of a) providing a substrate, b) generating a plasma in a treatment space, under atmospheric pressure, using a dielectric barrier discharge, by supplying a plasma gas (6) between at least a first and a second electrode (2 and 3) connected to alternating current (AC) power means (7), said electrodes (2 and 3) defining said treatment space (5), c) introducing into said plasma a coating forming material selected from the group consisting in fluoro-acrylate monomers, fluoro-alkyl acrylatemonomers,fluoro-methacrylate monomers, fluoro-alkyl methacrylatemonomers, fluroro-silane, monomers or a combination thereof, d) exposing at least a part of the surface of said substrate to said plasma comprising said coating forming material in multiple successive passes within said treatment space by moving said substrate, said at least first and/or second electrode (2, 3), or both, without stopping, from one pass to another, the generation of the plasma and said introduction of said coating forming material into said plasma.
Abstract:
A method for surface preparation of solid substances by which the solid substances can be improved in the tight adhesion to coating films made from ultraviolet-curing resins or the like; and surface-prepared solid substances. The method comprises treating the whole or part of a solid substance with a flame of a fuel gas containing a specific silicon compound having a flash point ranging from 0 to 100°C and a boiling point ranging from 105 to 250°C, e.g., hexamethyldisilazane, vinyltri- methoxysilane, trifluoropropyltrimethoxysilane, or 3-chloro- propyltrimethoxysilane to conduct flame silicification.
Abstract:
Plasma spraying of particulate thermotropic liquid crystalline polymers onto the surfaces (14) of composite and metallic structures. The present plasma spray process employs a conventional direct current electric arc plasma spray gun (12) in which an inert plasma gas is introduced, caused to swirl, and discharges as a rotating plasma flame having an exceptionally high temperature, above about 14000 DEG K, into which the particulate liquid crystal polymer is discharged for melting and propulsion onto the target surface (14). The target surface (14) preferably is preheated, and the molten particles deposit and cool to form a build up of the desired thickness. Cooling is regulated by post-heating the deposit to a temperature between about 200 DEG F and 500 DEG F.
