摘要:
A silver-plated structure formed on a surface of a metallic base material includes: a pretreatment layer formed by washing the surface of the base material with a pretreatment agent; a resin paint film layer formed on a surface of the pretreatment layer; and a silver plating layer formed on a surface of the resin paint film layer. The silver plating layer includes: a silver film formed by a silver mirror reaction; an undercoat film that causes the silver film to adhere to the surface of the resin paint film layer; and a topcoat film that protects a surface of the silver film.
摘要:
Thermoplastic compositions containing certain salts of fluorinated sulfonic acids adhere especially well to coatings (paints) applied to the surface(s) of that composition. Useful parts that can be made include painted automotive body parts, appliance cases, and other parts with painted aesthetically pleasing surfaces.
摘要:
Described is a method of coating a metallic substrate comprising: providing a metallic substrate; applying an electrocoating composition by a cathodic electrocoating process to the substrate; and applying to the electrocoated substrate an aqueous coating composition comprised of a siloxane material. Also described is the product produced by the process having improved hardness, adhesion, corrosion resistance, abrasion resistance and appearance.
摘要:
It is an object of the present invention to provide a method of coating a square wire capable of providing an insulated wire of a square wire that has a high dielectric breakdown voltage. A method of coating a square wire comprising a step of carrying out cationic electrodeposition on a square wire to form an insulating film thereon, by using a cationic electrocoating that stored in an electrocoating bath, wherein the shifting speed of the square wire in the electrocoating bath is set in a range from 1 to 80 m/min; the shortest distance from a liquid-contact portion of the square wire onto the cationic electrocoating to an electrode is set longer than 1/2 of the total shift distance of the square wire from the liquid-contact portion of the square wire to a liquid-separation portion in the electrocoating bath, the cationic electrocoating contains a resin composition of which a hydratable functional group is reduced directly by electrons and passivated, resulting in deposition of a film, and the cationic electrocoating contains crosslinked resin particles.
